Because of your videos Inakustik is going to the top of my must try cable companies. Seems like they are fairly hard to find in the US. Can you point us to a website that sells domestically? The whole issue of DC on the line has never been explained so clearly. Literally some electronics don't use half the sine wave which causes asymmetry! Never realized that is what is going on. As for filtration of power I agree most power amps sound better straight into the wall (I know mine does) but front-ends, especially digital, really need some filtration to sound their best. Really looking forward to Inakustik's listening test they mentioned of their 4500 power conditioner v. a Home Depot power strip! Great stuff!
Thanks...You can contact Bob at Worldwide sales for North American distribution. Send me an email and I can give you his number (email is in the description)
Love your audio info. Fashion choices not so much, but cool that you are comfy showcasing your unique tastes. I am impressed with the Inakustik tour. These are smart serious people. I agree with their approach to power filter/conditioning. I found that inductors kill sound. Modest capacitance to remove high frequency noise is helpful, and DC blocking is best of all.
Just send me an email (in the description of my videos). I can put you in touch with the mfg or distributor where they do custom outlets based on your needs. You might have missed the part where they said they sometimes do 6 analog outlets or 6 digital outlets if that is what's required.
Good video, but shame there is little or no evidence for power cords or interconnects making any sonic improvement , in fact the opposite can’t be shown
I'll get to the listening tests in their reference room in a future video. One test was pretty dramatic. We'll also do the lab in an upcoming video that talks about measurements. Whether you can hear a difference or not will depend on many factors... Real or imagined... But I'm highlighting tons of other metrics that should be considered regardless if you can hear differences sonically.
@@AudiophileJunkie power cord improvements shows a complete lack of understanding how audio products operate They convert AC to DC ie AC distortion is filtered out that’s why it’s dc so nothing before the conversion to DC. Matters , unless you power supply is appallingly bad in which case no power cord will help your just imagining differences as no pc has the filtering of an ac to dc power supply it’s expensive junk imho and I own lots of expensive pc and there is no difference from an engineering point there can’t be and no filtering of ac will make any significant difference in distortion as they just don’t have enough filtering capacity that why your audio device has big capacitors in its power supply and power conditioners don’t it’s not magic just common sense electrical engineering lol
I think you are reciting just one argument, but forgetting about many other things. I agree that the SQ should be minimal to none if based on some "filtering" rationale. The key is not filtering or overall SQ improvement. The most common issue I've found is more niched. Many cords and connectors are subpar in either gauge or quality of connection. You can see this even with charging cords for your phone when one cord will show "slow charging" and others will show fast charging. It's the quality of the connection and cable that is the only thing changing. If you run numbers like some have...here's just one example...a typical 6-foot 14 AWG rubber cord and 25 feet of ROMEX has inductance of 7.2 uH and resistance of 235 mohms, ignoring the plug resistance effect. Therefore, the voltage drop at 20kHz will be I*(wL+R)= I*(.905+.235) = I*(1.14). With a 6-foot low-inductance cord and 25 feet of ROMEX, the inductance is 5.9 uH and the total resistance is 147 mohms. This is an 18% reduction in inductance and a 37% reduction in resistance. The voltage drop for this combination will be I(wL+R) = I(.741+.147) = I(.888). So at a fixed dynamic current I, the voltage drop in the entire power feed at 20kHz is 22% smaller with the low-inductance power cord. That amount could be significant and audible during high current transients, but there are countless other variables too. I'm not using that example to say you will DEFINITELY HEAR a difference, just like you can't say you CAN'T hear a difference based just "filtering" logic. You have to assess a ton of different variables and situations including the lengths, connectors, gauge, and even age of what you cables you are comparing...not to mention the quality of the gear. Are you also assuming all power supplies are the same quality? You may be correct that a change in cords won't make a difference you can hear, but primitive arguments to generalize for all scenarios isn't "science" either. We're not even talking about the SQ of power cords in this video though. We're talking about certifications, safety and reliability of power conditioners mainly. It's fine if you have zero standards for those elements too, but the audibility of power conditioners is pretty obvious if you've ever tried to hook up an amp to one. I'm not saying that the SQ is an improvement either. If you can't hear the deleterious effects of most power conditioners on amplifiers, then I'm not sure what to tell you.
@@AudiophileJunkie yes there is a difference in the voltage drop between the two but the voltage drop even with the cheap chord is not significant with short runs so 22% isn’t not really important and your quoting at 20 kHz which most cannot even hear and in most extreme situations Agree reliability and safety are important but most power cords from Amazon have safety certification and u should not buy power cords that don’t
That's fine but you're again making assumptions and generalizations about length to fit the narrative. You can obviously get a quality power cord cheap, but it may not look great for your standards... On the flip side, you could get ripped off by a great looking cord that's expensive, but cheaply made. The issue is that I'm not featuring either of those scenarios. I'm featuring a very high end mfg of cables that includes all the metrics that people may value in a high end cable... And they make them for virtually every budget range, so getting triggered by this video is peculiar...as are the generalizations and assumptions needed to keep the narrative going, while remaining inapplicable to anything shown or said in the video.

Worldwide Wholesales sells Inakustic. I have a Inakustic 3500P Power conditioner for sale if you are interested. I have the 4500P now.
Just incredible build quality. Their English is good. Great coverage. The painstaking efforts here are impressive.
Thank you very much!

I'm buying more fashion this weekend... Stay tuned 😬
Wow!!!! I have a new respect for this company it was already high.👍🙂🎧
I figured you'd see the same things I saw and the key differences that can be important to many.
Awesome products!
Can i connect Turntable to digital socket and Phonostage to Analogue socket as i need 4 analogue but here is 3 analogue?

I wonder how this would stack up against a Puritan unit?
