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.
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.
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.
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.
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...
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.

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....
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?
Well Danny clearly belives what he is saying. Why don't you go listlen to his system and take him up on his offer. Bring your cables and listen for the difference.

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.
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.
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,
Don't you spend money for a filter that sits under your sink to filter the water that went through miles of old pipe? The power cables acts much the same way.
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 :-)
The filtering of the power cable can't filter audio frequencies because there is no audio passing thru a power cable. This video is a snake genocide from so much oil being extracted.
My custom made cables funnel muons and quarks and make the current go faster than light. They also let me hear sounds that were not even recorded in the studio.
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.
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
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.

Danny, I usually enjoyed yor Videos regarding crossovers, but you are missing fundamental education about electronics. Sorry to say that, but you are destroying what you have built up over years with that stupid cable nonsense. Greetings from Austria
I am a vintage audio enthusiast with 20 years of experience in microelectronics. It makes me worried about the stuff Danny is talking about cables and interference. People with proper background will understand. Well, honestly, I am disappointed!!!
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.
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.
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.

There were noticeable differences from the stock power cables.

@@r423sdex Hey, Dave. I have absolutely no problem having opposing ideas. There’s nothing wrong with a difference of opinion.

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. ✌️🎶🌝🔊👍
@@r423sdex 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.
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

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.
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.
You are the flat earth guy. I hope you have a long wonderful life, but when you pass, meet your maker and are exposed to knowing all you will then know how very, very lost you were.
I question your knowledge of electricity. What size were the amplifiers? What circuit breaker size were you running? Were you running big amps on the same circuit as your DACS? You are missing something. 100% missing something... OR... your gear doesn't have proper filtering in your power sections because it is custom, OR REALLY OLD. All properly designed electronics have power filtering these days.
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"
Extraordinary claims, "the power cable made the sound open up" require extraordinary evidence. Hey, lets do a controlled double blind A B X listening test to see if you can identify which cable is being used. It's pretty easy to keep the power cable out of sight. You could even computerize the test with a few switches. Oh, switches are all so bad that they destroy the benefit of the cables, they'll all say. Better yet, how about some measurements that show a difference that's above the threshold of perception. Nope. Never gonna happen. The "audiophile" priest won't allow it. They know it is all a lie. It's just a lie that make them a lot of money.
Come over and listen for yourself. We can let you be the listener in a blind comparison. So far 100% of everyone (including skeptics like yourself) hear clear audible differences. So your skepticism really means nothing.
Wow. Lovely false equivalence between water treatment and power "treatment". It's almost embarrassing watching someone, who clearly has no idea of how electricity works, or even what electricity is, try to mangle physics to sell a completely unnecessary power cable. The specious "but I filter my water and it tastes better!" argument for power filters does not stand up to even the most cursory debunking. It's gibberish, and I'm going to be generous and assume that it was the early hour, or the cold, or a combination of the two, that led you down such a ridiculous path. For those who want to know why I'm so annoyed at the false equivalence? Remember: water is a substance (hydrogen and oxygen) in liquid form, whereas electricity is the presence or flow of charged particles. Power cords having any effect on the quality of your hi-fi is unscientific, unprovable, wooly, and any products that claim to have any effect? Pure snake oil.
Probably, but these guys are like flat earthers Even real science won't convince them the earth is a sphere because its feels flat to their feet and looks flat to there eyes. Science can't explain that man.
@@RobWhittlestone No need to. People send him expensive gear to test and listen to all the time and he has a high end system of his own. Apartmently you missed the review on $2300 cables not doing SHIT. Maybe you should look into Amir and ASR cause they have actual science and engineers testing gear not just anecdotal BS like Danny.
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...
The combination of measurements and listening which Danny does is right way to go. Experience of years makes people like Danny rule out things that just doesn't work. Matching components are widely accepted. Some speakers just go well with some components, not to say with some difficult rooms. The same way with cables. At the present moment I am having great fun and great listening experiences with just shifting from RCA's to XLR's interconnects. Can these improvements in sound quality be scientifically documented? I am not sure but I couldn't care less. I am just enjoying my self....But of course the IC's don't look anything good.. They are Anti Cables made in USA for a relatively low price... Try it out. great soundstage, punchy bass and great detail.
@@dannyrichie9743 Keep it up. If you have opened the can of worms you have to empty the whole box. Try the Anti Cables which are completely different in concept from yours. Would be a great shoot out. People love subjective shoot outs from people who know a thing or two...
So you’re able to hear 0.06db difference from a 5k speaker cable and and one from Lowes? Because that’s the difference that was measured by audioholics.
Sigh, if you're really this obsessed then get an AC regenerator which is a ac to dc rectifier mated to a dc to ac inverter. Basically ensures a pure 120v 60hz sine wave. Probably costs the same, maybe less and would produce actual measurable results on a oscilloscope.
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.
@@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.
If high end power cables would make a real difference, manufacturers of active speakers would deliver them along with the speaker instead of the standard cord or they would deliver none and leave it to you...I mean one decent studio monitor costs easily 2000 EUR, providing a 90EUR OFC or OCC power cable along wouldn't make much price difference ...yet they deliver the speaker with a standard power cord...so, obviously they don't think it influences the experience with the speaker
Power cables are better matched to a location than a piece of gear. What works great in one area might not be ideal in another. Manufacturers know this and know that people are going to use what works best for them in their application. So the standard power cable is a bit of a token jester.
@@dannyrichie9743 Why location? what changes from place to place? Why can these cables (or a power conditioner) not have some sort of variable on them to accommodate these changes?
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.
The question that needs to be asked ... Are the power supplies in this equipment so badly designed that they cannot convert, filter and regulate the DC voltages they are supplying? I would say trash the equipment that has awful power supplies. I can tell you as an engineer that designs power supplies that if the power cord negatively affects the performance of the unit, the power supply of that unit is highly dubious in terms of its design. The supply can't filter EMI on the power cord? It's a trash supply design. There is a change in current on the output of the supply due to minute line variances? It's a bad supply design. It's not the four foot cable that is the issue, it's the internal supply that is sorely lacking. A power supply is supposed to be designed in such a way where the DC voltages and current supplied to the circuits should be consistent and pure, regardless of AC line voltage conditions. Period. The only exception is where the power cord is of such a small gauge where resistive factors limits the current draw, which in the case of line level equipment, is so low where you would be talking about gauges as small as 20 gauge before a negative effect can be demonstrated. I rebuke your subjective opinion of what you perceived. The physics do not support it OR there is a severe design problem in the gear used to evaluate performance. Lastly ... this is not TRUTHS ... they are subjective OPINIONS not based on controlled objective tests and instead based on financial gains perpetrated within an industry (as you alluded to when you mentioned "hurting the industry"). I can tell you I have performed the listening test you describe many times with some audio friends. I told the people I was changing this or that and that they would hear a difference ... and they did and were excited of how obvious it was ... when in reality I changed nothing at all. So explain that. I can. Prior, I gave the usual sales pitches about "Chocolaty mid-range" and the geometry of the cable, etc before making "the change", and clearly that conditioning did it's job. My friends believed the pitch because I am a designer in the audio electronics field. In short, the variables in listening tests are so extreme as to not have any meaningful conclusive result, especially when such widespread conditioning of consumers exists in the industry. I will concede that there are some very poorly designed power supplies out there, even in very expensive gear. To all of you out there. If you perceive changes in the performance of your system by adding an expensive FILTERED cable or a power conditioner (especially the ones with no regulation or balancing) then you should be questioning the quality of the gear you have. Not spending money on a "fix" for what the gear is NOT doing; which it should be doing if designed properly. You may say to yourself, "But I like how it sounds". Ok ... but does it really sound good? If something as simple as a power cable or a conditioner can change the sound, what is your metric for it sounding good in the first place. Clearly something is not right with the gear. You said at the beginning that power cables do not impact amplifiers as much. Why is that the case? Well ... the simple and factual answer is that amplifiers REQUIRE substantial power supply design in order to perform their most basic functions. I'll say it again, amplifiers must have properly designed supplies. So what you said is correct, but not for the reasons you imply. Not doing the science? Measuring the wrong things? Did you actually say that? Shame on you. As an engineer (in the audio business BTW) I can attest with certainty subjective listening (observation alone) is not science, since it is subject to confirmation bias, a big no-no in science. What I will say Dan is this ... I believe you are being sincere in describing what you perceive ("perceive" being the operative word here); however, I have to point out the last 6 minutes of the video are nothing but a sales pitch to your viewers. My hope is that you are not being disingenuous with your viewers.
Anyone that believes that any well designed power supply is going to filter out everything is naive. Adding a filter of any kind will have an effect. Even the best gear is still affected. I have had companies swear that their power supplies in their amplifiers are supper well designed and need nothing but the supplied cables. Those are the amps that are typically affected the most. If they don't think adding filtration will have no affect on their gear then they have no idea what they are doing. Secondly, I have had a lot of guys over that think very much like yourself, and swapped something out without even telling them what I did. They hear an audible difference immediately and explain the differences accurately. They are also really surprised to find out it is a power cable, USB cable, or a firewire cable.
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.
These snake oil power cables are pure nonsense and do more harm that good. All cables CANNOT improve the sound of your system but to carry the information from one component to another FAITHFULLY. Every electronic component is designed with a dedicated filter in the power supply circuit and any external filter is a joke. For the sake of natural sound in music, I wish more audiophiles can look into this seriously.
Then all “dedicated” power supply circuits would have been standardized decades ago. They have Not. And upgrading the manufacturer's external pwr sups shouldn't make a difference either. But it does.
Because no science supports his statements. And did you notice he did not show us what happened to the waveform as it went through those coils? Distorting the magnetic field results in a distorted signal. He only showed you how much was induced across coils as he distorted the magnetic field - not what happened to the signal itself.
Even the wire is wire guys have no idea how to measure and quantify the differences that we hear in cables. As they say, the proof is in the pudding. And we can clearly hear the differences.
@@toneysunny9283 It would be quite impossible to do A-B comparison tests via youtube due to the lossy audio compression. Let alone the millions of different hardware of varying quality on our end. Which leaves us with only that which can be measured objectively. And testimonials 'ain't it.
WOW!!! Equating Water delivery with Electrical Power delivery. Brilliant!!! Versus Audio Science Review (misnomer as there is no science in 100% denial that cables make no sonic difference, even when Amir measures them the same).
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’?👍🍻
Yep, I thought the host is technicality oriented so show us some measurement. If it does make noticeable difference, it got to be measurable. "Don't fall victim of this snake oil" like Audioholics says.
Burn in time for a power cable? LOL! You mean "Use them long enough so you are outside of the return window before you try to return them"... And given you are asking $350 for a piece of wire, why don't you "burn them in" first? Maybe we should get them cryogenically treated to align the molecules? Or have them sent into space orbit for at least 2 trips around the earth?
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.

Prove it. Show us the pre & post outputs on an oscilloscope from these magic power leads. Show us audio spectra from different sources with & without these power cables. All you've given us is unverifiable anecdotal evidence. How can over-filtering cause a 'dull' soundstage? The maximum you can achieve is a pure sinewave - how is that detrimental?

I'm at odds with the information in this talk, despite my utter respect to Mr. Danny Richie. If a mere cable can make such a difference, I can only see one possible explanation: the PSU in this amp/DAC/player is a piece of crap. I have seen/heard a lot of talk among audiophiles on cables, but I have never seen a SINGLE measurements showing any difference, and I have not heard of a SINGLE blind A/B comparison.
@@dagnisnierlins188 You mean Audio Theory Review? They do no science over there. They just theorize what will make an audible difference and what will not.
Most electronics attempt some level of filtering, because A/C noise is a problem. Most are fairly week filters or low order filters. Noise levels can go up but filtering doesn't change. So a lot of it passes right through.
@Douglas Blake Yes, that noise effects the audio signal. That is why just about every piece of gear out there tries to address some of it to some degree. And I just got a call from a customer a few minutes ago telling me how much the power cable transformed his system. He said it made more difference in his system than any other piece of gear. Then he ordered two more of them. And then I have guys like you that have never heard anything trying to tell me and everyone else how something will sound. You should quite talking and do some listening.
This guy makes a living by selling upgraded components that "purify and clarify" sound. Is it a surprise at all he's pushing some Hocus pocus non-scientifically verified garbage?
I just use a really short power cable. But I might buy a really long expensive cable that will improve the sound a lot. I will invest in a scarecrow as the birds on the power lines are affecting my soundstage. All my favourite musicians have received complimentary high end power cables for their recording equipment. The cables match my ones and the sound is so much better now.
Abject nonsense. What next? Gold plated fuses? 'Sound is better if you rotate your amp by 90 degrees' Sound is better if you polish your cables. In reality the biggest improvement in sound due to using expensive 'interconnects' is delusional perception. How tired you are, your mood, what you've eaten, what you've drunk, what you've smoked(!), the power of suggestion. None of these objectively affect sound quality. Any 'improvement' my friend is due to your brain. But hey, maybe I'm wrong, perhaps if I boil my kettle with a $200 power lead maybe my coffee will taste twice as good.
Some people apparently like to eat baloney. Facts seem to cause indigestion and indignance. Texas....isnt that where they are having a "fraudit"? Could it be something in the water? Lol
@@Boskibro you guys are really ignorant and that's the only reason your behavior is excusable. Power cables DO make a difference but you need the right system first. If cabling isn't your bottleneck then your prolly not gonna hear a difference. Go look at most high end audiophile forums and you look at the guys that have been doing this prolly longer than most of you have been alive and not all but most of them spend thousands of dollars on cabling. Why? Because on the higher end systems it can make enormous differences just like Danny is talking about. It's happened with me. I'm not imagining things! I listen to a reference playlist and know these songs like the back of my hand on my system. When I added power cables the sound signature changed everywhere for the better. Period!
Rule of thumb! Speaker, Speaker Speaker! Invest on your speakers, don't just spend money on stupid snake oil cables, especially when someone goes "wow once I plug in my cable it opens up the, so dead silent, so dark, so much clarity. Speaker cables, Interconnect, power cords are like ingredients. Minor changes. It will not bring your shitty systems back to life like a high end systems. Don't let people fool you. Doesn't matter if you are using CH Precision, Jeff Rowland.....etc.... if you have a pair of bad speakers, your sound will stay suck deep inside the black hole LOL.
Power cables are snake oil pure and simple. There can be no discussion here. Perceptual bias is responsible for differences you are hearing. I just discovered your channel and I am at a loss for the misinformation you are spreading. Go to Amir's channel for the TRUTH about this stuff. Again, you will hear differences in stuff if you are conditioned too... putting pennies on your fridge will not make the food taste better, unless you believe it does, and then it will. That is the power of perceptual bias.
You are significantly mistaken. There is not truth to be found over there. Nothing but misinformation based on theory and speculation. If you want to learn the real truth then this is the place to be.
So what you are saying is that when the electronics have proper filtering on the supply input you don't need to spend $350 on one of the cables you sell.
Danny your really trying to push your Cable Agenda to the point of having a Nervous Breakdown please do yourself a favor and go to Audioholics Gene's giving a tutorial today on cables!!!
Welcome to the ongoing world of the Church of Danny. Danny science can say anything....but don’t you dare disagree else you will be excommunicated! If you instead want to see what really matters, instead of Danny’s “suck the life right out of your wallet” nonsense, then you could consider a TH-cam channel that actually follows science, like the recently started and insanely fast growing audio science review TH-cam channel. You won’t find arrogant nonsense there, and you will actually learn useful stuff.
Ok, 40 years in electrical engineering and without data these 22 minutes really mean nothing. I jumped around and like most things that are hifi it is subjective and usually overpriced. I am not saying that everything is hokum, it is not. When you are starting at the bottom any minor change could be a huge improvement. After that it flattens out very quickly. Now just so you know my setup is not entry level, my speakers Sonas Faber Cremona's were almost $10,000. My CD play is an Esoteric, that was another $5000, turn table, phono stage, amps are all the same caliber. So, I have about $+30K into this thing, and when we experiment and mix and match cables occasionally there may be a very slight change, but most of the time it is the listener's head. One more thing, a few years back a friend of mine and I were considering purchasing a Hifi cable manufacture, who received good reviews and he sold these cables in his shop and they weren't cheap. We flew out to see the facility and how they were being manufactured, it turned out they were nothing special. It was just Belden and Alpha wire with some expandable braid and nice connectors. If it sounds good to you and you have the money to spare go ahead and get the cables. It is a hobby and very personal. Otherwise show me data and then I may consider auditioning them.
Microphones don't easily pick up the changes that the cables bring to the table. Chris explained it pretty well: th-cam.com/video/AaSpc7GOjxA/w-d-xo.html

All you guys do is guess. Can you at least reference some type of scientific theory that would somehow imply that a cable can't make a difference in sound quality? I highly doubt it. For the last 30 years I've been asking the exact same questions to people like you. I have never gotten an answer of any kind. Not one time. You guys either run, or you ramble on about something that sounds complicated, but doesn't mean anything. Maybe you'll be the first?
Sorry , but expensive power cords are a hoax. If you have noise coming from the mains , you have a problem with your amp because the power supply , if designed properly , should eliminate all noise. No power cord , no matter how expensive , will eliminate noise.
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 )

With all due respect to your belief, why does a company whose amplifier costs, say, 5000 euro/dollar, provide a 10-15 euro/dollar power cable with the amplifier? That the amplifier works worse?

Come on, please
Companies send out a token power cable worth nothing because they know that the customer is going to use a power cable of their choice and one that is best for their location. Power noise levels are different every where you go. If you really want to witness really bad power, go to a show at a hotel.
@@dannyrichie9743 Then why do these same companies often state in their manuals or warranties to "only use the supplied power cable" with their products? Why would does a Neve studio console not come with the specialist IEC that sounds best with that product? Why does it still come with a standard, moulded, off the shelf kettle plug? For the huge price tag, is adding perhaps a little extra investment to the whole package not in their best interests to have their products sound as best they can from the first moment of use?
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.
Won't happen. The argument boils down to, noise exists, these cables do things to reduce said noise that expensive and high quality components cannot do, people can hear the differences enabled by this lack of noise even though neither the noise nor changes to the audio signal are measurable through any known equipment, even though said equipment is MANY times more sensitive than the human ear. Therefore the proof lies in listening, and only in listening. I was hoping to at least get some reasonable debate as to why the noise and/or audible changes aren't measurable through any type of analyzer, but nothing.
@@redstang5150 The fact that psychics exist doesn't mean that everyone is similarly gifted. That's what a subjective analysis would indicate. So, if you are blessed with a bat's hearing, that does mean YOU are exceptional. When we mass market a product, it isn't for those exquisite organs mounted on YOUR head, it's for the herd. While I won't contend that mediums don't deserve a Steuben Crystal Ball, it doesn't mean many others requires similar quality in their display cabinets. When we get into subjective analysis , you can still use blind testing. Those results can be tabulated. If spooky psychic stuff isn't in your bag, try a bunch of theoretical physicists discussing esoteric theorems in front of folks who have degrees in the humanities. To the crowd it's noise. To the talking heads, it's meat and potatoes. I've sold enough product to enough different people to state that the most annoying folks to convince to 'just buy the damn thing' is the crowd who BELIEVE they can distinguish fine granulations in the sound. The ones who CAN discern those minute differences have no difficulty in deciding where to put their money. That last class of consumers is RARE.
@@dennisbohner6876 I'm not sure I get your point. Are you making the golden ears argument? Or are you proposing there is a way to objectively measure some of these things? Your original comment wasn't about blind testing but you now bring it up so not sure of your position. My problem has been with the arguments put forth so far in these videos that take a nugget of truth but then twist it into something irrelevant when it comes to applying it to the real and known science that applies the use case. He knows what he is talking about isn't measurable so he just talks about experiences. His proof is in the listening and offers nothing beyond that. Fine. What frustrates me is that instead of acknowledging the reality of every counterpoint mentioned by someone in any of these comments and debating that directly or admitting those things are relevant and also true, is he rejects educated/experienced people using known science as being "flat earthers" which is ridiculous. And I am open to the possibility that there IS something going on here that is more than confirmation bias, so unlike most, I don't approach this as though he's simply making this all up to sell cables. He's an experienced guy - I thought he might address the topic differently. So in the end we're not getting anything more from this than, come to my room, you'll hear it for yourself. Or buy my cable and try it, it has a money back guarantee. While he has made a few comments that I found interesting and are much more measured and realistic than other cable pundits, in summary there's nothing new there.

Do for me some blind testing of a non-select group of folks off the street. Do the max set of equipment to make sure if detection of differences is statistically reliable, people like me wouldn't say 'It's more Bose BS'.
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.
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.

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.

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.
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.
Still enjoying your cable? 😂
I got the joke, though.
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.
I have a nice Cardas headphone cable. It’s expensive but I got it used for around $90. It probably doesn’t improve the sound but I like the look of it
Lmao!! Brilliant
LOL....🤣🤣🤣🤣
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.

Absolute nonsense. You should learn some basic electrical theory.
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.
The difference between believing and knowing is experience 😁
Bingo, I love when actual experts weigh in on this bs snake oil.
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! ;)
Cables can be configured to act like a filter just like those that filter water.

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.
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.

@@j.t.cooper2963 Not a problem. We just made one.
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.

Don't you spend money for a filter that sits under your sink to filter the water that went through miles of old pipe? The power cables acts much the same way.
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!

@@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 :-)
The filtering of the power cable can't filter audio frequencies because there is no audio passing thru a power cable. This video is a snake genocide from so much oil being extracted.

You sound like a guy who's never heard a tube amp
My custom made cables funnel muons and quarks and make the current go faster than light. They also let me hear sounds that were not even recorded in the studio.
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.

@@MrDannydjmix2 against their religion.
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.
Nice crossovers but this is a joke. 🤦♂️
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.
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.

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...

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.
"Not a lot of money"
"Couple hundred bucks"
Literally a piece of wire.
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.
23 minutes of crap!
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.

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.

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 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.

@@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.

Anyone spouting off the words "double blind testing" doesn't know how A/B comparisons work or how they are conducted.
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.

@@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.

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.

You are missing something. 100% missing something... OR... your gear doesn't have proper filtering in your power sections because it is custom, OR REALLY OLD. All properly designed electronics have power filtering these days.
Regardless of your gear, power conditioning can still have some effect.
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.
Where are you measurements when you prefer the sound of one speaker over another; no difference. The ears are the ultimate Judge.

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.

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.

@@willbrinklike I said Baloney to your narrow minded thoughts. Be Gone
Extraordinary claims, "the power cable made the sound open up" require extraordinary evidence. Hey, lets do a controlled double blind A B X listening test to see if you can identify which cable is being used. It's pretty easy to keep the power cable out of sight. You could even computerize the test with a few switches. Oh, switches are all so bad that they destroy the benefit of the cables, they'll all say. Better yet, how about some measurements that show a difference that's above the threshold of perception. Nope. Never gonna happen. The "audiophile" priest won't allow it. They know it is all a lie. It's just a lie that make them a lot of money.
Come over and listen for yourself. We can let you be the listener in a blind comparison. So far 100% of everyone (including skeptics like yourself) hear clear audible differences. So your skepticism really means nothing.
Meanwhile back at the Bar or auditorium or tv station they use the very cheapest cables / cords they can get buy with to ORIGINATE / mix the sound.
Wow. Lovely false equivalence between water treatment and power "treatment". It's almost embarrassing watching someone, who clearly has no idea of how electricity works, or even what electricity is, try to mangle physics to sell a completely unnecessary power cable. The specious "but I filter my water and it tastes better!" argument for power filters does not stand up to even the most cursory debunking. It's gibberish, and I'm going to be generous and assume that it was the early hour, or the cold, or a combination of the two, that led you down such a ridiculous path.
For those who want to know why I'm so annoyed at the false equivalence? Remember: water is a substance (hydrogen and oxygen) in liquid form, whereas electricity is the presence or flow of charged particles. Power cords having any effect on the quality of your hi-fi is unscientific, unprovable, wooly, and any products that claim to have any effect? Pure snake oil.
YES.

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.

The combination of measurements and listening which Danny does is right way to go. Experience of years makes people like Danny rule out things that just doesn't work. Matching components are widely accepted. Some speakers just go well with some components, not to say with some difficult rooms. The same way with cables. At the present moment I am having great fun and great listening experiences with just shifting from RCA's to XLR's interconnects. Can these improvements in sound quality be scientifically documented? I am not sure but I couldn't care less. I am just enjoying my self....But of course the IC's don't look anything good.. They are Anti Cables made in USA for a relatively low price...

Sigh, if you're really this obsessed then get an AC regenerator which is a ac to dc rectifier mated to a dc to ac inverter. Basically ensures a pure 120v 60hz sine wave. Probably costs the same, maybe less and would produce actual measurable results on a oscilloscope.
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.

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?
Total bs how about some real measurements and show us.

@@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!
If high end power cables would make a real difference, manufacturers of active speakers would deliver them along with the speaker instead of the standard cord or they would deliver none and leave it to you...I mean one decent studio monitor costs easily 2000 EUR, providing a 90EUR OFC or OCC power cable along wouldn't make much price difference ...yet they deliver the speaker with a standard power cord...so, obviously they don't think it influences the experience with the speaker
Power cables are better matched to a location than a piece of gear. What works great in one area might not be ideal in another. Manufacturers know this and know that people are going to use what works best for them in their application. So the standard power cable is a bit of a token jester.
@@dannyrichie9743 Why location? what changes from place to place? Why can these cables (or a power conditioner) not have some sort of variable on them to accommodate these changes?
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.
The question that needs to be asked ... Are the power supplies in this equipment so badly designed that they cannot convert, filter and regulate the DC voltages they are supplying? I would say trash the equipment that has awful power supplies. I can tell you as an engineer that designs power supplies that if the power cord negatively affects the performance of the unit, the power supply of that unit is highly dubious in terms of its design. The supply can't filter EMI on the power cord? It's a trash supply design. There is a change in current on the output of the supply due to minute line variances? It's a bad supply design. It's not the four foot cable that is the issue, it's the internal supply that is sorely lacking. A power supply is supposed to be designed in such a way where the DC voltages and current supplied to the circuits should be consistent and pure, regardless of AC line voltage conditions. Period.
The only exception is where the power cord is of such a small gauge where resistive factors limits the current draw, which in the case of line level equipment, is so low where you would be talking about gauges as small as 20 gauge before a negative effect can be demonstrated. I rebuke your subjective opinion of what you perceived. The physics do not support it OR there is a severe design problem in the gear used to evaluate performance. Lastly ... this is not TRUTHS ... they are subjective OPINIONS not based on controlled objective tests and instead based on financial gains perpetrated within an industry (as you alluded to when you mentioned "hurting the industry"). I can tell you I have performed the listening test you describe many times with some audio friends. I told the people I was changing this or that and that they would hear a difference ... and they did and were excited of how obvious it was ... when in reality I changed nothing at all. So explain that. I can. Prior, I gave the usual sales pitches about "Chocolaty mid-range" and the geometry of the cable, etc before making "the change", and clearly that conditioning did it's job. My friends believed the pitch because I am a designer in the audio electronics field. In short, the variables in listening tests are so extreme as to not have any meaningful conclusive result, especially when such widespread conditioning of consumers exists in the industry. I will concede that there are some very poorly designed power supplies out there, even in very expensive gear.
To all of you out there. If you perceive changes in the performance of your system by adding an expensive FILTERED cable or a power conditioner (especially the ones with no regulation or balancing) then you should be questioning the quality of the gear you have. Not spending money on a "fix" for what the gear is NOT doing; which it should be doing if designed properly. You may say to yourself, "But I like how it sounds". Ok ... but does it really sound good? If something as simple as a power cable or a conditioner can change the sound, what is your metric for it sounding good in the first place. Clearly something is not right with the gear.
You said at the beginning that power cables do not impact amplifiers as much. Why is that the case? Well ... the simple and factual answer is that amplifiers REQUIRE substantial power supply design in order to perform their most basic functions. I'll say it again, amplifiers must have properly designed supplies. So what you said is correct, but not for the reasons you imply.
Not doing the science? Measuring the wrong things? Did you actually say that? Shame on you. As an engineer (in the audio business BTW) I can attest with certainty subjective listening (observation alone) is not science, since it is subject to confirmation bias, a big no-no in science. What I will say Dan is this ... I believe you are being sincere in describing what you perceive ("perceive" being the operative word here); however, I have to point out the last 6 minutes of the video are nothing but a sales pitch to your viewers. My hope is that you are not being disingenuous with your viewers.
True .....I've heard the same thing from many people
Anyone that believes that any well designed power supply is going to filter out everything is naive. Adding a filter of any kind will have an effect. Even the best gear is still affected. I have had companies swear that their power supplies in their amplifiers are supper well designed and need nothing but the supplied cables. Those are the amps that are typically affected the most. If they don't think adding filtration will have no affect on their gear then they have no idea what they are doing.
Secondly, I have had a lot of guys over that think very much like yourself, and swapped something out without even telling them what I did. They hear an audible difference immediately and explain the differences accurately. They are also really surprised to find out it is a power cable, USB cable, or a firewire cable.
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.
These snake oil power cables are pure nonsense and do more harm that good.
All cables CANNOT improve the sound of your system but to carry the information from one component to another FAITHFULLY.
Every electronic component is designed with a dedicated filter in the power supply circuit and any external filter is a joke.
For the sake of natural sound in music, I wish more audiophiles can look into this seriously.
Then all “dedicated” power supply circuits would have been standardized decades ago. They have Not. And upgrading the manufacturer's external pwr sups shouldn't make a difference either. But it does.

Yep, I thought the host is technicality oriented so show us some measurement. If it does make noticeable difference, it got to be measurable. "Don't fall victim of this snake oil" like Audioholics says.
so, a guy selling power cords is backing power cables?
Burn in time for a power cable? LOL! You mean "Use them long enough so you are outside of the return window before you try to return them"... And given you are asking $350 for a piece of wire, why don't you "burn them in" first? Maybe we should get them cryogenically treated to align the molecules? Or have them sent into space orbit for at least 2 trips around the earth?
Nope there is plenty of time to burn them in, give them a listen and still return them if you want.
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.

@Douglas Blake Yes, that noise effects the audio signal. That is why just about every piece of gear out there tries to address some of it to some degree.

I am not saying that everything is hokum, it is not. When you are starting at the bottom any minor change could be a huge improvement. After that it flattens out very quickly. Now just so you know my setup is not entry level, my speakers Sonas Faber Cremona's were almost $10,000. My CD play is an Esoteric, that was another $5000, turn table, phono stage, amps are all the same caliber. So, I have about $+30K into this thing, and when we experiment and mix and match cables occasionally there may be a very slight change, but most of the time it is the listener's head. One more thing, a few years back a friend of mine and I were considering purchasing a Hifi cable manufacture, who received good reviews and he sold these cables in his shop and they weren't cheap. We flew out to see the facility and how they were being manufactured, it turned out they were nothing special. It was just Belden and Alpha wire with some expandable braid and nice connectors. If it sounds good to you and you have the money to spare go ahead and get the cables. It is a hobby and very personal. Otherwise show me data and then I may consider auditioning them.
I just like to see these opinions with science facts. When ears can "hear" a difference surely a good mic can measure a visable graph.
Yes.
Microphones don't easily pick up the changes that the cables bring to the table. Chris explained it pretty well: th-cam.com/video/AaSpc7GOjxA/w-d-xo.html
@@bren1886 I call BS. We have devices that can sense the slightest Nuance in sound. I've heard people say that one time we couldn't prove gravity, but we knew it existed. Just hearing something doesn't mean it's really there. We fill in the gaps with our brain, we literally hallucinate a lot of the sounds. What we expect is what we get. If we spend thousands of dollars on cables we are going to convince ourselves that sounds better..
The truth is, there's a reason you will never see side-by-side comparisons doing blind tests. The few people who do them come to the conclusion there is no difference between power cables.
Most of the guys are just going to tell you it "sounds better to them" and that's good enough for them. And that's fine. As long as they aren't trying to convince other people to buy that crap
@@bren1886 You're right, but taking measurements isn't doing science. Its junk science. Don't let them suck you into trap. They couldn't do science if they're life depended on it. Read my next post to see what I'm talking about.
@@carpo719 I call BS on your statement. You don't have a shred of evidence to back up. You may not believe he can hear a difference between power cables, but that's more evidence than you'll ever have.
"The truth is, there's a reason you will never see side-by-side comparisons doing blind tests. The few people who do them come to the conclusion there is no difference between power cables."
BS. The truth is you have never done a scientifically valid test. Its also true that you could never reference a well done listening test of any kind, done on any kind of cable, not just power cords. All you guys do is guess. Can you at least reference some type of scientific theory that would somehow imply that a cable can't make a difference in sound quality? I highly doubt it. For the last 30 years I've been asking the exact same questions to people like you. I have never gotten an answer of any kind. Not one time. You guys either run, or you ramble on about something that sounds complicated, but doesn't mean anything. Maybe you'll be the first?
Sorry , but expensive power cords are a hoax. If you have noise coming from the mains , you have a problem with your amp because the power supply , if designed properly , should eliminate all noise. No power cord , no matter how expensive , will eliminate noise.
You are absolutely incorrect, but thanks for felling the need to post your opinion.
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 )
True Lajos, this guy is a sales man, plain and simple.
Just... no.
Nelson Pass does not use those fancy look cords .. Neither Bryston. All makes top notch amps
Nelson Pass happens to be very few people with Integrity left in the industry not pushing one snake oil after another that gullible and insecure sheeps fall for.
John Dunlavy was another but got ostracized by peers for exposing snake oil money grab scams.
I love the believers who believe such nonsense and dont even know the correct sound of an instrument to begin with It' such a fad to believe. These people are not even musicans!! These people are more in love with their audio systems than they are with music and lastly they are in total denial of the results of A, B, X, testing which negates everything they claim.
Actually the A/B testing confirms the differences. And we have quite a few musicians working at GR Research.
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
If a power cable makes a difference on the sound of your amplifier the power supply part of that amplifier is badly engineered.
A filter always has some effect regardless. That's a fact.
Fancy cables are just that, fancy cables. Just use quality cables (50 dollar ones, not 5000) and everything will be fine.
That is perfectly fine for yourself, but why are you trying so hard to make everyone else believe in your religion? If your happy with the performance of system, why does it matter if others want more from their rigs?
@@ericharrelson2045 Religion? Trying hard to convert others? What the heck are you talking about?

truly crazy snakeoil
Dear lord. Don't you know this is the Third Rail of Audio Vlogging?
Do you fear nothing!?
With all due respect to your belief, why does a company whose amplifier costs, say, 5000 euro/dollar, provide a 10-15 euro/dollar power cable with the amplifier? That the amplifier works worse?
How gullible audiophiles are, the video on YT shows, thousands of euro/usd were spent on cables, lifters, isolation platforms etc etc etc...and he put a trumpet (a metal instrument!!!!!!!!) on the speaker.
Come on, please
Companies send out a token power cable worth nothing because they know that the customer is going to use a power cable of their choice and one that is best for their location. Power noise levels are different every where you go. If you really want to witness really bad power, go to a show at a hotel.
@@dannyrichie9743 Then why do these same companies often state in their manuals or warranties to "only use the supplied power cable" with their products? Why would does a Neve studio console not come with the specialist IEC that sounds best with that product? Why does it still come with a standard, moulded, off the shelf kettle plug? For the huge price tag, is adding perhaps a little extra investment to the whole package not in their best interests to have their products sound as best they can from the first moment of use?
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. 🤷🏻♂️
@@rayl3028 Hmm, there's links to buy cables in the video description. Interesting coincidence.
.... 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.
We’ll to bad for you that audioholics busted this myth. But they do look nice
Nope, they have done nothing.
Show the numbers with an analyzer. Please. AudioScience does and he disputes what you are saying in a very thorough manner.
Won't happen. The argument boils down to, noise exists, these cables do things to reduce said noise that expensive and high quality components cannot do, people can hear the differences enabled by this lack of noise even though neither the noise nor changes to the audio signal are measurable through any known equipment, even though said equipment is MANY times more sensitive than the human ear. Therefore the proof lies in listening, and only in listening.
I was hoping to at least get some reasonable debate as to why the noise and/or audible changes aren't measurable through any type of analyzer, but nothing.
@@redstang5150 The fact that psychics exist doesn't mean that everyone is similarly gifted. That's what a subjective analysis would indicate. So, if you are blessed with a bat's hearing, that does mean YOU are exceptional. When we mass market a product, it isn't for those exquisite organs mounted on YOUR head, it's for the herd.
While I won't contend that mediums don't deserve a Steuben Crystal Ball, it doesn't mean many others requires similar quality in their display cabinets.
When we get into subjective analysis , you can still use blind testing. Those results can be tabulated.
If spooky psychic stuff isn't in your bag, try a bunch of theoretical physicists discussing esoteric theorems in front of folks who have degrees in the humanities. To the crowd it's noise. To the talking heads, it's meat and potatoes.
I've sold enough product to enough different people to state that the most annoying folks to convince to 'just buy the damn thing' is the crowd who BELIEVE they can distinguish fine granulations in the sound. The ones who CAN discern those minute differences have no difficulty in deciding where to put their money. That last class of consumers is RARE.
@@dennisbohner6876 I'm not sure I get your point. Are you making the golden ears argument? Or are you proposing there is a way to objectively measure some of these things? Your original comment wasn't about blind testing but you now bring it up so not sure of your position.
My problem has been with the arguments put forth so far in these videos that take a nugget of truth but then twist it into something irrelevant when it comes to applying it to the real and known science that applies the use case. He knows what he is talking about isn't measurable so he just talks about experiences. His proof is in the listening and offers nothing beyond that. Fine. What frustrates me is that instead of acknowledging the reality of every counterpoint mentioned by someone in any of these comments and debating that directly or admitting those things are relevant and also true, is he rejects educated/experienced people using known science as being "flat earthers" which is ridiculous. And I am open to the possibility that there IS something going on here that is more than confirmation bias, so unlike most, I don't approach this as though he's simply making this all up to sell cables. He's an experienced guy - I thought he might address the topic differently.
So in the end we're not getting anything more from this than, come to my room, you'll hear it for yourself. Or buy my cable and try it, it has a money back guarantee. While he has made a few comments that I found interesting and are much more measured and realistic than other cable pundits, in summary there's nothing new there.
@@redstang5150 I don't have a Bugatti. I can appreciate the numbers that it generates as to performance but I also know I could never achieve those numbers myself. Hell, my 'vettes trumped any semblance of professional ability that I have.
They were great cars but testing their limits was beyond me.
I think the same qualification exist for any sane purchase by 'normals'. You have fifty grand in a stereo, MAYBE it's sensible but not for the majority.
Do for me some blind testing of a non-select group of folks off the street. Do the max set of equipment to make sure if detection of differences is statistically reliable, people like me wouldn't say 'It's more Bose BS'.
Similar to religion. If you believe in it, it really works. Lol. It's your money...
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.
This is the longest advertisement I’ve ever seen for his company
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?
