Comparing water filtration to a power cable doesn’t work, they are two different things. Water from the city pipes will not get cleaner by replacing your in home pipes. You incorrectly compared it to adding filters which would clean the water. Replacing the pipe won’t filter the water so the water will be the same. Power from the wall will not “get better” by replacing the cable, it can only be “less bad” as the cable eats up electricity due to resistance, and using 12awg over 14awg would assist in that. The only way to improve the power quality would be by running through power conditioner, which would be similar to a water filter. At that point you’re trying to “clean it” using actual tools and not just a cable. The only thing a cable can do is hurt the signal. If you want to claim that it makes an IMPROVEMENT, and not a negative change to signal that you perceive as “better” eg: HF roll off, then prove us all wrong and runs the tests between cables. Gene at Audiobolics does, and he’s an electrical engineer on top of that. Sound is easily measurable, so if you want people to believe what you say, then prove it.
Cables can be configured to act like a filter just like those that filter water. Gene has been invited over. You are welcome as well. We've proven the differences in cables MANY times. All you have to do is show up and listen.
I truly believe that a good cable can keep noise out and provide enough clean juice when needed to your amp. Beyond that NO! I have lots of expensive equipment and I do have some good $50 Power cables. Not wasting a penny more for nothing. I watched this guys video on testing kspeaker cable as an antenna for a stereo. What bunk. the only thing he proved is that braided cable has such good inductive rejection it makes lousy antena wire. I studied Electronic Engineering at USC, Avionics in the US NAVY, Worked at Bell Labs, was a sentior member of the SME...
Personally, I think this is a costly manufactured solution to a trivial or virtually non existent issue. I must however confess, that my local ‘bricks & mortar’ hifi dealer was having a stock clearance sale. I picked up a bargain. A 5 feet ‘high end’ audiophile mains cable reduced from 5 thousand pounds to 5 hundred pounds. I fitted it to my 1800 spin speed automatic washing machine. The results were phenomenal. Now, when the machine has a full 10KG load and reaches it’s maximum spin speed of 1800, the noise it produces is infinitely more pleasant. The highs are smooth and polished and have lost any hint of sibilance or graininess. The mids are clear, natural and full bodied and the lows are so well controlled the need for room treatment or DSP have been negated. The machine no longer goes for a walk around my utility room, though I credit this to the girth and binding qualities of the cable, not it’s electrical properties. The downside. Because you know there is always compromises. My teenage daughter used to get a real thrill from sitting astride the machine when it reached maximum spin speed. That damned ‘high end’ audiophile cable has denied her that basic and simple pleasure. Enjoy the music.
I bought a really nice power cable for $5,000. It has beautiful plugs on both ends. Looks like carbon fiber. Male, and female. When I get some more money saved up I’m going to buy an amp, and some speakers.
When you do, be sure to introduce them through a gate or window for a few hours first. let them get used to each other's presence before allowing them to make direct contact, otherwise your investments will be wasted.
Hi Danny, “flat earther” here who wants to like your work on crossover designs and speaker upgrades, but I have also handled power supplies for computing measuring in the kilowatts and theater lighting arrays and sound systems where deploying arrays that pulled nearly 100 killowatts wasn’t out of the ordinary. I’ve used actual power conditioning equipment. I’ve also built countless power cables with numerous terminations for equipment that can pull up to 10KW at full power. I absolutely cannot condone anyone buying a $250 power cord. My 20 year old self would laugh, and my present-day near-40 year old self just feels sad. Here’s why: Consumer and prosumer audio equipment have switching designs to get from the unusable-for-anything-but-wall-sockets alternating current to direct current for use with anything inside an amp, DAC, preamp, etc. To go from AC to DC, electric power goes through a transformer, a rectifier, and several filtering and conditioning stages to smooth out variation and ripple, before it even touches anything else. (Never mind the fact that some integrated circuits have specific tolerances where they simply don’t work well, or just fail outright, if they run out of spec, so clean power delivery from the output stage of the power supply is a must.) Much like speaker wire, so long as the power cable is using the appropriate gauge for its length as to not melt and start a fire, it’s fine. I think, outside of the audiophile community, you would be (rightfully) laughed at if you said you purchased a $250 power cable… I can buy a whole 92%+ efficient 1KW power supply for that money, and it would come with a pennies-on-the-dollar, 2 meter long, 16-gauge C13 cable, and it work exactly as expected. A better power cable wouldn’t make it work any more efficiently or have more stable 12V or 5V output. Wouldn’t have to even buy one of those weirdo power conditioners either. (Again, I have dealt with real power conditioners for actual high load situations. They are not small and they are not quiet, and they belong nowhere near audiophile equipment.)
I can only agree with you on this one! Although I'll have to add an asterisk to the whole power supply and filtering thing, that being switching noise and the resulting EMF can introduce noise to high impedance signals between your components. However this is mainly an issue with really cheap gear, the kind with improper back EMF protection at it's power input, cheap high ESR caps, needlessly high input impedances, or any stupid but cost saving design measures. Cheap switching AC/DC power supplies and their DC(+ f>45kHz AC) power cables are notorious for this as well. You wouldn't ever use this professionally though, as you wouldn't plug in a power-LAN Adapter next to your mixing desk.
I would say - the converter can only do so much, so if AC is balanced in, the DC converted better, like a water filter, the more pollution in the more pollution out after it has been cleaned
recording (and apparently a flat-Earther) musician here...He gave a nice speech, but let's see several impartial listeners in a fair, double-blind A-B test correctly pick his cables five out of five times. he talks a good game but he needs to back it up.
Oh dear. Yes cables CAN make a difference - if there is insufficient gauge or poor connectors. But a $5.00 cable will have the necessary gauge and it is trivial to make a good connection. Spend your money on speakers. The reason this is so sad is that Danny is right up there when it comes to speakers - but now he descends to snake oil.
Agreed. I just can't believe that he has become so O.C.D about "F" ing cables. As you say, smart people know the differences and what types of cables are required for different applications, but honestly, in my 62 years I have never heard anyone bang on so much about this topic. Is this simply about trying to convince others that they must consult your opinion and purchase products from you? If not it sure as hell sounds that way and I have better things to do than to be indoctrinated by one persons opinion.
@@grahamserle7930 He isn’t OCD about cables lol. He’s sitting on tens of thousands of dollars of cable trying to profit of the audiofools. I’m not mad at all at the hustle. At this point “believers” deserve to be taken advantage of. I just hate how this latest venture takes the credibility out of his previous work. It would have been refreshing if he just went: “Cool looking cable, measure fine, see? You don’t need those 20k dollar cables, just get these affordable ones or even regular ones.” I would have respected that and I don’t mind spending a bit more on cool looking stuff. But here he’s describing magical listening experiences
@@TofumanFC3S Yeah, spot on. I don't have a problem with spending extra money on a better product if I know it will give me a better outcome. I'm not a tight arse but I'm not going to pay stupid money either for something that someone tries to tell me will transform my listening experience. I've been playing with this stuff for 50 years and those who know me think that I'm obsessed when it comes to achieving the best quality sound possible within a budget. Let's just enjoy the music shall we and leave the indoctrinated to believe that their deep pockets justified their supposedly better listening experience.
Any good power supply is supposed to provide isolation between the component and the mains. There is a case to be had for heavy gauge power cable for anything that draws a lot of current. But for your average 15-30W component, either the power supply isolates it from the mains, or it should be replaced. And quite frankly, you'll get more noise from the RF produced by a modern power supply located close to the signal path than you'll get from the mains. There's a good reason why computer PSUs are locked inside a fairly sturdy faraday cage, and audio component power supplies should be too (imo). I know a guy who hooked up his component stereo system to a UPS with isolation. What is fed into his system is a pure sine wave from batteries with perfect isolation from the mains. You can't get more "conditioned" than that, and there's no audible difference whatsoever. The UPS is a $400 component meant to protect his other $20,000 in components. Again, there is an argument to be had for heavy gauge power cable going to the amp (at least equal to the house wiring). But if the power supply of a 15-30W component cannot filter out noise from the mains, then it's a POS you should never have bought.
@@grahamserle7930 well he is so effective with his previous work because he has been able to show how he made sens of it all. Maybe he should just show clearly that he hasn't been able to pin-point the why. That would make it even more credible to me. But we can't say he's just in it for the money, there isn't sufficient proof.
As an Engineer I make a statement her: There is no difference between a normal functioning powercable and a “high-end” powercable … other than the amount of money that goes into the suppliers pocket.
You might want to revisit the school that issued you that degree and ask for a refund. Differences in the sound of power cables are supper easy to here.
@@dannyrichie9743 What school did you go to and what qualifications do you have? Can you reference measured data? Scientific, peer-validated studies? because the audio and electronics industries at large seem to be churning out a lot of misinformed people if you're correct.
@dannyrichie9743 True. Especially as "walifications" is not even a word. But knowledge and even experience can be quantified by repeated measurements. So do you have any?
14:03 I worked in big studio facilities around the world for many years and I've only seen regular 2$ IEC power cables on pro gears. Sometimes studios have regenerators or isolation transformers but it's only if they had no choice because of surges, line noises or big swings. The filtering stage of any pro audio gear should be sufficient to clean up the AC defects. If it's recorded like that in those studios, you'll get them on your home system anyway. Just open a 2000$ EQ rack and smile at those hair-thin oxydized internal connectors... Sorry but I'll let you hear this audio guru preaching how AMAZING vs AWFUL and LIFELESS it sounds when you plug a 40W amplifier with an industrial pure copper 4/0 AWG 100A power cable. Me on my side, I'll play some records in my modest room and just enjoy it for what it is, music. Peace
@@DynamicRockers The level of ignorance Dan displays in his videos prevents me from watching any more content. This guy is on another level. Makes no effort hiding his contempt for customers that don't want to buy his $1600 interconnects (you know....those interconnects made from $1.50 to $3.00 worth of parts).
Whatever component you buy is guaranteed by the manufacturer to meet all specs w/ the power cable they provide, so what’s the issue? What I’d be worried about is those heavy power cables ripping the receptacle out of the back of my amp.
'Truths' 🤣This entire page cracks me up. I need YOU to help me understand what sounds good, the same or different. I just can't think or hear! You amaze me~
Without blind tests, and ABing, it's nothing but guess-work. Going from "dark", to open and airy, takes several dB, across several octaves, for a 🌙/ 🌞 difference to be made, se-ve-ral decibels! If your [anyone's] power cable is doing that, there are serious issues going on, that should not be. Accommodation is what most people are hearing, closely tied to expectation bias. My 2c.
I would rephrase that as not expensive. For me expensive is when it is not worth the money. A lot of money does not have to be expensive, it is about perception. A good cable of a few hundred dollars that outperforms a cable that costs much more, is in my view not expensive. So I agree with Danny from this point of view because he does make the comparison.
You have always done a good job of supplying before/after testing of mods made to speakers. Where are the measurements for the mega hose cable vs the power cable supplied by the manufacturer? That would seem the obvious step to me considering prior approaches with speakers and upgrades.
@@mikeleventhal2093 Are you new to this channel? He takes speakers and measures them, tweaks them with improved components, makes adjustments, then measures them again to show they objectively measure better. Two, the ears are not the judges subjectively, your brain is, the ears just a path to the brain, and the brain highly subjective to bias. No one can tell the difference between power cords if using a correctly done blind testing protocol. They can tell the difference between speakers however, and interestingly, often prefer the less $ speaker when they can't see them. As this channel shows many times, some far less expensive speakers objectively test better than the high cost stuff. So again, I'd like to see some actual objective measurements from that power cord vs run of the mil and or legit blind testing, but I also know what the results will be...
@@willbrink Baloney, just your opinion and you are entitled to it. No one mentioned cost. My speakers are diy transmission lines, just tried a pair of JBL studio 580 and they were returned. Nothing but conjusted bass. For your info I build my first HiFi( mono) in 1957, so I've been around the block for many years with countless systems. And yes I now have some high frequency loss but can still hear up to 14k. The power cables I purchased were like 35. each and I started with the CD player( tube), next the preamp also tube, then the Stratos pw amp. The shielded cables made a huge difference with the CD and preamplifier; and almost none with the pw amp. End of story. Instead of being in denial, simply try for yourself; you just might be pleasently surprised.
@@mikeleventhal2093 I rest my case. Again, does sound like you follow this channel and how he goes about testing speakers. You are more focused on feelz and subjective bias then science and facts. If you think a power cord can sound different from another, by all means, get one and enjoy it. As the man said "there's a sucker born every minute"
A few hours into this series, and there is still not a shred of scientific evicence that support the idea that high end cables makes an audible difference. Meanwhile at the "other camp" some of the best measuring equippment is being used to very clearly disprove that these cables have any chance of making an audible impact. Anything that is possible to measure tells us that it doesnt matter. You are also suddenly doubling down on your opinion that blind listening tests are somehow not valid or necessary, which kind of tells us that you tried it and could not discern a difference.
I completely agree! Poor Amir is busy dispelling the myths propagated by name calling closet flat earthers. Also did you notice how his earlier videos talked about objective measurements but when that got disproved he suddenly switched to talking about "audible differences" Classic bait-and-switch.
I am new in this, but I think the best proof could be if he makes the worst conditions in a test room full of RF interference and such and test simple cable vs premium cable and show all that the simple cable act as Antenna and the premium cables act as Filter when he raise the volume knob to 100% while no music is playing, so we can hear if there is a noise with cheap cables and silence with premium cable.
what science ur talking about? were talking about audio systems, listen for yourself and find out, but first get a good system and set it up properly, then get familiar to it then try, the proof is in the listening
They are not proving anything. They are taking measurements and then theorizing if there will or will not be ab audible difference. That's not scientific evidence. That's just a belief. And we do blind listening comparisons over here all the time. That's how we confirm results. We listen.
i think double blind listening tests are the gold standard for this sort of thing, as knowing what's hooked up can influence how you feel about the sound. i'm sure cabling and the power source can make a difference, but for me at least there are just hard limits on the lengths i will go. tube connectors and good speaker cables seem reasonable, but i don't know about power cables. you would need a good power strip too
Going through all the effort of a double blind test just to learn your brain works like every other human brain and you do in fact not have an audiophile super power... Why would you want to do THAT?
@@Jako1987 that would never work. Can't have both setups identical. It's much simpler to have 1 room and 1 system and just have one guy switch the power cable, and see if the listeners can tell A from B. Doesn't even have to be double blind.
@@lmoelleb Yep... Sad thing about this video, makes you doubt every other video/claim! I mean sure, it's kinda fun to listen to, almost like you'd do for other supernatural stories; ghosts, living in a simulation, etc., but yeah... Kinda hurts the credibility.

Because it's nothing but bullshit. Worked in and around studios for 30 years. Abbey Road, Air etc. Places with 200k and up of custom speakers and the same on amplifiers in room designed by the best in business costing literal millions of dollars to create. ALL wired with the same Van Damme mutlicore and all connected with the power cables that came in the boxes of the kit. Studios can have 10's of miles of cables in them. No one pays ANY attention to this nonsense outside of audiofail worlds. Also why does he not measure these cables? He measures speakers to show the issues. Why not cables as well? Simple answer, measuring would show how full of shit he is on this topic. This is nothing more than a man selling snake oil products to gullible idiots. TH-cam is full of them.
@@ferociousmullet9287 Yup. I'm a studio guy too. Stock IECs are fine. We generally wire everything with Belden or Mogami. Neutrik connectors. It's all you need. The rest is bullshit for crazy people.
@@ferociousmullet9287 gullible idiots is strong language , but, in support I offer the many corvette owners who are now running around with the factory air filter on backwards because of an internet suggestion , offered without any proof of benefit.

That alone would cut down on a lot of the snake oil people peddle.
If you're filtering out HF/VHF noise out of AC mains, how is "too much filtering/conditioning" a thing? Unless the filter designers are chopping the sine wave at 50/60hz. I mean, isn't that just a bad conditioner design? Show me AC mains straight to a scope, and then show the scope on the end of the fancy cable/conditioner/regenerator. THAT should be your selling point.
@Douglas Blake mate you completly missed his point. he rightly asks what the problem could be about filtering too much. Video says it makes the sound dull, well can you explain why?? that would be a selling point!
@Douglas Blake A simple cap can remove some RF noise. It creates a first order style filter. So it just removes some of it. And on the interconnects it would easily become a high pass filter. So no, it doesn't work on interconnects.
The old cable controversy at it once again. Let me ask you a question. If the power cable makes such a difference then you should be able to measure it, right? Here's the problem, you cannot as there are no differences between snake oil power cables vs the ones that came with your components. Furthermore, if, and that's a HUGE if, there was a difference, even a small one, don't you think that major players such as McIntosh, Musical Fidelity, Bryston, Rega, and Naim just to name a few, would offer a choice in power cables? They do not! Why? Because they know full well that it does not make a difference. Also, if you call any of those manufacturers, they will all tell you to stick with what the equipment came with. There's no need to buy cables that cost an arm and a leg. I can just imagine going to McIntosh or Bryston and tell them that their $10, 000 amps and preamps would sound so much better with a better choice of power cable. You guys manufacture and test your equipment up to wazoo but clearly, you need to fire the one suggesting that a $20.00 power cable is enough...right? That with a $250.00 dollar cable, your equipment would be so much better? I wonder what their answer would be? By the way, let's not forget the blind test. Funny how not one of the so called pro's selling those cables, refuses to participate in blind tests. I've challenged someone who makes speaker reviews online and in magazines, to blind test 3 speakers ranging from $4000 up to $10,000 and compare the result with previous reviews of his. Guess what? He refused! It's easy to sit down and make reviews based on high quality and expensive equipment when you are aware of the brands but not so much when you are in the dark. By the way, all REL manual says 'Only use the power cord supplied'.
@@cameronkrause4712, right! I remember now how they sold out to please those who believe it makes a difference. Quite amusing when I think about it. Even funnier when people pay big bucks for something that makes no difference in sound. th-cam.com/video/Rgun97VK7y8/w-d-xo.html
I absolutely agree with you to a point. (I tend to think this is snake oil, but I do have an open mind despite it going against all known measurements.) Danny claims that this must be "listened to" instead of measured. Maybe, he has a point - maybe we don't have things to measure it? But, a simple blind listening test, could confirm he has something, or not... And if there is something, the test can be made more and more perfect with scientific, peer reviewed ideas on how to improve the testing. But, there has been NOTHING so far! Is that not the very way that flat earthers have "proven" their theory?" This, is insulting to science. I'm not saying he is wrong. If the effect and differences are as great as he claims, it should easily be able to be tested, verified, repeated, etc. While the first "evidence" may not be perfect (i.e. not a double blind, controlled ABX test...) I'd just like to see 4 out of 5 people state which cable is which since it's "so easily audible." Danny does a lot of things great - I have learned a lot from him for certain things - but, he can't go on saying that everyone else is wrong, without presenting actual evidence for the claims that he makes. It can't be measured, only heard? Fine! Setup a decent listening test and present evidence! Until then, he's the one on the side of the flat earthers denying all other measurements.
@@FEGTTTSDH Rega has a jazzed-up cable for the Osiris integrated amp. It's not an option. In their own words: "A Rega designed fully shielded, high quality, high current capacity mains lead is included." Apart from being fully shielded and slightly higher current, how does that make a difference with other cords? Rega does not state a single word about a sound improvement which is normal as if they did, then they would need to offer such a power cable as an option to other amps, right? Jazzing up a cable for a $10,000 integrated amp is more for show than anything else.
I am oriented to science and facts. I thought there is no way a short power cable can make a difference. I also read many articles expounding the virtues of power conditioners. I experimented with DIY power conditioners and found exactly what Danny describes. A little can help, and too much can kill the system. Isolation transformers slightly reduced sound quality. Inductors, even a small amount could kill the sound stage and make the sound dull and lifeless. Power cables are where I was shocked. I found a substantial difference in sound. I make my own, and they are a solid improvement in bass, sound stage etc. I used some DIY recipes from VH Audio cables with 10gauge wire. Sounds terrific. I put minor amounts of filtering in the distribution box using caps and also built a DC block circuit to avoid transformers from buzzing and saturating. This was all I need. There is only a couple feet between the conditioner/distribution box and the electronics. I also built an 8 foot cord to go from the wall to the distribution box. I also put a ferret clamp on the safety ground at each consumer. An inductor or a ferret clamp is not good on the power wires. I cannot explain any of this other than the notion of an appropriate amount of filtering. It could also be that the caps act as a volt/var circuit. I live in a large city and there is a ton of noise in local distribution including RF over power. My house is full of LED lights, dimmers and switch mode power supplies. There are several computers plugged in and powered at any time. Every house on the street has the same. We all have a plethora of radio antennas for wifi, cellular, garage doors and home automation. Somehow these power tweaks that cost me nothing helps my system work well.
@@doctorfuzzzdirtbox With all due respect, feel free to do your own research. I have reported my circumstances and subjective opinion. Do with it what you wish. IMHO, there has been very little scientific study of the subject so there will be very little to be found. No one needs these things. An amp or a DAC will function safely if fed power by any UL approved power cord. But as I report, I and many others have been surprised that different power cords do in fact make a substantial difference in the sound in well resolved systems where low level detail is appreciated.
@@user-od9iz9cv1w most of the people commenting on here are just parroting what others have said without even trying a different power cord. They keep making the same stupid comment that is the resistance is the same then it must sound the same. Well half of them are probably relying on someone else's measurements to make this statement, or don't have high enough quality testing gear to see a difference. Because if your equipment is sensitive enough no two cables should ever be the same. Using that same theory if an open baffle speaker and a boxed speaker measured exactly the same the should sound identical. Yet they sound nothing alike. Why is that? Because half the time people are measuring the wrong thing. How does resistance of a wire tell you how well that cable is insulated if you have it near some noisy equipment?
@DodgyBrothersEngineering As an audio engineer of 20+ years, I just want to know how I can find these results for myself because a speaker, with varying design cannot measure the same in all metrics. So neither can a power cable. As an engineer, I don't believe in my own ears. Psychoacoustic fundamentals can prove that our brains can very easily lie to us. Especially when cognitive bias is involved. So we need hard data to see through the mist.
Sorry, but if the bass response of your power amplifier changes because of a different power cable, you should have a serious conversation with the manufacturer of that power amplifier. A quality amplifier must have quality internal voltage circuitry that is independent of noise, RF reception and whatever the power line does. Period. If equipment sells as "high-end" but you can hear the neighbors washing machine switch on or a Russian opera station via the power supply, the equipment is not high-end. Somebody screwed up in the design. Audio equipment should not be designed to only operate correctly in a military-grade Faraday cage listening room with filtered power supply.
@@MrsZambezi Of coarse it can. You have no idea what you are talking about. Maybe this will help: shunyata.com/2019/07/11/power-cord-measurements-revolutionary-dtcd-analysis/
@@GRResearch My oven is able to use 2900 Watts for as long as a recipe takes. The power cord that came with the oven can take that, does not become warm and probably costs about 10 or 15 bucks. Any power cord that can continuously handle a pretty energy-hungry household appliance that uses, say, the peak power of your amp divided by its efficiency, is good enough and does not have to be expensive. The power circuitry should take care of smoothing and buffering. If you hear the difference between two cables that meet the above criteria: that's a flaw in the amp concerning design, part quality or age (capacitors come to mind). If your amp comes with a cable that does not meet the above criteria: buy another brand amp. Apparently they don't take things seriously. Or use the cord of your oven ;-)
@@GRResearch Research does not always means science or relevant to the application.First they talk about a "representative equipment sample" but do not specify what "segment" of the market it should represent, for example the "audiophile" market segment. Second, the actual used equipment is not mentioned, so there is no way to verify if the sample is indeed representative. Third, they mention "a variety of product" inside the equipment sample, but there is no method mentioned how the result are aggregated to produce the graphics shown. The previous leads to an experiment that is unclear about its scope, its methods and about its sample-set (the equipment). This means the experiment cannot be reproduced and the results cannot be verified. The result is that the experiment cannot qualify as "scientific". However, even if the experiment was scientific, the maximum scope of the result is _the sample of equipment used._ As long as we don't know that sample, we cannot draw conclusions. And even if we would know the exact equipment, we have to make the assumption that the drop in voltage/current has a noticeable effect on the desired behaviour of the equipment, for example the accuracy of audio signal reproduction. _For the sake of argument_ I will assume that this deviation from desired behaviour is a fact, event though it is highly dependent on the circuitry used. Now let's assume that the article relates to the audiophile market segment. Because we have assumed that the measured behaviour has a noticeable effect on the desired behaviour of the equipment - in this case audio reproduction accuracy - audiophile equipment MUST have a good power supply. What is a good power supply? A good power supply perfectly separates the characteristics from your wall-socket and the characteristics that the internal circuitry of you audiovisual sees. Whatever power characteristics come in, as long as it is "enough", the internal circuitry should see an almost perfect voltage-source: a voltage-source delivers a constant voltage that is independent of the drawn current. In yet other words: disturbances that enter the power supply should be invisible at the other end. Naturally, there are theoretical limits. If the average amount of power that the power supply can get is smaller than the average power it must supply, things break. But the power supply should definitely hoard enough energy to cope with (short) bursts of current demand at a constant voltage. The used 50 microseconds in the experiment should be peanuts and should _definitely_ not be passed on to the power cord directly! Outcomes The first outcome from the experiment is that the used power supply of the graphics _is not a good power supply_ at all. It does not buffer enough energy to support bursts and quickly becomes largely dependent on the input power. This will make the circuitry that it feeds see disturbances like power limitations, zero-crossings (wall-sockets are AC and when voltage difference is zero you cannot draw current) and potentially for other fluctuations that are caused by other equipment on the line or the power company. Not good. The second outcome is that this equipment should never qualify as audiophile, unless it is pampered with laboratory-grade power cords and sanitized power (which does not remove some of the mentioned problems). A consumer should not have to depend on that! And if the power supply is that bad, that doesn't bode well for other design decisions made in the equipment. The third outcome is that the manufacturer of the equipment gave a bad power cord. The reason is that if the cable makes a difference, it is very under-dimensioned, possibly leading to even more degradation caused by getting warm or even causing a fire hazard. It can also be that this experiment used the same "representable" cable for all measurements, but there is no way to know. By the way, if your amplifier needs a power cable that can deliver more power than your wall-socket is rated at, you can also get in trouble with fast fuses. Your equipment _should not_ depend on that. See the story about power supplies. A cable that can supply an oven or washing machine without a noticeable increase in temperature, is generally fine. Conclusion If you do not know the quality of your equipment, you can borrow a cable from a heavy household appliance like an oven or a washing machine to see if it helps. If it helps, you should not consider your audio equipment as "audiophile" as its power supply can't make that happen. Because certain problems that are inherent to your power supply cannot be fixed with a cable unless you pamper your equipment with laboratory-grade power cleaning and cords, but you shouldn't have depend on that as a consumer. Naturally, you can then use an expensive cable if that makes you happy. Good audiophile equipment comes with a good power supply and a good enough cable. If swapping the cable for a better one helps, consider asking your money back for both the cable _and_ the equipment.
@@GRResearch The copper distribution wire going from your electrical panel to the outlet you plug your stereo into is 14/2 CU where I am from and as well in the US, typically protected with a 15Amp breaker. The attachment you provide shows a voltage and amperage drop in the OEM supplied power cord which is entirely possible, however it also means that I can replace the OEM supplied power cord with 14or12/or10/2 CU Romex and install my own adapter ends solving both problems the OEM cord created and use that to power my components for a cost of about $10 Home Depot prices. You can convince me I need the better cord you will have a much harder time getting me to spend $500 on CU wire at 1.5M in length. You can run 14K gold wire from the outlet to the stereo unit it wont sound any better than the wire does that is supplying the plug you tap into. We are not talking about line filters here just simple wiring. I was in electrical distribution for thirty years and that much I know for certain.
Hi Michael I have not heard your system under day or night-time conditions nor do I know your EV power system, but in the daytime you are charging batteries and running an inverter (assuming 110V audio operation). In the nighttime you are still running the inverter but not charging. Don't you rather think it is the charger imposing its noise on the supply? Best regards, Rob
@@RobWhittlestone, here in Hellinois we do not have battery-backed solar systems. The system either makes power that is consumed or pushed back to the grid. No battery storage. When the panels are not producing, I am back on the grid.
@@michaeltuohy1249 Oh very interesting! Thank you for your helping me understand your configuration! Now I understand your theory: sounds plausible to me; I agree with you.
If you can hear the difference between power cables, then the PS section in your amplifier sucks ass... ;-). It's supposed to convert everything it sees at the AC side to clean DC to power the amplification circuitry...
If u like, some can kill ur Amp only with power cables on ur own grid. Then call 9/11 and ask Washington to make a 5000 pages report to explain what happened to your Amp. We'll call that the 9/11 Kill my Amp official report where no cable was involved.
@@davidleathers6406 Thx ! Was a pleasure to deliver. Well this is real : I almost destroyed a pair of 3150 NAD transformers with a bi-wiring direct from the grid. It almost started to boil like a volcano ! No islamistes state sponsored involved, only me. Mysteries, mysteries. Cheers.
Why do these audiophile power cable guys never suggest using a proper, big UPS? They could condition the power how they wanted then - exact frequency and voltage, filter out the RF....
I so of agree, but how can you over filter it? If you manage to remove all ‘interference’ from the cable you have done just that. It implies some noise is beneficial.
How does the "sound stage open up" when stereophonic spatial differences require stereo channel level or time differences? How does the power cord produce stereo channel level or time differences in identical and independent audio signal paths?
solid wire is always best for ac stuff, just wondering about stereo / audio , i think stranded is used for flexibility .. Just a thought , wondering if you have tried solid to stranded. I know it's not that flexible but for ac is best...most house wiring is 14awg to all wall plugs so would it be better to wire amp/ receiver with 10 awg solid copper wire ??? just wondering if you tried that against the 12ga stranded cables,,,
If these cables do everything said of them, why don't the equipment manufactures integrate them into the equipment and do away with the plug/socket which is apparently another item that introduces distortion.
We should take into consideration the wires in the house and in the streets, too. I mean, what difference could possibly make, if you change only 2 meters of the total length of kilometers all the way down to the nearest transformer or powerplant? The wires of the main grid of a normal house is built based on general purposes in mind, not audiophile concepts. You might have a noisy, far from perfect sinus waveform of the mains, but can the 2 meter long power cable eliminate this noise? Should the power supply circuit of an amplifier/deck/etc. get rid of these inperfections and provide a stable DC voltage for the audio circuitry? Does the lack of noise make a wide soundstage? Does the effect of the power cable will enrich the signal with something that is not present in the original source (e.g. more treble)? And what about the less than perfect cables and other conductive materials inside the amplifier/deck/tuner/etc.? So, there is a long and complex system of wires from the powerplant to all the way to the loudspeakers. What difference could it make if you change 2 meters out of 1 km? And if it works with 2 meters, can we do it by only 5 cm long professional power cable, too? It would be cheap enough.
Actually in japan some audiophiles they do change all cables and establish a seperate line from the transformer to their home and listening room . You do not need to go that far but I truely understand the idear . ( In the place where I live I would help not just my audio systems but all other electronics too ) I have a small home studio and the worst electric system in house / street as you can get . No protection at all from main transformer in street / alley to the house and only two 30A fuses after the breaker . The breaker is worse than ww2 , ww1 circuit breakers where you flip the big handle . Nothing to protect or filter anything , absolute NO protection and zerro grounding . No wires are wired same way so outlets have hot and neutral flipped in some and not in others . I can tell you that those few feet from the wall outlet do make a big difference what cable you use . I have made my own grounding and what type of cables I use DO make a big difference . There is so much noise on the whole electric system from all small local business and shops and even other homes aircondition systems ect . By use power condition and the right cables I can get noise down . It doesnt have to be expensive cables , just cables there is isolated and act as a filter with good insulation and shielding against noise . Using standard cables is a big no no here because you drown in noise . ( I live in an alley in Philippines where all electric wires is like big spagetti hanging on big poles )
As a polymer technologist who did his PhD on Polyethylene, I'm interested to know what kind of changes can occur with Polyethylene at room temperature in a so called burn in phase that would affect its electrical insulation properties. Polyethylene is a semi crystalline polymer and crystallises as it cools from the molten state at between 120 - 135 deg C depending on its polymer structure. the amorphous phase between the crystallites is above its glass transition point and is in the rubbery state and will experience some relaxation of the built in stresses within the material caused by its rapid cooling from the melt state 9during the wire coating extrusion process. but whether a bit of molecular relaxation in a non polar polymer insulator would or could affect sound, remains to be seen, or heard... as a LINN Owner, arent we used to being flat earthers?

You know, it’s remarkable that Danny judges speakers on frequency response, phase and resonance graphs (you know, science) alone, with no regard to how it sounds, then tells us that you can’t measure the difference between cables and that we should trust our ears. I think Danny is broken. Someone please check his capacitors
I think you havn't watched his videos at all. He do combine resonance graphs with listening. That's what he is doing for a living among other things. And if he can't find a cost-effective way of upgrading the speakers he gets in for testing, he will tell the customer to leave out the costly procedure of improving the speakers. Even better, to upgrade and buy a better speaker. Some speakers can't be improved for a low cost. Do start to watch all his videos from the very beginning and you will get what kind of interesting improvements he can help people out with. You might learn something as well...
@@theklipschcave5593 The trouble with Danny lately is that he uses strictly measurements - actual science - for "improving" speakers without regard to how they sound (many sound great to begin with), sells improvement kits whose results you may actually hate, then recommends cables (he also sells) whose effects he can't measure, but assures you that they make a difference in sound. If you are not happy with your speaker, get a better one. Don't expect a difference if you wave a magic wand over yours with nebulous cable claims. Then again, ignorance is surely bliss. Danny surely knows what’s he’s doing. That’s what bugs me. He’s selling! I know electrical theory and his little inductor trick was just that - a trick. It had no bearing on whether one cable is better than another. Yet people like you and many others have taken his word as gospel and more than a few have spent their hard earned money on vaporware and promises.
@@HipocratesAG Great point. My ears are even worse, I'm sure, but Danny is probably topping out at about 10kHz these days. Maybe he should hire his wife as a subject. Then again, she might want those earrings and just say what sells cables.
@@HipocratesAG Exactly! By the time guys (and it is always guys) can buy expensive cables their ears have degraded from age or their work. And there is no difference in cables anyways,
I use a Furutech pure transmission AG Power Line Receptacle Filter do you think I still have to upgrade to a better power cord? Use the Filter or go directly to the wall electric socket? Yes, I use an integrated Power D amp and you mention it would be better to use a better power cord direct to the Wall socket? What about a CD player? Does the power filter help or not and is it necessary to upgrade to a new power cord? Would appreciate your comment
I like your speaker upgrade videos because you provide graphs and data showing how the frequency response etc have changed. If these power cables make the sort of audible difference you describe then where are the measurements that show the sound out the speakers has changed when you swap between standard and premium cables?
Don't hold your breath waiting for the data. It would be easy to do the measurement since he's done them before. It's not hard to guess why it wasn't done or why it was done but not presented here.
Yes, he has said in at least one video on YT he doesn’t need to listen to speakers to improve them. He just uses the FR graphs to show his improvements. But for cables it’s the opposite (?) You have to hear them, not measure, apparently. 🤷🏻♂️
.... and there is a return option if it does nothing for your system. If you have a nice system, why not try it out? It is free to try. The worst thing that can possibly happen to you is that you hear a difference and then you covert to the dark side. But the worst thing about learning that cables can make a difference is then your stuck; forced to listen to all of the bobos that troll this topic just to tell people how stupid they are. Just know, It will probably not work if your system is not capable of a highly resolving sound. nor on most class D amps according to Danny. Again, it's free to try.
@@fhester44 I'm just going to say it blunt, all "audiophile" cables and premium cables are snake oil. They do not measure any different than generic cables and they make literally no difference. In fact, sometimes they are worse, such as the cables with battery packs (Audioquest Thunderbird) because they add capacitance which obviously affects signal integrity. Anyone who tries to convince you different than this is either trying to sell you snake oil, or has deluded themselves into thinking it makes a difference.
One factor that is ALWAYS overlooked is - how good are your ears? By the time most folks can afford a top end system their ears will have a HF roll - off that appears to make system sound dull, one ear may have been slightly more affected than the other which can blur the sound stage, and due to the wear and tear of the ears mechanics the dynamic range suffers, ie. a bit deaf so the quiet parts are too quiet so you turn it up, then the loud parts are too loud 'cos the ear cannot handle the sound pressure dynamics and it sounds distorted. You could spend a million bucks on the technically perfect system and it will sound poor if you don't look after your ears. Perhaps instead of spending on power cords get your ears tested!
And that is a fair question... What I used to say to my mother who had a bone defect in both of her ears, and had both of the bones in her ears replaced with a silver wire was... The worse your hearing, the clearer it needs to be. In later life mum got hearing aids to try and help her hear better, but she didn't really need them. The operation reduced her hearing to a very narrow band of frequencies. She could hear between 3000 and 5000hz OK, but outside of that she struggled. So it was often harder for her to hear what I was saying than it was for one of my sisters who talk in a higher frequency range (and volume they all yell when they talk). But if I took mum out of the echoing kitchen into a bedroom where there is carpet, and spoke to her standing right in front of her, she could hear me perfectly without needing to raise my voice. Nothing changed except the clarity in which she could hear me.
Getting your ears tested won't affect what you can/cannot hear. Once your hearing deteriorates, there's no going back. Hearing protection should be aggressively enforced when people are young. It's impossible and impractical. Orchestra musicians are subject to very loud sounds, but they're not wearing hearing protection. Many members in groups with amplifiers use them, and many wear in ear monitors to be able to hear the whole band. Audience members should be wearing ear protection. Loud concerts sound better with ear plugs.
@@dannyrichie9743 Its simple, if the power cable makes a discernible difference in the sound (which is his whole argument) - then show before and after charts. Are you implying that we will hear a difference but it won't show in the charts?
@@dannyrichie9743 So you are saying that the sound will change but it is not measurable. Can you provide an example? We are talking about changing just the power cable. At the wall, inside the house, the electricity comes from a 14 gauge wire. We aren't talking about power conditioners or giant caps or batteries being added, or specialty taps being run from the panel. We are talking about a common house 14 gauge wire that feeds the power cable. The whole argument is that changing the power cable will change the sound. But GR-Research has provided no proof, neither have you. Just heresay, "because I say so". Now, if you were to tell me that there was a 120 amp run from the panel, 10 gauge, and then a power conditioner - that would power the components more linearly, because the power is on constant tap and there is a lot of it. In the valve world, some people actually like under-powering their amps to get the brown sound. This happens as well with keyboards and guitar pedals. And, there is absolutely a measurable sound change. But, we are talking about solid state that is designed to work with that shitty common house outlet. If the output difference is not measurable, then its psychological. Please provide examples.
@@aportilla007 No problem. The geometry of the cable changes the capacitance and inductance of the cable so that it acts as a filter for higher frequency ranges. So it is more resistive to the upper ranges blocking a level of noise out. And we can easily measure changes in capacitance and inductance. The audible effect is quite apparent. Measuring the audible effect is not at all easy. It is a lot tougher to measure what is not there opposed to what is there.
A lot of people commenting on Danny but very few who actually take up the invitation to put his assertion to the test. For me, I listen to the fellow who do audio experiments on a regular basis
Have u scoped it on a spectrum analyzer, and network analyzer? Curious to know line noise and mains/inverter impedance in each case. Maybe attribute to maximum power transfer from mains to amp, and cleanliness.
The thing to remember is the diminishing rate of return. MOST people will reap the most NOTICEABLE benefit with a good Filter/Protection strip and "shielded hospital grade" power cords. That means you do not need a $1000 "audiophile" power conditioner, you will be just fine with a $100 Furman or Triplite. As far as the AC cable, you would have to be in a VERY electrically noisy room (like a trade show or computer room) to really need it, but if you need it A shielded Hospital grade power cable (that has a grounded outer shield is all you need). So again... a $10 hospital grade AC cable will sound the same as some snake skin $200 AC cable.
What does 'hospital grade' change over a regular power cable? Maybe it's a lesser evil than full blown snakeoil cables, but they certainly won't sound any different than any $2 computer power cable...
@@literalghost929 hospital grade is a thicker conductor and an EXTRA shield that is intended to reduce emi rfi signals that may be flowing in electricity. They use them to make sure those signals do NOT interfere with medical machines and meters.
@@franciscoortiz6980 That won't change anything. Check out Audio Science Review "GR Research B24 AC Cable Review: Does it Make an Audible Difference?", he compares a cheapo cable and there's absolutely no difference... And it's perfectly logical, the electricity from the outlet/cable passes through a power supply: Transformer, caps, diodes, etc., there's no way any 'signal'/noise goes through the PS. Btw, HP grade cords typically aren't shielded.

Try Oneac line conditioner. We used them when we sold POS equipment. They are hooked up to every machine in a hospital. Check it out. Great and not expensive.

@@DanielC__ exactly. What they charge for these cables is truly obnoxious. It shows just how gullible "audiophiles" are. (These are the same people who will pay hundreds on cable elevators). It's amazing - the power of suggestion is a mighty powerful thing. It's psychosomatic. I've done the listening tests on expensive systems and midfi. I could not tell the difference with the normal factory power cable and the ridiculously over priced crap.
@@bunk-bn9eo Agreed. Early in my career I spent 6 yrs selling Hi-Fi gear in a few shops. There is plenty of good sounding gear but it’s so subjective. Having literally done or been a part of thousands of A vs B vs C equipment demos there is one over riding result: people buy with their eyes. The people that identified themselves as “ audiophiles” were the most entertaining with blind tests. We could A B gear that was identical multiple times, they couldn’t tell. We hid standard grade speaker wire, interconnects in fake larger casings…the big cables always sounded better to them. We had special large speaker cabinets that we could insert much smaller speakers inside. People either loved the awesome bass response from the “big” speaker or others had a bias towards bass and thought big speakers were to boomy. Yet, we could play identical small speaker beside fake speaker and it would sound more refined not boomy. If we showed them a fake inflated price tag on gear, they would pick the “expensive” gear most times. We did fully disclose these testing “tricks” to customers to show them sound is subjective. If you like it, get it.
Can I interest you in some audiophile paint? “high Frequency White” is particularly useful in countering the dreaded “Dark Sound” caused by too much filtering. Only $999 a can. Don’t knock it if you have not tried it.
Do you offer a discount for bulk buying? Do you find that Matt or gloss is more effective? How many coats do you have to apply, before the ubiquitous laws of diminishing returns rear their ugly bonce? If I were to put a couple of coats on the inside panels of my speaker cabinets, would this make them more inert and work out far less expensive than a couple of sheets of Danny’s ‘no res’?👍🍻
You should look into Shun Mooks products. You'll die laughing. He creates a wazoo pendulum made of apingo ebony wood dipped in the swamps of Africa that spins and changes the energy in your hi-fi gear or so he says to sound better.
So what might you recommend for a hybrid system, used for DJing, and music recordings? I'm in a town house and in place alone, I have IT gear, DJ gear, studio gear, and of course my TV/soundbar. I do have an APC UPS system and I run most things from a 4 way junction box. My AC has it's own outlet and I do not run it while I am recording. I also have live instruments in the room, and my recording gear amps are AB power amps/ recievers. We do have occasional brownouts as well.I am doing a complete renovation in here so I want some suggestions.
You can get much better sound from using a good RCA cable that filters out noise. The problem with XLR's is they they won't filter out noise already on the line. They only filter out the noise they pick up as being an antenna. So they pass whatever noise was there to begin with without adding more.
If my power is run from fuse box to wall outlet and it's not sheilded just 3 conductor solid 14gauge romex, How do I get greater performance from the outlet to the equipment with this massive cable? Maybe if all the cable had similar build and gauge but you can't correct garbage in garbage out with some magic in between.
like any other solution to any problem, first the problem must be understood and identified. then one must figure out how to effect correction to the problem. I have yet to hear anybody identify what the problem is with the factory supplied wire to the wall, and what can be done to correct it. I hear , "OEM wire bad, expensive wire better, with never a solid reason or an identifiable defect about why change is needed . Unless you like to spend money just because you can. The correction the wire sellers speak of is to spend money, cross your fingers and listen, maybe you will hear an improvement, they can't say, disregarding the known fallibility of human hearing , while simultaneously failing to identify the problematic mechanical system in the wire that needs to be corrected in the first place , with the more costly , fancier wire.
I change the power cable on my Delta Unisaw Table saw today , It cuts faster, smoother , quieter, Less vibration on the cast-iron top. I would like to do a double blind test but I am scared , I’ll cut my fingers off 🤔
I changed it on my kettle. I could swear that’s it comes to the boil far more quickly and is slightly definitely maybe quieter and the water tastes cleaner. It probably cures COVID-19 too.
I have a friend that works at the CERN. He was able to put some of my old cheap power cables in the most powerful particle accelerator in the world on an off shift. You would not be able to believe the difference it made to the sound! It now funnels muons, pions and quarks and changed the subatomic structure of the wire itself. Anyone want to buy it for $10K?
Great information about how power conditioning can affect an audio system. It's definitely necessary. I have 2 test cases: 1) What if the amplifier/CD player etc. has an inbuilt power cable? Meaning it's soldered onto the board and goes directly to the power transformer? 2) What if you buy some audio gear and it comes with a removable power cable? is it junk? do you throw it away?! Might this also be necessary for other electronics? Let us assume you have a power conditioner. It's going to protect all of your audio gear and feed it clean power. IMO, hospital-grade power cables are where it's at. They are made to NEMA 5 - 15P specifications; which would also ensure ideal performance with sensitive medical equipment. If we have high-end audio gear that may be sensitive to drops or peaks in power, these cables should work fine. That's been my experience...
@@ericgardner5548 i have to disagree. As a matter fact, audio amplifiers with soldered (hardwired) power cables won't benefit from a new power cable. But any other component that uses an external power supply will.
a voltage stabilizer is the only thing about this that is not snake oil. this is the most ridiculous debate ever. unless you condition or PHYSICALLY ALTER THE POWER nothing changes, assuming the wires are equal to or greater conductance than the outlet itself, or unless you are replacing a bad cable oxidized or damaged (internally) with a good one. i have blind tested people with pin drop hearing and you can really mess with them and make them think the standard copper cable is the upgraded one. simply its a placebo and i am SHOCKED that this video was made by a man i thought was smarter than this. but then again he does use the same exact capacitor series when he upgrades everyone speaker, so there is bias involved too. i have done so so much extensive testing on different capacitors with different tweeters and you just can not use the same cap on every tweeter made to get the best result. hes nice to listen to and has lots of great input, but in the end he has convinced himself that one size fits all, and now he joined the cable placebo. again, this is not talking about using crap cables and upgrading them to ones that match the output and length, this is just silly silly placebo effect. its simple: its a good wire or its not, the end. anything past that is about the equipment itself and yes voltage stabilization so the circuits do not dip up and down in power in/out
@DJ FireStorm ever heard of a power transformer inside of an audio amplifier? It takes care of voltage. A power conditioner simply filters electricity that is compromised by noise. Power cables can make a difference - specifically, with Class A amplifiers that are inefficient by design and require power on demand to perform well. Just use 2 awg thicker than the standard cord, and you should be fine. I am not suggesting power cables that cost many hundreds or thousands of dollars.
Am I the only one who sees the irony of a science sceptic calling science and engineering principled people 'flat Earth guys?' Dude, Danny, you're the flat-Earther!
No, you missed the point. The guys claiming that they are using science and engineering principles are using them to form a theory. That's not science. To answer a question about audibility requires listening to get the answer.
i built a cable using some lower priced connectors and supra cable (LORAD 3X2.5 BLUE B50) and plugged it in to my marantz 8012. I have a full atmos setup.... what I noticed asap was the noise floor dropped by a ton... honestly the noise floor getting quieter, let the audio play 'more' -> i could add adjectives but sharing what happened effectively without explaining how I heard more from the music is the best way to say there is a difference. your cables in a system can act as antennas as Dany said, and that supra cable I built is cheap proof of that. Probably those oscilator people could come over to my place and make some measurements :-)
Can you please do a video on power cable length ....I've always been told that 5ft was optimal ...but that shorter or longer will indeed sound different. Would like your perspective
Hi, thanks for all your informative videos. A couple of Questions: 1: If braided speaker wire works to filter out RF, which it does.( Owned Kimber Kable for nearly 12 years). Could Braided Power cables do the same thing? 2: Have you ever tested the older Polk Audio RTi As series of speakers for us poor Audiophiles? i have Polk Audio Rti A7. Thanks
@@doctorfuzzzdirtbox With all due respect, do some more research on Kimber and why he braided his cable in the first place or you need to get your ears checked.
@@Rob-un6pj I've since understood the different references of braiding. Many cables are marketed as "braided" having an outer layer of cloth - primarily for aesthetics. It clear now that we're talking about braiding the cores themselves and I understand the principals of this. How Danny couldn't decifer this and point me in the right direction is now what baffles me.
Alternating current can be "dirty" due to modern electronic devices, vacuum cleaners, microwaves, chargers, florescent lights, dimmers etc etc. The only real thing that any decent power cord might need is a thicker gauge. You see this is why it's always "some guy from Canada with some forgettable product" that gets mentioned along with the anecdotal bedtime stories. Because there are no disinterested parties in the audio industry. The amount of backdoor excuses baked into the cable claims are there for a reason. "Like the fact that there's no ONE SIZE FITS ALL". Because if it was measurable and substantial it could be patented!!! Otherwise you will just have to trust the fact that it opens up the whatchamacallit and deepens the doohickey and smells so much better than lesser power cables. Extraordinary claims require extraordinary evidence. But they will just make you think that you simply cannot hear it. What a shame to be you. If only you had good ears and a fat wallet, then all of your sonic dreams could come true.
So if evidence is to be believed the earth is not flat. Yet here we have someone telling us people are flat earthers because they want some evidence! Strange hypocrisy going on.
My day job includes recording relatively quiet high frequency bat echolocation calls in the 20 kHz to 70 kHz range, at wind turbines operating in low to moderate breezes (under 12 mph winds). I had an electronics engineer design a steep RLC filter for the 12 volt DC fully regulated supply powering the detectors. He is very familiar with the recording device, the power supply, and the experimental setup, and he tested it in the lab and said it provided excellent filtering and should reduce electronic noise in the detector, so I should get good recordings. I placed 6 units in 6 wind turbines and operated them for 2 nights. There was so much noise the recordings were unusable. We discussed this a length and he swore it was impossible for so much noise to enter the detector through the power supply and filter. After lots of additional R&D I determined noise was entering the recording device through the 12 V DC cable shield, so I instead switched to simple 2 conductor cable, added 2 ferrites to the 12 DC supply and it reduced the noise level enough to get usable data. The difference was 100% unusable versus usable recordings. My second comment is that the sound improvement from good speaker cables and powerline filtering is not in the loud parts of the music. It is in the quiet parts, the room reverberations, the subtle sounds around the instruments and music. Probably less than 0.3 volt audio signals at the speakers. So distortion compared to full output is not what we're talking about, rather it is noise compared to 0.2% of full output. That's the kind of sound I record with bat echolocation calls, very quiet sounds occurring in higher noise fields. The takeaway is unless you really analyze all noise pathways and reduce the less obvious ones in the setup in question, you may not get the good results you desire. So my suggetion is to try good speaker cables and good power cords in a high resolution system, before dismissing it out of hand because there are likely other pathways for noise to get into the music's quieter passages.
@@mikeazeka1753 Great comment. Gives an insight into some of the subtleties that are glossed over by the dyed in the wool engineer mind set.....namely Danny's flat earthers...
Hi Danny, I am learning so much from you. I am curious why you don't use cones to seat your gear and speakers. Doesn't the vibration removal affect the sound for the better?
Well designed speaker cabinets don't vibrate much because they are stiff and heavy. The only vibrations you need to worry about are soundwave reflections. Research acoustic room treatment.
@@kmidst_mz5094 that's what I am doing, I am researching. There are some people in the community that vouch by removing any mechanical vibration from amps, crossovers, speaker isolation(hence my question).
@@andreimj Yeah I've seen that actually, amps on stands in order to angle them and such. Only high SPL bass could physically move anything around. The idea of acoustically isolating solid state gear doesn't make any sense. Like I said, speaker cabinets are designed to be acoustic isolation themselves because the speaker is a moving part. Otherwise, just the turntable needs isolation because of course vibrations mess with the needle's tracking.
We have all of our gear on that stuff. We use them with speakers some of the time. We move speakers in and out of the system so much that we often do not have them on some models.
If the Bass was audibly different between cables, couldn't someone set up a decent measurement mic and record a frequency response graph from the speakers and compare cable A to B? You could see the overlaid graphs and see if there was a difference in the freq curve between the two recordings. Is there any videos of someone doing this?
I doubt it exists, because no power cable can have such effect ... I have tried to look for some measurements supporting power cable influence, but only found some that prove that they have no effect.
Another manufacturer power cord sales pitch. If you add filtering, meaning active components to your power cable you could remove noise on your line, but if you look inside your components, this circuitry is already present. The gauge of the conductors will determine the amount of current that it will pass, more than 14 is a waist if the in wall cable and your breaker are both 15 amp rated. The insulation will determine the amount of voltage the cable can safely pass, fancy braid is for looks, and hides the actual basic internal wire/cable. You can add shielding, this will only prevent more noise from entering the cables signal, it will not filter what is on the line from the 40+ feet of non-shielded cable in the wall. Why don’t these manufactures supply test data to show the differences these power cables make on the AC signal (noise, voltage, and current), they do not because they know there is no difference. They seem to show all kinds of measurements for their crossover upgrades to show the improvements, why not their power cables?
If only we could turn the AC into DC, regulate and filter it and store it in a bank of capacitors, we wouldn’t have to pay $$$ for power cables.. Oh wait
I am an electrical engineer. I did extensive testing on power cables from alu to copper to silver using state of the art equipment. And I could not find any difference in measurements. Now the equipment is much, much more sensitive than the human ear. My conclusion is: if the equipment cannot measure any difference, nor the ear. In my opinion a regular $10 cable sounds the same as $1000 cable. It matter the state of your mind when you listen to music.
I don't need scientific measurements to tell me anything, the only measuring tool I need in audio are my ears. My ears tell me that free generic power cord that comes with your amp should be the first thing to into the trash after you unbox.
@@arize84 absolutely. I too am an Electrical Engineer and also a trained recording studio engineer and long time audoholic. What many people forget is that science is absolutely NOT truth, its simply our best understanding of what is observable. There is a tendency for people to dismiss observation and instead quote science to tell you what you can or cannot observe, as if science were truth, lol. There are a whole bunch of fools who will tell you that all correctly designed amplifiers operating in their design limits will sound the same. Its clearly not true, but it also clearly demonstrates that some of the things we hear when we analyse music play back are not currently measurable, and we don't understand the mechanic which gives rise to the difference. As long as the observation meets the scientific method (repeatable blind tests) then its an observable fact regardless of if we can measure a difference or not. Our 'electrical engineer ' clearly belongs in the group that would be stating that bumble bees cannot fly despite the fact he's getting buzzed by one xD When thigs cannot be measured, or we don't understand the mechanic, there is a lot of room for the snake oil salesman though, and the audio industry has more than its fair share of issues with these, so extreme caution is to be advised. The only reason to replace a cable is if you can hear a difference you like when you do. I'm a big fan of cleaning up the mains signals I plug my hi fi into, and as I've spent some time with this, I've found the cable itself not to make much of a difference with my unit and my filtered and corrected mains, but everyone's situation is different.
We should take into consideration the wires in the house and in the streets, too. I mean, what difference could it possibly make, if you change only 2 meters of the total length of kilometers all the way down to the nearest transformer or powerplant? The wires of the main grid of a normal house is built based on general purposes in mind, not audiophile concepts. You might have a noisy, far from perfect sinus waveform of the mains, but can the 2 meter long power cable eliminate this noise? Should the power supply circuit of an amplifier/deck/etc. get rid of these inperfections and provide a stable DC voltage for the audio circuitry? Does the lack of noise make a wide soundstage? Does the effect of the power cable will enrich the signal with something that is not present in the original source (e.g. more treble)? And what about the less than perfect cables and other conductive materials inside the amplifier/deck/tuner/etc.? So, there is a long and complex system of wires from the powerplant to all the way to the loudspeakers. What difference could it make if you change 2 meters out of 1 km? And if it works with 2 meters, can we do it by only 5 cm long professional power cable, too? It would be cheap enough.
But what if you add a socket adapter for either the US or UK plug? In case your country have a different type of socket. Would that have any effect on the performance of the cable?
Can you show us the difference in measurements? I understand that if you played us the audio we're listening on whatever speakers we have, but we would be able to at least note a difference in quality even though it's not a true representation of the sound. Without data or empirical evidence, everything you say is ultimately, untested and unscientific. Stories do not get the job done for me. I enjoy when you show before and after graphs for speaker reviews and what you did to fix them. Can nothing be done to show the difference between power cable A and B in a given setup?
The difference is real, it just takes an unbiased mind to have a listen. If you have already made up your mind that it won't work it will be hard for you to do a critical listening session to evaluate. You'll be saying it didn't do anything before you have even turned on the equipment. I was once skeptical that it would make a difference, how could it, it is only a power cable. But I did try it (other brands), and it did a lot of what Danny said it does.
@@DodgyBrothersEngineering Literally everything you said is backwards. The confirmation bias is you believing the cables make a difference, and then you magically hear it. But it's your brain lying to you.
@@Wizardofgosz if that was the case then my brain should have also lied to me about all the interconnects I have bought over the years. I can honestly say that I have not heard a "detectable" difference in any of them, and most have been expensive. To say I have would be wishful thinking, but power cables are a different story. There were noticeable differences from the stock power cables.
As a retired electronics tech I have to call you out on this one...If your ac power delivered to your equipment meets the voltage and current requirements the equipment requires to operate properly then there is no need for anything more and there isn't any possible way changing that power cable to some goofy expensive cable is going to make a nickels worth of difference. Using an uninteruptible power supply to keep constant voltage and to filter out spikes on the line is however a very good idea and should be used for ALL low level digital equipment. Match the size of your UPS to have 20% or so reserve capacity for the load it has to carry and you may see a lower noise floor by so doing, but I wouldn't do that with that expectation. What you will get for sure is longer equipment life and if the UPS fails to protect your equipment from lightning or some other power transient, there is a warranty in place that will replace the damaged equipment up to a pretty large number of dollars. Best insurance policy on the planet.
@@GRResearch Prove what you say is true. Show us the measurements. Simple no? If the difference is so clearly audible then it can be measured. Prove your assertions are true. I dare you. I am calling you out as a snake oil salesman. PROVE WHAT YOU CLAIM IS TRUE OR ITS NOTHING BUT BULLSHIT.
Let's talk next about little wooden trestles to get the speaker cables off the floor to combat floor decoupling wavelength phase band-pass electrostatic geo interference.
Carpets contain static from people walking on them. If the cable is located directly on the carpet then static can enter the cable and effect sound. Raising the cable from the floor helps prevent this.
I'm confused, I understand there can be noise coming from electric transmission lines. If an amplifier is able to filter its supplied power to a level that allows it to take the signal from the DAC and output it to the speakers with no distortion (and the cables to the speakers don't affect the signal) why should anything else matter? I'm not saying none of this matters or is impossible but I'm skeptical. I would think speaker wires acting as antennas would be a bigger problem. Surprised they aren't replaced with fiber optic cable that goes to an amp located inside the speaker, powering it directly. Also, I keep hearing burn in. What does that mean? Do the conductive properties change as electricity runs through them?
The fact is that anytime you add a filter of any kind there is an effect. Fiber optic cable only works for digital transmission. The burn is in about what is happening to the dielectric material of the cable.
I suppose to be thorough when touring the gear at shows would be to measure the noise on the actual outlet being used, based on your theory you should be able to best choose your wire that way.
I’m calling BS… If it were even remotely possible, the AC wiring and transformer inside the actual amplifier would make the difference. All of that is unshielded and within the chassis. As already said the quality of the power source and all the wiring getting to the outlet are much larger antennas.
Good boxes always have good power supplies built in include lots filtering. It's OK to have a dedicated power conditioning device for that purpose for all boxes you got, not $$$ snake oil power cables that is NOT controllable/adjustable.

He’s making videos with the intention of damaging Danny’s reputation, and he does it with a pompous attitude.That’s what I don’t like about Amir. And btw, The car going the speed of light or whatever isn’t a good comparison at all, and I’ve heard you use it multiple times. It just sounds silly. Let me ask you a serious question, and please answer it honestly. Do you just watch these vids and base your opinions on other people’s opinions, or have you actually tried different cables in your system? What about capacitors, resistors, tubes, etc.? Because I’ve heard it very clearly, I know for an absolute fact that different cables going from a turntable to a phono preamp can produce very different results based especially on capacitance, but that’s not the only factor. So, why would a cable going from your amp to your speakers not have different characteristics? They may be subtle differences, but it all adds up from your source to your speakers and it’s about fine tuning your system. I’m really not trying to be a dick either, Dave. Herb Reikert has a quote that I like that goes something like, we have the ability to hear what we can measure, but we can’t always measure everything we hear.
@@andydelle4509 Hi there Andy. I’m not saying Amir isn’t doing a service and doing it well. I watch his vids and agree with actually most of what he says, but he doesn’t seem to really truly listen. What I don’t like is his snarky nose in the air attitude, and this combative nature between TH-camrs talking badly about one another is not just healthy competition in some cases. Believe me, I very much respect you as an EE. In fact, I am now 45, but have a huge passion for electronics and was going to go to school for it, but my mother unfortunately got sick, and I had to change things around in my life. FWIW, when it comes to speaker cables, I use regular Canare 4S11 from Bluejeans cables. They’re well built, measure well, and sound good. For pwr cables, I just use good ol’ Belden, but was given a couple Pangea cables too. Ive also heard $1,000 cables which sounded awful. The difference between my pwr cables is negligible. Any difference I’ve heard in both my types of cables could well have been due to temperature or humidity effecting sound waves, etc. Whatever it was, it was so slight that I can’t justify or be bothered with expensive cables. Btw, my system is not crap at all, and it is plenty revealing. And yes, power quality is important, but a HiFi system obviously isn’t as important as what those UPS systems are providing power for. In the end, my real passion in life is music, and I was fortunate enough to have toured the world numerous times for playing my guitar, but that can burn you out after years of it, so now the world of HiFi is and has been my hobby. I appreciate good music, and I enjoy reproducing it as well as I can. Have a good week, Andy. Thanks for your comment. I enjoy conversations, not arguments. ✌️🎶🌝🔊👍
@@r423fplip You really have a LOT to learn. And those Revel's are a dull and lifeless sounding speaker. If that is your reference then you may not notice much if any change of anything.
Comparing water filtration to a power cable doesn’t work, they are two different things.
Water from the city pipes will not get cleaner by replacing your in home pipes. You incorrectly compared it to adding filters which would clean the water. Replacing the pipe won’t filter the water so the water will be the same.
Power from the wall will not “get better” by replacing the cable, it can only be “less bad” as the cable eats up electricity due to resistance, and using 12awg over 14awg would assist in that.
The only way to improve the power quality would be by running through power conditioner, which would be similar to a water filter. At that point you’re trying to “clean it” using actual tools and not just a cable. The only thing a cable can do is hurt the signal.
If you want to claim that it makes an IMPROVEMENT, and not a negative change to signal that you perceive as “better” eg: HF roll off, then prove us all wrong and runs the tests between cables. Gene at Audiobolics does, and he’s an electrical engineer on top of that. Sound is easily measurable, so if you want people to believe what you say, then prove it.
these guys would sell their mothers gold USB cables for 10.000$ telling them the computers will work better.
@@_UpVector_ so many idiots are all around the globe, so many many $ can be realised! ;)

I truly believe that a good cable can keep noise out and provide enough clean juice when needed to your amp. Beyond that NO! I have lots of expensive equipment and I do have some good $50 Power cables. Not wasting a penny more for nothing. I watched this guys video on testing kspeaker cable as an antenna for a stereo. What bunk. the only thing he proved is that braided cable has such good inductive rejection it makes lousy antena wire. I studied Electronic Engineering at USC, Avionics in the US NAVY, Worked at Bell Labs, was a sentior member of the SME...
Personally, I think this is a costly manufactured solution to a trivial or virtually non existent issue. I must however confess, that my local ‘bricks & mortar’ hifi dealer was having a stock clearance sale. I picked up a bargain. A 5 feet ‘high end’ audiophile mains cable reduced from 5 thousand pounds to 5 hundred pounds. I fitted it to my 1800 spin speed automatic washing machine. The results were phenomenal. Now, when the machine has a full 10KG load and reaches it’s maximum spin speed of 1800, the noise it produces is infinitely more pleasant. The highs are smooth and polished and have lost any hint of sibilance or graininess. The mids are clear, natural and full bodied and the lows are so well controlled the need for room treatment or DSP have been negated. The machine no longer goes for a walk around my utility room, though I credit this to the girth and binding qualities of the cable, not it’s electrical properties.
The downside. Because you know there is always compromises. My teenage daughter used to get a real thrill from sitting astride the machine when it reached maximum spin speed. That damned ‘high end’ audiophile cable has denied her that basic and simple pleasure.
Enjoy the music.

When you do, be sure to introduce them through a gate or window for a few hours first. let them get used to each other's presence before allowing them to make direct contact, otherwise your investments will be wasted.

Hi Danny, “flat earther” here who wants to like your work on crossover designs and speaker upgrades, but I have also handled power supplies for computing measuring in the kilowatts and theater lighting arrays and sound systems where deploying arrays that pulled nearly 100 killowatts wasn’t out of the ordinary. I’ve used actual power conditioning equipment. I’ve also built countless power cables with numerous terminations for equipment that can pull up to 10KW at full power. I absolutely cannot condone anyone buying a $250 power cord. My 20 year old self would laugh, and my present-day near-40 year old self just feels sad. Here’s why:
Consumer and prosumer audio equipment have switching designs to get from the unusable-for-anything-but-wall-sockets alternating current to direct current for use with anything inside an amp, DAC, preamp, etc. To go from AC to DC, electric power goes through a transformer, a rectifier, and several filtering and conditioning stages to smooth out variation and ripple, before it even touches anything else. (Never mind the fact that some integrated circuits have specific tolerances where they simply don’t work well, or just fail outright, if they run out of spec, so clean power delivery from the output stage of the power supply is a must.) Much like speaker wire, so long as the power cable is using the appropriate gauge for its length as to not melt and start a fire, it’s fine.
I think, outside of the audiophile community, you would be (rightfully) laughed at if you said you purchased a $250 power cable… I can buy a whole 92%+ efficient 1KW power supply for that money, and it would come with a pennies-on-the-dollar, 2 meter long, 16-gauge C13 cable, and it work exactly as expected. A better power cable wouldn’t make it work any more efficiently or have more stable 12V or 5V output. Wouldn’t have to even buy one of those weirdo power conditioners either. (Again, I have dealt with real power conditioners for actual high load situations. They are not small and they are not quiet, and they belong nowhere near audiophile equipment.)
I can only agree with you on this one! Although I'll have to add an asterisk to the whole power supply and filtering thing, that being switching noise and the resulting EMF can introduce noise to high impedance signals between your components. However this is mainly an issue with really cheap gear, the kind with improper back EMF protection at it's power input, cheap high ESR caps, needlessly high input impedances, or any stupid but cost saving design measures. Cheap switching AC/DC power supplies and their DC(+ f>45kHz AC) power cables are notorious for this as well. You wouldn't ever use this professionally though, as you wouldn't plug in a power-LAN Adapter next to your mixing desk.
I would say - the converter can only do so much, so if AC is balanced in, the DC converted better, like a water filter, the more pollution in the more pollution out after it has been cleaned

Bingo, I love when actual experts weigh in on this bs snake oil.
Which chart do you use to measure electrical noise levels?

He counts on his uncanny Spock ears for power cables.
Oh dear. Yes cables CAN make a difference - if there is insufficient gauge or poor connectors. But a $5.00 cable will have the necessary gauge and it is trivial to make a good connection. Spend your money on speakers. The reason this is so sad is that Danny is right up there when it comes to speakers - but now he descends to snake oil.
Agreed. I just can't believe that he has become so O.C.D about "F" ing cables. As you say, smart people know the differences and what types of cables are required for different applications, but honestly, in my 62 years I have never heard anyone bang on so much about this topic.

Let's just enjoy the music shall we and leave the indoctrinated to believe that their deep pockets justified their supposedly better listening experience.
Any good power supply is supposed to provide isolation between the component and the mains. There is a case to be had for heavy gauge power cable for anything that draws a lot of current. But for your average 15-30W component, either the power supply isolates it from the mains, or it should be replaced.
And quite frankly, you'll get more noise from the RF produced by a modern power supply located close to the signal path than you'll get from the mains. There's a good reason why computer PSUs are locked inside a fairly sturdy faraday cage, and audio component power supplies should be too (imo).
I know a guy who hooked up his component stereo system to a UPS with isolation. What is fed into his system is a pure sine wave from batteries with perfect isolation from the mains. You can't get more "conditioned" than that, and there's no audible difference whatsoever. The UPS is a $400 component meant to protect his other $20,000 in components.
Again, there is an argument to be had for heavy gauge power cable going to the amp (at least equal to the house wiring). But if the power supply of a 15-30W component cannot filter out noise from the mains, then it's a POS you should never have bought.
@@grahamserle7930 well he is so effective with his previous work because he has been able to show how he made sens of it all.

They are not proving anything. They are taking measurements and then theorizing if there will or will not be ab audible difference. That's not scientific evidence. That's just a belief.
And we do blind listening comparisons over here all the time. That's how we confirm results. We listen.
Hi, interesting video..do you have any measurements or just products links?
i think double blind listening tests are the gold standard for this sort of thing, as knowing what's hooked up can influence how you feel about the sound. i'm sure cabling and the power source can make a difference, but for me at least there are just hard limits on the lengths i will go. tube connectors and good speaker cables seem reasonable, but i don't know about power cables. you would need a good power strip too
Make two identical setups and identical rooms. Double blind test. Pick what room gets a good cable at random. Repeat few times.
Going through all the effort of a double blind test just to learn your brain works like every other human brain and you do in fact not have an audiophile super power... Why would you want to do THAT?
@@Jako1987 that would never work. Can't have both setups identical. It's much simpler to have 1 room and 1 system and just have one guy switch the power cable, and see if the listeners can tell A from B. Doesn't even have to be double blind.
@@lmoelleb Yep... Sad thing about this video, makes you doubt every other video/claim! I mean sure, it's kinda fun to listen to, almost like you'd do for other supernatural stories; ghosts, living in a simulation, etc., but yeah... Kinda hurts the credibility. Really needs a BT or DBT to confirm, without it.... Ouch... Cred - 100
Anyone spouting off the words "double blind testing" doesn't know how A/B comparisons work or how they are conducted.
Why have I never seen any of these cables in Recording Studios? Surely the same argument must apply.
Because it's nothing but bullshit. Worked in and around studios for 30 years. Abbey Road, Air etc. Places with 200k and up of custom speakers and the same on amplifiers in room designed by the best in business costing literal millions of dollars to create. ALL wired with the same Van Damme mutlicore and all connected with the power cables that came in the boxes of the kit. Studios can have 10's of miles of cables in them.
No one pays ANY attention to this nonsense outside of audiofail worlds.
Also why does he not measure these cables? He measures speakers to show the issues. Why not cables as well? Simple answer, measuring would show how full of shit he is on this topic.

If you're filtering out HF/VHF noise out of AC mains, how is "too much filtering/conditioning" a thing? Unless the filter designers are chopping the sine wave at 50/60hz. I mean, isn't that just a bad conditioner design? Show me AC mains straight to a scope, and then show the scope on the end of the fancy cable/conditioner/regenerator. THAT should be your selling point.
There's more to it than just looking at a sine wave, a high res FFT also tells a lot.
@Douglas Blake mate you completly missed his point. he rightly asks what the problem could be about filtering too much. Video says it makes the sound dull, well can you explain why?? that would be a selling point!
@Douglas Blake I've made power cables with caps across the lines too. It's not a fix all, but it is a nice little tweak.
How can filtering go too far? Simple...output impedance.
@Douglas Blake A simple cap can remove some RF noise. It creates a first order style filter. So it just removes some of it. And on the interconnects it would easily become a high pass filter. So no, it doesn't work on interconnects.
The old cable controversy at it once again. Let me ask you a question. If the power cable makes such a difference then you should be able to measure it, right? Here's the problem, you cannot as there are no differences between snake oil power cables vs the ones that came with your components. Furthermore, if, and that's a HUGE if, there was a difference, even a small one, don't you think that major players such as McIntosh, Musical Fidelity, Bryston, Rega, and Naim just to name a few, would offer a choice in power cables? They do not! Why? Because they know full well that it does not make a difference. Also, if you call any of those manufacturers, they will all tell you to stick with what the equipment came with. There's no need to buy cables that cost an arm and a leg.
I can just imagine going to McIntosh or Bryston and tell them that their $10, 000 amps and preamps would sound so much better with a better choice of power cable. You guys manufacture and test your equipment up to wazoo but clearly, you need to fire the one suggesting that a $20.00 power cable is enough...right? That with a $250.00 dollar cable, your equipment would be so much better? I wonder what their answer would be?
By the way, let's not forget the blind test. Funny how not one of the so called pro's selling those cables, refuses to participate in blind tests. I've challenged someone who makes speaker reviews online and in magazines, to blind test 3 speakers ranging from $4000 up to $10,000 and compare the result with previous reviews of his. Guess what? He refused! It's easy to sit down and make reviews based on high quality and expensive equipment when you are aware of the brands but not so much when you are in the dark.
By the way, all REL manual says 'Only use the power cord supplied'.
Naim does offer a choice in power cords!
@@cameronkrause4712, right! I remember now how they sold out to please those who believe it makes a difference. Quite amusing when I think about it. Even funnier when people pay big bucks for something that makes no difference in sound.

I absolutely agree with you to a point. (I tend to think this is snake oil, but I do have an open mind despite it going against all known measurements.) Danny claims that this must be "listened to" instead of measured. Maybe, he has a point - maybe we don't have things to measure it? But, a simple blind listening test, could confirm he has something, or not... And if there is something, the test can be made more and more perfect with scientific, peer reviewed ideas on how to improve the testing. But, there has been NOTHING so far! Is that not the very way that flat earthers have "proven" their theory?"
This, is insulting to science. I'm not saying he is wrong. If the effect and differences are as great as he claims, it should easily be able to be tested, verified, repeated, etc. While the first "evidence" may not be perfect (i.e. not a double blind, controlled ABX test...) I'd just like to see 4 out of 5 people state which cable is which since it's "so easily audible."
Danny does a lot of things great - I have learned a lot from him for certain things - but, he can't go on saying that everyone else is wrong, without presenting actual evidence for the claims that he makes. It can't be measured, only heard? Fine! Setup a decent listening test and present evidence! Until then, he's the one on the side of the flat earthers denying all other measurements.
Rega have a special cable in the high end range.
@@FEGTTTSDH Rega has a jazzed-up cable for the Osiris integrated amp. It's not an option. In their own words: "A Rega designed fully shielded, high quality, high current capacity mains lead is included." Apart from being fully shielded and slightly higher current, how does that make a difference with other cords? Rega does not state a single word about a sound improvement which is normal as if they did, then they would need to offer such a power cable as an option to other amps, right? Jazzing up a cable for a $10,000 integrated amp is more for show than anything else.
I am oriented to science and facts. I thought there is no way a short power cable can make a difference. I also read many articles expounding the virtues of power conditioners.
I experimented with DIY power conditioners and found exactly what Danny describes. A little can help, and too much can kill the system. Isolation transformers slightly reduced sound quality. Inductors, even a small amount could kill the sound stage and make the sound dull and lifeless.
Power cables are where I was shocked. I found a substantial difference in sound. I make my own, and they are a solid improvement in bass, sound stage etc. I used some DIY recipes from VH Audio cables with 10gauge wire. Sounds terrific. I put minor amounts of filtering in the distribution box using caps and also built a DC block circuit to avoid transformers from buzzing and saturating. This was all I need. There is only a couple feet between the conditioner/distribution box and the electronics. I also built an 8 foot cord to go from the wall to the distribution box. I also put a ferret clamp on the safety ground at each consumer. An inductor or a ferret clamp is not good on the power wires. I cannot explain any of this other than the notion of an appropriate amount of filtering. It could also be that the caps act as a volt/var circuit. I live in a large city and there is a ton of noise in local distribution including RF over power. My house is full of LED lights, dimmers and switch mode power supplies. There are several computers plugged in and powered at any time. Every house on the street has the same. We all have a plethora of radio antennas for wifi, cellular, garage doors and home automation. Somehow these power tweaks that cost me nothing helps my system work well.
What are the factual scientific differences between what the cable does and what a conditioner does? (With reference links, please.)
@@doctorfuzzzdirtbox With all due respect, feel free to do your own research. I have reported my circumstances and subjective opinion. Do with it what you wish.
IMHO, there has been very little scientific study of the subject so there will be very little to be found. No one needs these things. An amp or a DAC will function safely if fed power by any UL approved power cord. But as I report, I and many others have been surprised that different power cords do in fact make a substantial difference in the sound in well resolved systems where low level detail is appreciated.
@@user-od9iz9cv1w most of the people commenting on here are just parroting what others have said without even trying a different power cord. They keep making the same stupid comment that is the resistance is the same then it must sound the same. Well half of them are probably relying on someone else's measurements to make this statement, or don't have high enough quality testing gear to see a difference. Because if your equipment is sensitive enough no two cables should ever be the same.
Using that same theory if an open baffle speaker and a boxed speaker measured exactly the same the should sound identical. Yet they sound nothing alike. Why is that? Because half the time people are measuring the wrong thing. How does resistance of a wire tell you how well that cable is insulated if you have it near some noisy equipment?
@user-od9iz9cv1w With due respect, I've done my own research extensively. I now want to know what I've missed, if you'd be kind enough to share.
@DodgyBrothersEngineering As an audio engineer of 20+ years, I just want to know how I can find these results for myself because a speaker, with varying design cannot measure the same in all metrics. So neither can a power cable. As an engineer, I don't believe in my own ears. Psychoacoustic fundamentals can prove that our brains can very easily lie to us. Especially when cognitive bias is involved. So we need hard data to see through the mist.
Sorry, but if the bass response of your power amplifier changes because of a different power cable, you should have a serious conversation with the manufacturer of that power amplifier. A quality amplifier must have quality internal voltage circuitry that is independent of noise, RF reception and whatever the power line does. Period. If equipment sells as "high-end" but you can hear the neighbors washing machine switch on or a Russian opera station via the power supply, the equipment is not high-end. Somebody screwed up in the design.
Audio equipment should not be designed to only operate correctly in a military-grade Faraday cage listening room with filtered power supply.
Sorry, but current delivery is and can be effected by the power cables.
@@MrsZambezi Of coarse it can. You have no idea what you are talking about.

@@GRResearch My oven is able to use 2900 Watts for as long as a recipe takes. The power cord that came with the oven can take that, does not become warm and probably costs about 10 or 15 bucks. Any power cord that can continuously handle a pretty energy-hungry household appliance that uses, say, the peak power of your amp divided by its efficiency, is good enough and does not have to be expensive. The power circuitry should take care of smoothing and buffering. If you hear the difference between two cables that meet the above criteria: that's a flaw in the amp concerning design, part quality or age (capacitors come to mind). If your amp comes with a cable that does not meet the above criteria: buy another brand amp. Apparently they don't take things seriously. Or use the cord of your oven ;-)
@@GRResearch
Research does not always means science or relevant to the application.First they talk about a "representative equipment sample" but do not specify what "segment" of the market it should represent, for example the "audiophile" market segment. Second, the actual used equipment is not mentioned, so there is no way to verify if the sample is indeed representative. Third, they mention "a variety of product" inside the equipment sample, but there is no method mentioned how the result are aggregated to produce the graphics shown. The previous leads to an experiment that is unclear about its scope, its methods and about its sample-set (the equipment). This means the experiment cannot be reproduced and the results cannot be verified. The result is that the experiment cannot qualify as "scientific".
However, even if the experiment was scientific, the maximum scope of the result is _the sample of equipment used._ As long as we don't know that sample, we cannot draw conclusions.
And even if we would know the exact equipment, we have to make the assumption that the drop in voltage/current has a noticeable effect on the desired behaviour of the equipment, for example the accuracy of audio signal reproduction. _For the sake of argument_ I will assume that this deviation from desired behaviour is a fact, event though it is highly dependent on the circuitry used.
Now let's assume that the article relates to the audiophile market segment. Because we have assumed that the measured behaviour has a noticeable effect on the desired behaviour of the equipment - in this case audio reproduction accuracy - audiophile equipment MUST have a good power supply.
What is a good power supply?
A good power supply perfectly separates the characteristics from your wall-socket and the characteristics that the internal circuitry of you audiovisual sees. Whatever power characteristics come in, as long as it is "enough", the internal circuitry should see an almost perfect voltage-source: a voltage-source delivers a constant voltage that is independent of the drawn current. In yet other words: disturbances that enter the power supply should be invisible at the other end.
Naturally, there are theoretical limits. If the average amount of power that the power supply can get is smaller than the average power it must supply, things break. But the power supply should definitely hoard enough energy to cope with (short) bursts of current demand at a constant voltage. The used 50 microseconds in the experiment should be peanuts and should _definitely_ not be passed on to the power cord directly!
Outcomes
The first outcome from the experiment is that the used power supply of the graphics _is not a good power supply_ at all. It does not buffer enough energy to support bursts and quickly becomes largely dependent on the input power. This will make the circuitry that it feeds see disturbances like power limitations, zero-crossings (wall-sockets are AC and when voltage difference is zero you cannot draw current) and potentially for other fluctuations that are caused by other equipment on the line or the power company. Not good.
The second outcome is that this equipment should never qualify as audiophile, unless it is pampered with laboratory-grade power cords and sanitized power (which does not remove some of the mentioned problems). A consumer should not have to depend on that! And if the power supply is that bad, that doesn't bode well for other design decisions made in the equipment.
The third outcome is that the manufacturer of the equipment gave a bad power cord. The reason is that if the cable makes a difference, it is very under-dimensioned, possibly leading to even more degradation caused by getting warm or even causing a fire hazard. It can also be that this experiment used the same "representable" cable for all measurements, but there is no way to know. By the way, if your amplifier needs a power cable that can deliver more power than your wall-socket is rated at, you can also get in trouble with fast fuses. Your equipment _should not_ depend on that. See the story about power supplies. A cable that can supply an oven or washing machine without a noticeable increase in temperature, is generally fine.
Conclusion
If you do not know the quality of your equipment, you can borrow a cable from a heavy household appliance like an oven or a washing machine to see if it helps. If it helps, you should not consider your audio equipment as "audiophile" as its power supply can't make that happen. Because certain problems that are inherent to your power supply cannot be fixed with a cable unless you pamper your equipment with laboratory-grade power cleaning and cords, but you shouldn't have depend on that as a consumer. Naturally, you can then use an expensive cable if that makes you happy.
Good audiophile equipment comes with a good power supply and a good enough cable. If swapping the cable for a better one helps, consider asking your money back for both the cable _and_ the equipment.
@@GRResearch The copper distribution wire going from your electrical panel to the outlet you plug your stereo into is 14/2 CU where I am from and as well in the US, typically protected with a 15Amp breaker.

In the nighttime you are still running the inverter but not charging. Don't you rather think it is the charger imposing its noise on the supply? Best regards, Rob

I so of agree, but how can you over filter it? If you manage to remove all ‘interference’ from the cable you have done just that. It implies some noise is beneficial.
How does the "sound stage open up" when stereophonic spatial differences require stereo channel level or time differences? How does the power cord produce stereo channel level or time differences in identical and independent audio signal paths?

If these cables do everything said of them, why don't the equipment manufactures integrate them into the equipment and do away with the plug/socket which is apparently another item that introduces distortion.
should I modify my old devices with attached cords to take modular power cord?
We should take into consideration the wires in the house and in the streets, too. I mean, what difference could possibly make, if you change only 2 meters of the total length of kilometers all the way down to the nearest transformer or powerplant? The wires of the main grid of a normal house is built based on general purposes in mind, not audiophile concepts. You might have a noisy, far from perfect sinus waveform of the mains, but can the 2 meter long power cable eliminate this noise? Should the power supply circuit of an amplifier/deck/etc. get rid of these inperfections and provide a stable DC voltage for the audio circuitry? Does the lack of noise make a wide soundstage? Does the effect of the power cable will enrich the signal with something that is not present in the original source (e.g. more treble)? And what about the less than perfect cables and other conductive materials inside the amplifier/deck/tuner/etc.? So, there is a long and complex system of wires from the powerplant to all the way to the loudspeakers. What difference could it make if you change 2 meters out of 1 km? And if it works with 2 meters, can we do it by only 5 cm long professional power cable, too? It would be cheap enough.

As a polymer technologist who did his PhD on Polyethylene, I'm interested to know what kind of changes can occur with Polyethylene at room temperature in a so called burn in phase that would affect its electrical insulation properties. Polyethylene is a semi crystalline polymer and crystallises as it cools from the molten state at between 120 - 135 deg C depending on its polymer structure. the amorphous phase between the crystallites is above its glass transition point and is in the rubbery state and will experience some relaxation of the built in stresses within the material caused by its rapid cooling from the melt state 9during the wire coating extrusion process. but whether a bit of molecular relaxation in a non polar polymer insulator would or could affect sound, remains to be seen, or heard... as a LINN Owner, arent we used to being flat earthers?

I think you havn't watched his videos at all. He do combine resonance graphs with listening. That's what he is doing for a living among other things.

@@theklipschcave5593 The trouble with Danny lately is that he uses strictly measurements - actual science - for "improving" speakers without regard to how they sound (many sound great to begin with), sells improvement kits whose results you may actually hate, then recommends cables (he also sells) whose effects he can't measure, but assures you that they make a difference in sound.
If you are not happy with your speaker, get a better one. Don't expect a difference if you wave a magic wand over yours with nebulous cable claims. Then again, ignorance is surely bliss.

I like your speaker upgrade videos because you provide graphs and data showing how the frequency response etc have changed. If these power cables make the sort of audible difference you describe then where are the measurements that show the sound out the speakers has changed when you swap between standard and premium cables?
Don't hold your breath waiting for the data. It would be easy to do the measurement since he's done them before. It's not hard to guess why it wasn't done or why it was done but not presented here.
Yes, he has said in at least one video on YT he doesn’t need to listen to speakers to improve them. He just uses the FR graphs to show his improvements. But for cables it’s the opposite (?) You have to hear them, not measure, apparently. 🤷🏻♂️

Our in house internal wire is four 9's pure Copper in polyethylene. So pretty good stuff...
One factor that is ALWAYS overlooked is - how good are your ears? By the time most folks can afford a top end system their ears will have a HF roll - off that appears to make system sound dull, one ear may have been slightly more affected than the other which can blur the sound stage, and due to the wear and tear of the ears mechanics the dynamic range suffers, ie. a bit deaf so the quiet parts are too quiet so you turn it up, then the loud parts are too loud 'cos the ear cannot handle the sound pressure dynamics and it sounds distorted. You could spend a million bucks on the technically perfect system and it will sound poor if you don't look after your ears. Perhaps instead of spending on power cords get your ears tested!
And that is a fair question... What I used to say to my mother who had a bone defect in both of her ears, and had both of the bones in her ears replaced with a silver wire was... The worse your hearing, the clearer it needs to be. In later life mum got hearing aids to try and help her hear better, but she didn't really need them. The operation reduced her hearing to a very narrow band of frequencies. She could hear between 3000 and 5000hz OK, but outside of that she struggled. So it was often harder for her to hear what I was saying than it was for one of my sisters who talk in a higher frequency range (and volume they all yell when they talk). But if I took mum out of the echoing kitchen into a bedroom where there is carpet, and spoke to her standing right in front of her, she could hear me perfectly without needing to raise my voice. Nothing changed except the clarity in which she could hear me.
I've said this for years, everyone has different hearing and loss at different frequencies.
Getting your ears tested won't affect what you can/cannot hear. Once your hearing deteriorates, there's no going back. Hearing protection should be aggressively enforced when people are young. It's impossible and impractical.
Orchestra musicians are subject to very loud sounds, but they're not wearing hearing protection. Many members in groups with amplifiers use them, and many wear in ear monitors to be able to hear the whole band. Audience members should be wearing ear protection. Loud concerts sound better with ear plugs.
Is your 24 Strand DIY Audiophile Speaker Cable same as the Kimber Kable 12TC ?
Simular, but we add a few tweaks that take it a couple of steps further.
@@dannyrichie9743 Don't tell me your cables are better than Kimber by making little tweaks here and there. Stop lying.
@@ceddy1031 I never lie, and those tweaks are not subtle.
You've got the gear. Please do a before and after test of the noticeable difference. Lets see some charts/graphs. Thank you.
What makes you think the differences are going to show up in an amplitude chart?
@@dannyrichie9743 Its simple, if the power cable makes a discernible difference in the sound (which is his whole argument) - then show before and after charts.
Are you implying that we will hear a difference but it won't show in the charts?
@@aportilla007 There is a LOT that we can hear that is really tough to measure.
@@dannyrichie9743 So you are saying that the sound will change but it is not measurable. Can you provide an example?
We are talking about changing just the power cable. At the wall, inside the house, the electricity comes from a 14 gauge wire.
We aren't talking about power conditioners or giant caps or batteries being added, or specialty taps being run from the panel. We are talking about a common house 14 gauge wire that feeds the power cable.
The whole argument is that changing the power cable will change the sound. But GR-Research has provided no proof, neither have you. Just heresay, "because I say so".
Now, if you were to tell me that there was a 120 amp run from the panel, 10 gauge, and then a power conditioner - that would power the components more linearly, because the power is on constant tap and there is a lot of it.
In the valve world, some people actually like under-powering their amps to get the brown sound. This happens as well with keyboards and guitar pedals. And, there is absolutely a measurable sound change.
But, we are talking about solid state that is designed to work with that shitty common house outlet. If the output difference is not measurable, then its psychological. Please provide examples.
@@aportilla007 No problem. The geometry of the cable changes the capacitance and inductance of the cable so that it acts as a filter for higher frequency ranges. So it is more resistive to the upper ranges blocking a level of noise out. And we can easily measure changes in capacitance and inductance. The audible effect is quite apparent. Measuring the audible effect is not at all easy. It is a lot tougher to measure what is not there opposed to what is there.
A lot of people commenting on Danny but very few who actually take up the invitation to put his assertion to the test. For me, I listen to the fellow who do audio experiments on a regular basis
Because there are plenty of videos on here that already prove it's wrong goofy
Have u scoped it on a spectrum analyzer, and network analyzer? Curious to know line noise and mains/inverter impedance in each case. Maybe attribute to maximum power transfer from mains to amp, and cleanliness.
May I inquire: Could an Wireworld Electra 7 into a Audioquest Niagara 1200 be too much conditioning?
Hell no!
The thing to remember is the diminishing rate of return. MOST people will reap the most NOTICEABLE benefit with a good Filter/Protection strip and "shielded hospital grade" power cords. That means you do not need a $1000 "audiophile" power conditioner, you will be just fine with a $100 Furman or Triplite. As far as the AC cable, you would have to be in a VERY electrically noisy room (like a trade show or computer room) to really need it, but if you need it A shielded Hospital grade power cable (that has a grounded outer shield is all you need). So again... a $10 hospital grade AC cable will sound the same as some snake skin $200 AC cable.
What does 'hospital grade' change over a regular power cable? Maybe it's a lesser evil than full blown snakeoil cables, but they certainly won't sound any different than any $2 computer power cable...
@@literalghost929 hospital grade is a thicker conductor and an EXTRA shield that is intended to reduce emi rfi signals that may be flowing in electricity. They use them to make sure those signals do NOT interfere with medical machines and meters.
@@franciscoortiz6980 That won't change anything. Check out Audio Science Review "GR Research B24 AC Cable Review: Does it Make an Audible Difference?", he compares a cheapo cable and there's absolutely no difference...
And it's perfectly logical, the electricity from the outlet/cable passes through a power supply: Transformer, caps, diodes, etc., there's no way any 'signal'/noise goes through the PS.
Btw, HP grade cords typically aren't shielded.
@@literalghost929 dude... i am not going to argue with you. You clearly are the "free cables that come in the box are great" opinion. I am NOT a $500 cable guy... i am somewhere in the middle... the way cheaper middle.
@@franciscoortiz6980 There's no middle... Either you get the answer right or you don't. It's like saying, look, I'm not going to buy 500$ worth of healing crystals, but I'm just going to buy these magic healing crystals that cost 15$, so I'm not with those who believe in magic, I'm in the middle.

Try Oneac line conditioner. We used them when we sold POS equipment. They are hooked up to every machine in a hospital. Check it out. Great and not expensive.
@Car Guy daddyo Oneac's are great. Industrial every machine in a hospital has them.
I run 2 300B mono power amp and I use 2 fat silver plated fully insulated power cables to feed them. And a 700watt ups with pure sine wave to feed them it really makes a huge difference. Your right Danny. Keep up the great work
Nope, it’s doesn’t. Placebo
@@DanielC__ exactly. What they charge for these cables is truly obnoxious. It shows just how gullible "audiophiles" are. (These are the same people who will pay hundreds on cable elevators).
It's amazing - the power of suggestion is a mighty powerful thing. It's psychosomatic.
I've done the listening tests on expensive systems and midfi. I could not tell the difference with the normal factory power cable and the ridiculously over priced crap.
@@bunk-bn9eo Agreed. Early in my career I spent 6 yrs selling Hi-Fi gear in a few shops. There is plenty of good sounding gear but it’s so subjective. Having literally done or been a part of thousands of A vs B vs C equipment demos there is one over riding result: people buy with their eyes. The people that identified themselves as “ audiophiles” were the most entertaining with blind tests. We could A B gear that was identical multiple times, they couldn’t tell. We hid standard grade speaker wire, interconnects in fake larger casings…the big cables always sounded better to them. We had special large speaker cabinets that we could insert much smaller speakers inside. People either loved the awesome bass response from the “big” speaker or others had a bias towards bass and thought big speakers were to boomy. Yet, we could play identical small speaker beside fake speaker and it would sound more refined not boomy. If we showed them a fake inflated price tag on gear, they would pick the “expensive” gear most times. We did fully disclose these testing “tricks” to customers to show them sound is subjective. If you like it, get it.
I'm with you Phillip! 🇺🇦🇺🇸👊
What does the wire in your wall look like? There is your answer
I bought a $5000 BS filter and it did an amazing job of improving my entire system.
Can I interest you in some audiophile paint? “high Frequency White” is particularly useful in countering the dreaded “Dark Sound” caused by too much filtering. Only $999 a can. Don’t knock it if you have not tried it.
Do you offer a discount for bulk buying? Do you find that Matt or gloss is more effective? How many coats do you have to apply, before the ubiquitous laws of diminishing returns rear their ugly bonce? If I were to put a couple of coats on the inside panels of my speaker cabinets, would this make them more inert and work out far less expensive than a couple of sheets of Danny’s ‘no res’?👍🍻

You should look into Shun Mooks products. You'll die laughing. He creates a wazoo pendulum made of apingo ebony wood dipped in the swamps of Africa that spins and changes the energy in your hi-fi gear or so he says to sound better.

@@dannyrichie9743 You deserve all the hate coming your way...I hope you go our of business
Danny what gives you a better performance your 1800 rca connects or a 10 dollar XLR cable?
You can get much better sound from using a good RCA cable that filters out noise. The problem with XLR's is they they won't filter out noise already on the line. They only filter out the noise they pick up as being an antenna. So they pass whatever noise was there to begin with without adding more.
Danny, You should run the cables through ETL or UL to keep yourself and customers out of trouble with non-paying insurance and potential lawsuits.
Heads up! There are thousands of electrical products on the market without third party testing approval.
@@scottmichaels1764 Absolutely, and many that generate noise in your home electrical system.
@@jameswarren1831 more worried about fire. Or other problems.
If my power is run from fuse box to wall outlet and it's not sheilded just 3 conductor solid 14gauge romex, How do I get greater performance from the outlet to the equipment with this massive cable? Maybe if all the cable had similar build and gauge but you can't correct garbage in garbage out with some magic in between.
like any other solution to any problem, first the problem must be understood and identified. then one must figure out how to effect correction to the problem.
I have yet to hear anybody identify what the problem is with the factory supplied wire to the wall, and what can be done to correct it. I hear , "OEM wire bad, expensive wire better, with never a solid reason or an identifiable defect about why change is needed . Unless you like to spend money just because you can.
The correction the wire sellers speak of is to spend money, cross your fingers and listen, maybe you will hear an improvement, they can't say, disregarding the known fallibility of human hearing , while simultaneously failing to identify the problematic mechanical system in the wire that needs to be corrected in the first place , with the more costly , fancier wire.
I change the power cable on my Delta Unisaw Table saw today , It cuts faster, smoother , quieter, Less vibration on the cast-iron top. I would like to do a double blind test but I am scared , I’ll cut my fingers off 🤔
I changed it on my kettle. I could swear that’s it comes to the boil far more quickly and is slightly definitely maybe quieter and the water tastes cleaner. It probably cures COVID-19 too.
Not sure it can cure covid, only make it sound better 😇
Me too, haven’t sharpened my blades in 10 yrs. Amazing what them cables can do.
I have a friend that works at the CERN. He was able to put some of my old cheap power cables in the most powerful particle accelerator in the world on an off shift. You would not be able to believe the difference it made to the sound! It now funnels muons, pions and quarks and changed the subatomic structure of the wire itself. Anyone want to buy it for $10K?
If I buy your cable it will lower noise that I can measure with an entach power line meter?
Is that what you need to know? Or does it need to make an audible improvement?
Great information about how power conditioning can affect an audio system. It's definitely necessary.
I have 2 test cases:
1) What if the amplifier/CD player etc. has an inbuilt power cable? Meaning it's soldered onto the board and goes directly to the power transformer?
2) What if you buy some audio gear and it comes with a removable power cable? is it junk? do you throw it away?! Might this also be necessary for other electronics?
Let us assume you have a power conditioner. It's going to protect all of your audio gear and feed it clean power. IMO, hospital-grade power cables are where it's at. They are made to NEMA 5 - 15P specifications; which would also ensure ideal performance with sensitive medical equipment. If we have high-end audio gear that may be sensitive to drops or peaks in power, these cables should work fine.
That's been my experience...
No, it's snake oil.
@@ericgardner5548 i have to disagree. As a matter fact, audio amplifiers with soldered (hardwired) power cables won't benefit from a new power cable. But any other component that uses an external power supply will.
NEMA 5-15P is a (P)lug end that goes into a 5-15Recepticle at 15 Amps peak power. Has nothing to do with anything else.
a voltage stabilizer is the only thing about this that is not snake oil. this is the most ridiculous debate ever. unless you condition or PHYSICALLY ALTER THE POWER nothing changes, assuming the wires are equal to or greater conductance than the outlet itself, or unless you are replacing a bad cable oxidized or damaged (internally) with a good one. i have blind tested people with pin drop hearing and you can really mess with them and make them think the standard copper cable is the upgraded one. simply its a placebo and i am SHOCKED that this video was made by a man i thought was smarter than this. but then again he does use the same exact capacitor series when he upgrades everyone speaker, so there is bias involved too. i have done so so much extensive testing on different capacitors with different tweeters and you just can not use the same cap on every tweeter made to get the best result. hes nice to listen to and has lots of great input, but in the end he has convinced himself that one size fits all, and now he joined the cable placebo. again, this is not talking about using crap cables and upgrading them to ones that match the output and length, this is just silly silly placebo effect. its simple: its a good wire or its not, the end. anything past that is about the equipment itself and yes voltage stabilization so the circuits do not dip up and down in power in/out
@DJ FireStorm ever heard of a power transformer inside of an audio amplifier? It takes care of voltage. A power conditioner simply filters electricity that is compromised by noise. Power cables can make a difference - specifically, with Class A amplifiers that are inefficient by design and require power on demand to perform well. Just use 2 awg thicker than the standard cord, and you should be fine. I am not suggesting power cables that cost many hundreds or thousands of dollars.

No, you missed the point. The guys claiming that they are using science and engineering principles are using them to form a theory. That's not science. To answer a question about audibility requires listening to get the answer.
@@dannyrichie9743 using science and engineering principles to form a theory being compared to flat earth theory is unironic. Got it.
@@danryan4272 Yep, that's all it is. And the irony is intentional.
i built a cable using some lower priced connectors and supra cable (LORAD 3X2.5 BLUE B50) and plugged it in to my marantz 8012. I have a full atmos setup.... what I noticed asap was the noise floor dropped by a ton... honestly the noise floor getting quieter, let the audio play 'more' -> i could add adjectives but sharing what happened effectively without explaining how I heard more from the music is the best way to say there is a difference. your cables in a system can act as antennas as Dany said, and that supra cable I built is cheap proof of that. Probably those oscilator people could come over to my place and make some measurements :-)
How do I figure out which model of your power cords is better for me?
Don’t buy em, you’re getting sucked in to moon bat thinking
Can you please do a video on power cable length ....I've always been told that 5ft was optimal ...but that shorter or longer will indeed sound different. Would like your perspective
😂
You are correct. The cable is a filter, and making it longer or shorter effects just how much of a filter is it.
A woven cable like Kimber is actually better when it is longer as it's filtering more due to more crossover points
And yet even if the things you describe actually work do they make any difference it your listening experience?
@@zackschindler8334 It does.
Hi, thanks for all your informative videos. A couple of Questions:
1: If braided speaker wire works to filter out RF, which it does.( Owned Kimber Kable for nearly 12 years). Could Braided Power cables do the same thing?
2: Have you ever tested the older Polk Audio RTi As series of speakers for us poor Audiophiles? i have Polk Audio Rti A7. Thanks
The answer to question #1 is yes, and no to the second one.
A braided cable does not filter anything. This is complete bull-shit. Braiding only aids the durability of a cable, not its sound.
@@doctorfuzzzdirtbox With all due respect, do some more research on Kimber and why he braided his cable in the first place or you need to get your ears checked.
@@Rob-un6pj I've since understood the different references of braiding. Many cables are marketed as "braided" having an outer layer of cloth - primarily for aesthetics. It clear now that we're talking about braiding the cores themselves and I understand the principals of this. How Danny couldn't decifer this and point me in the right direction is now what baffles me.
Alternating current can be "dirty" due to modern electronic devices, vacuum cleaners, microwaves, chargers, florescent lights, dimmers etc etc.
The only real thing that any decent power cord might need is a thicker gauge.
You see this is why it's always "some guy from Canada with some forgettable product" that gets mentioned along with the anecdotal bedtime stories.
Because there are no disinterested parties in the audio industry. The amount of backdoor excuses baked into the cable claims are there for a reason. "Like the fact that there's no ONE SIZE FITS ALL".
Because if it was measurable and substantial it could be patented!!!
Otherwise you will just have to trust the fact that it opens up the whatchamacallit and deepens the doohickey and smells so much better than lesser power cables.
Extraordinary claims require extraordinary evidence.
But they will just make you think that you simply cannot hear it. What a shame to be you. If only you had good ears and a fat wallet, then all of your sonic dreams could come true.
So if evidence is to be believed the earth is not flat. Yet here we have someone telling us people are flat earthers because they want some evidence! Strange hypocrisy going on.
My day job includes recording relatively quiet high frequency bat echolocation calls in the 20 kHz to 70 kHz range, at wind turbines operating in low to moderate breezes (under 12 mph winds). I had an electronics engineer design a steep RLC filter for the 12 volt DC fully regulated supply powering the detectors. He is very familiar with the recording device, the power supply, and the experimental setup, and he tested it in the lab and said it provided excellent filtering and should reduce electronic noise in the detector, so I should get good recordings. I placed 6 units in 6 wind turbines and operated them for 2 nights. There was so much noise the recordings were unusable. We discussed this a length and he swore it was impossible for so much noise to enter the detector through the power supply and filter. After lots of additional R&D I determined noise was entering the recording device through the 12 V DC cable shield, so I instead switched to simple 2 conductor cable, added 2 ferrites to the 12 DC supply and it reduced the noise level enough to get usable data. The difference was 100% unusable versus usable recordings.
My second comment is that the sound improvement from good speaker cables and powerline filtering is not in the loud parts of the music. It is in the quiet parts, the room reverberations, the subtle sounds around the instruments and music. Probably less than 0.3 volt audio signals at the speakers. So distortion compared to full output is not what we're talking about, rather it is noise compared to 0.2% of full output. That's the kind of sound I record with bat echolocation calls, very quiet sounds occurring in higher noise fields. The takeaway is unless you really analyze all noise pathways and reduce the less obvious ones in the setup in question, you may not get the good results you desire. So my suggetion is to try good speaker cables and good power cords in a high resolution system, before dismissing it out of hand because there are likely other pathways for noise to get into the music's quieter passages.

Hi Danny, I am learning so much from you. I am curious why you don't use cones to seat your gear and speakers. Doesn't the vibration removal affect the sound for the better?
Well designed speaker cabinets don't vibrate much because they are stiff and heavy. The only vibrations you need to worry about are soundwave reflections. Research acoustic room treatment.
@@kmidst_mz5094 that's what I am doing, I am researching. There are some people in the community that vouch by removing any mechanical vibration from amps, crossovers, speaker isolation(hence my question).
@@andreimj Yeah I've seen that actually, amps on stands in order to angle them and such. Only high SPL bass could physically move anything around. The idea of acoustically isolating solid state gear doesn't make any sense. Like I said, speaker cabinets are designed to be acoustic isolation themselves because the speaker is a moving part. Otherwise, just the turntable needs isolation because of course vibrations mess with the needle's tracking.
We have all of our gear on that stuff. We use them with speakers some of the time. We move speakers in and out of the system so much that we often do not have them on some models.

If the Bass was audibly different between cables, couldn't someone set up a decent measurement mic and record a frequency response graph from the speakers and compare cable A to B? You could see the overlaid graphs and see if there was a difference in the freq curve between the two recordings. Is there any videos of someone doing this?
I doubt it exists, because no power cable can have such effect ... I have tried to look for some measurements supporting power cable influence, but only found some that prove that they have no effect.
Yep, I thought the host is technicality oriented so show us some measurement. If it does make noticeable difference, it got to be measurable.
You will never see that because people that believes in this nonsense the last thing they want is to actually use science to test it lol
@@shaolin95 well said
He only uses measurements for speakers, apparently.
Another manufacturer power cord sales pitch. If you add filtering, meaning active components to your
power cable you could remove noise on your line, but if you look inside your components, this circuitry is already present.
The gauge of the conductors will determine the amount of current that it will pass, more than 14 is a waist if the in wall cable and your breaker are both 15 amp rated. The insulation will determine the amount of voltage the cable can safely pass, fancy braid is for looks, and hides the actual basic internal wire/cable.
You can add shielding, this will only prevent more noise from entering the cables signal, it will not filter what is on the line from the 40+ feet of non-shielded cable in the wall.
Why don’t these manufactures supply test data to show the differences these power cables make
on the AC signal (noise, voltage, and current), they do not because they know there is no difference.
They seem to show all kinds of measurements for their crossover upgrades to show the improvements, why not their power cables?
Geez... I wonder why...
If only we could turn the AC into DC, regulate and filter it and store it in a bank of capacitors, we wouldn’t have to pay $$$ for power cables..
Oh wait
We do it with batteries. Most of our system is off the grid.
There are some pretty rude comments here. However, this video confirms my limited experience and I found it quite valuable. Keep up the good work...
How do you measure something when it's "off the charts"? 🤔
Bigger charts
Cause they are GR-Research, they can make your shitty system to be high end by using their snake oil power cable or China fake speaker cables. LOL
I see you use a lot of dc cables or hook up cables too . What do you think is 2 or 3 best dc or hook up cable? Thank you
The differences in my DC cables have been too minor to come to any conclusion on.
I am an electrical engineer. I did extensive testing on power cables from alu to copper to silver using state of the art equipment. And I could not find any difference in measurements. Now the equipment is much, much more sensitive than the human ear. My conclusion is: if the equipment cannot measure any difference, nor the ear. In my opinion a regular $10 cable sounds the same as $1000 cable. It matter the state of your mind when you listen to music.
I don't need scientific measurements to tell me anything, the only measuring tool I need in audio are my ears. My ears tell me that free generic power cord that comes with your amp should be the first thing to into the trash after you unbox.
@@arize84 absolutely. I too am an Electrical Engineer and also a trained recording studio engineer and long time audoholic. What many people forget is that science is absolutely NOT truth, its simply our best understanding of what is observable.
There is a tendency for people to dismiss observation and instead quote science to tell you what you can or cannot observe, as if science were truth, lol.
There are a whole bunch of fools who will tell you that all correctly designed amplifiers operating in their design limits will sound the same. Its clearly not true, but it also clearly demonstrates that some of the things we hear when we analyse music play back are not currently measurable, and we don't understand the mechanic which gives rise to the difference. As long as the observation meets the scientific method (repeatable blind tests) then its an observable fact regardless of if we can measure a difference or not.
Our 'electrical engineer ' clearly belongs in the group that would be stating that bumble bees cannot fly despite the fact he's getting buzzed by one xD
When thigs cannot be measured, or we don't understand the mechanic, there is a lot of room for the snake oil salesman though, and the audio industry has more than its fair share of issues with these, so extreme caution is to be advised. The only reason to replace a cable is if you can hear a difference you like when you do. I'm a big fan of cleaning up the mains signals I plug my hi fi into, and as I've spent some time with this, I've found the cable itself not to make much of a difference with my unit and my filtered and corrected mains, but everyone's situation is different.
We should take into consideration the wires in the house and in the streets, too. I mean, what difference could it possibly make, if you change only 2 meters of the total length of kilometers all the way down to the nearest transformer or powerplant? The wires of the main grid of a normal house is built based on general purposes in mind, not audiophile concepts. You might have a noisy, far from perfect sinus waveform of the mains, but can the 2 meter long power cable eliminate this noise? Should the power supply circuit of an amplifier/deck/etc. get rid of these inperfections and provide a stable DC voltage for the audio circuitry? Does the lack of noise make a wide soundstage? Does the effect of the power cable will enrich the signal with something that is not present in the original source (e.g. more treble)? And what about the less than perfect cables and other conductive materials inside the amplifier/deck/tuner/etc.? So, there is a long and complex system of wires from the powerplant to all the way to the loudspeakers. What difference could it make if you change 2 meters out of 1 km? And if it works with 2 meters, can we do it by only 5 cm long professional power cable, too? It would be cheap enough.
Bingo, it's all placebo effect and psychological.

“a fool and his money are soon parted”
But what if you add a socket adapter for either the US or UK plug? In case your country have a different type of socket. Would that have any effect on the performance of the cable?
Do you offer power cables with EU plugs, Danny.?
Not currently, but send us some and we'll build some cables out using them.
Danny , do you have Power connector with European connecter ?? , I saw on your web site , it is US type connecter
We currently do not stock that type of connector. But if you send us the connectors that you want to use then we can build out the cables using them.
Can you show us the difference in measurements? I understand that if you played us the audio we're listening on whatever speakers we have, but we would be able to at least note a difference in quality even though it's not a true representation of the sound. Without data or empirical evidence, everything you say is ultimately, untested and unscientific. Stories do not get the job done for me. I enjoy when you show before and after graphs for speaker reviews and what you did to fix them. Can nothing be done to show the difference between power cable A and B in a given setup?
Hang on.
The difference is real, it just takes an unbiased mind to have a listen. If you have already made up your mind that it won't work it will be hard for you to do a critical listening session to evaluate. You'll be saying it didn't do anything before you have even turned on the equipment. I was once skeptical that it would make a difference, how could it, it is only a power cable. But I did try it (other brands), and it did a lot of what Danny said it does.
@@bbfoto7248 He's done the tests, and even his MOM could hear the difference!
NOT.
@@DodgyBrothersEngineering Literally everything you said is backwards. The confirmation bias is you believing the cables make a difference, and then you magically hear it. But it's your brain lying to you.
@@Wizardofgosz if that was the case then my brain should have also lied to me about all the interconnects I have bought over the years. I can honestly say that I have not heard a "detectable" difference in any of them, and most have been expensive. To say I have would be wishful thinking, but power cables are a different story. There were noticeable differences from the stock power cables.
As a retired electronics tech I have to call you out on this one...If your ac power delivered to your equipment meets the voltage and current requirements the equipment requires to operate properly then there is no need for anything more and there isn't any possible way changing that power cable to some goofy expensive cable is going to make a nickels worth of difference. Using an uninteruptible power supply to keep constant voltage and to filter out spikes on the line is however a very good idea and should be used for ALL low level digital equipment. Match the size of your UPS to have 20% or so reserve capacity for the load it has to carry and you may see a lower noise floor by so doing, but I wouldn't do that with that expectation. What you will get for sure is longer equipment life and if the UPS fails to protect your equipment from lightning or some other power transient, there is a warranty in place that will replace the damaged equipment up to a pretty large number of dollars. Best insurance policy on the planet.
It might be a good thing that you retired. Your opinion is a long way from reality.
If water is traveling through 50' of 1/2" pipe, what would adding 4' of 2" pipe on the end do? NOTHING
No the last few feet of pipe under your sink is a filter. Power cables do the same thing.
@@GRResearch snake oil cow dung
@@GRResearch Prove what you say is true. Show us the measurements. Simple no? If the difference is so clearly audible then it can be measured. Prove your assertions are true. I dare you. I am calling you out as a snake oil salesman. PROVE WHAT YOU CLAIM IS TRUE OR ITS NOTHING BUT BULLSHIT.
I'm sure you didn't see the $2000 cables on other sites and Im sure you didn't make comments on their site!
should i use one of these on a vintage Marantz reciever?
Let's talk next about little wooden trestles to get the speaker cables off the floor to combat floor decoupling wavelength phase band-pass electrostatic geo interference.
haha
Noooo, they're used to keep the vacuum cleaner from tearing up the cable... everybody knows that.
Audiophiles will bite on just about anything if you tell them it will improve the sound.
Carpets contain static from people walking on them. If the cable is located directly on the carpet then static can enter the cable and effect sound. Raising the cable from the floor helps prevent this.
LOL, which idiot told you that nonsense?
I'm confused, I understand there can be noise coming from electric transmission lines. If an amplifier is able to filter its supplied power to a level that allows it to take the signal from the DAC and output it to the speakers with no distortion (and the cables to the speakers don't affect the signal) why should anything else matter?
I'm not saying none of this matters or is impossible but I'm skeptical.
I would think speaker wires acting as antennas would be a bigger problem. Surprised they aren't replaced with fiber optic cable that goes to an amp located inside the speaker, powering it directly.
Also, I keep hearing burn in. What does that mean? Do the conductive properties change as electricity runs through them?
The fact is that anytime you add a filter of any kind there is an effect. Fiber optic cable only works for digital transmission. The burn is in about what is happening to the dielectric material of the cable.
@@dannyrichie9743 when does wire burn in, the supposed changes in signal transport , start and stop?
I suppose to be thorough when touring the gear at shows would be to measure the noise on the actual outlet being used, based on your theory you should be able to best choose your wire that way.
Peachtree amp? Cherry? Is that 300B amp an Elekit? if so any upgrades?
Apple TV 😏
That is a 300B Elekit and it does have some nice upgrades inside.
I would love to see a video series in upgrading the internals of your 300b: Coupling caps, volume pot, internal wiring, transformers, etc.
I’m calling BS… If it were even remotely possible, the AC wiring and transformer inside the actual amplifier would make the difference. All of that is unshielded and within the chassis. As already said the quality of the power source and all the wiring getting to the outlet are much larger antennas.
Tried and tested before seeing this post.
It's a great improvement 👍
Good boxes always have good power supplies built in include lots filtering. It's OK to have a dedicated power conditioning device for that purpose for all boxes you got, not $$$ snake oil power cables that is NOT controllable/adjustable.
You are absolutely incorrect, but thanks for felling the need to post your opinion.
ideally the power supply in the amp and the other devices takes care of that.
How many hits have been made one cheap or normal cables versus otherwise 🤨
so, a guy selling power cords is backing power cables?
I would like to hear how the physics of braiding cable improves the filtering or is it the shielding that does it?
Braiding the cable changes the inductance and capacitance and introduces high resistance in ranges above 20kHz.
@@dannyrichie9743 CLOTH changes inductance and capacitance and effects a region of sound that we can't hear!? For Christ sake, this is sounding like flat earth theory.
@@doctorfuzzzdirtbox Changes in inductance and capacitance do change areas in ranges that we can hear.
@@dannyrichie9743 You're claiming cloth does this? And what ranges are we speaking if not above 20k?

@@dannyrichie9743 Slanderous guy too. I’m not a fan of his snooty attitude either, while basically saying you don’t know what you’re talking about, Danny, which is obviously not true. He also seems to be one of those measurements only guys, not an actual listening to the music guy. Of course, measurements are very important, but listening and how something sounds and performs is the true test.
@@r423fplip Hey, Dave. I have absolutely no problem having opposing ideas. There’s nothing wrong with a difference of opinion. You’re saying that Amir shows the truth, and Danny shows nothing, then asking who is worse. Amir’s tactics seem purely slanderous towards Danny. He’s making videos with the intention of damaging Danny’s reputation, and he does it with a pompous attitude.That’s what I don’t like about Amir. And btw, The car going the speed of light or whatever isn’t a good comparison at all, and I’ve heard you use it multiple times. It just sounds silly.
Let me ask you a serious question, and please answer it honestly. Do you just watch these vids and base your opinions on other people’s opinions, or have you actually tried different cables in your system? What about capacitors, resistors, tubes, etc.? Because I’ve heard it very clearly, I know for an absolute fact that different cables going from a turntable to a phono preamp can produce very different results based especially on capacitance, but that’s not the only factor. So, why would a cable going from your amp to your speakers not have different characteristics? They may be subtle differences, but it all adds up from your source to your speakers and it’s about fine tuning your system. I’m really not trying to be a dick either, Dave. Herb Reikert has a quote that I like that goes something like, we have the ability to hear what we can measure, but we can’t always measure everything we hear.
@@andydelle4509 Hi there Andy. I’m not saying Amir isn’t doing a service and doing it well. I watch his vids and agree with actually most of what he says, but he doesn’t seem to really truly listen. What I don’t like is his snarky nose in the air attitude, and this combative nature between TH-camrs talking badly about one another is not just healthy competition in some cases.
Believe me, I very much respect you as an EE. In fact, I am now 45, but have a huge passion for electronics and was going to go to school for it, but my mother unfortunately got sick, and I had to change things around in my life.
FWIW, when it comes to speaker cables, I use regular Canare 4S11 from Bluejeans cables. They’re well built, measure well, and sound good. For pwr cables, I just use good ol’ Belden, but was given a couple Pangea cables too. Ive also heard $1,000 cables which sounded awful. The difference between my pwr cables is negligible. Any difference I’ve heard in both my types of cables could well have been due to temperature or humidity effecting sound waves, etc. Whatever it was, it was so slight that I can’t justify or be bothered with expensive cables. Btw, my system is not crap at all, and it is plenty revealing. And yes, power quality is important, but a HiFi system obviously isn’t as important as what those UPS systems are providing power for.
In the end, my real passion in life is music, and I was fortunate enough to have toured the world numerous times for playing my guitar, but that can burn you out after years of it, so now the world of HiFi is and has been my hobby. I appreciate good music, and I enjoy reproducing it as well as I can. Have a good week, Andy. Thanks for your comment. I enjoy conversations, not arguments. ✌️🎶🌝🔊👍
@@r423fplip You really have a LOT to learn. And those Revel's are a dull and lifeless sounding speaker. If that is your reference then you may not notice much if any change of anything.
How would this translate to instrument amplifiers , bass , guitar , keyboard ect ?
