Its usually only the sceptre series. For playback since it has a larger sweet spot in the room due to the coaxial design.

The problem is such a graph is not what our brain perceives. Imagine a tiny sound in a busy sound field. That sound in such a graph would not be discernible since the frequencies will be all over the place. There would be small differences which you would write off as being inaudible, yet people hear differences.

ok, its been a year.....

Because the "benefits" of overpriced, boutique mains cables are pure nonsense - and are usually sold to audiophiles with more money than sense, not professional audio engineers.

or people who can hear!

Lucid- narrow-minded closed ear neophites

This is not hate, it's education. A lot of people have limited funds, and want to know what's worthwhile to buy and what is not. Replacement AC power cords are not worthwhile, and it's important to provide accurate advice for people who genuinely want to learn.

Ray R. The current delivery may increase with a larger ground cable if the existing cable is insufficient to meet demand. The entire circuit path needs to meet the demand of the amplifier for best power and thump.

If you make one component stronger within the circuit it makes the whole circuit better.

Scam. Exploitong the naive.

Monoprice NEMA 5-15PHG to IEC 60320 C13 is all you need for any audio gear with detachable power cords.

Well said. I'm very glad to see Ethan Winer comment here. And very sad to see Dave Pensado fall for this. A "power cable optimised for audio" is complete and utter nonsense. As Ethan states, there is NOTHING that the human ear can hear that cannot easily be measured. And there is PLENTY that humans think they hear that is totally imagined (we all know that feeling of moving a fader or knob, liking the result and the realising we grabbed a fader/knob that wasn't assigned to anything). If there is anything to this product (and Dave's instincts were correct right at the beginning, the science is clear, there is zero plausibility here) they should provide incontrovertible proof - share their data and their measurement techniques and give the product to a third party (Ethan perhaps) to repeat the test and replicate the results. There is enough bullshit in the explanations that I doubt it will ever happen.

I agree with your conclusions.

Yep.. If there is a reason for better output ir sound, name it and messure it!

Ethan Winer i agree with you to some extent. But when it comes to a car, regular gas will work just fine, and the car will run great. You won’t notice a difference between pumping regular gas, vs 91 high octane. Butttttt, if the car was a high performance sports car, you will see a noticeable performance difference.

I always find Mr. Winter's perspective interesting. It is one of a religious fundamentalist with deep biases; challenging data being immediately discarded.

Not everyone said he was a fool. In fact, he's just being human. We are prone to cognitive bias.

If that's true, then why isn't anyone questioning his opinions on any other piece of gear? "Cognitive bias" isn't limited to cables, is it?

Now you're making a strawman. Why is that? Here are two reasons: 1. The other pieces of gear are DESIGNED to alter the quality of the sound. So, subjective opinions about sound quality are fair game when talking about processors. 2. With this cable, he is doing a lot more that merely offering an opinion. He is endorsing pseudo-science.

1. Um, these cables are also designed to alter (i.e. improve) the sound quality. 2. It is also an opinion that this is just pseudo-science. No real scientist would dismiss a reported phenomenon out of hand -- it would be studied and experimented with before making any judgments. I am not a scientist, but I've heard with my own ears how cables affect sound. And not in a subtle way, either. I suspect most of the nay-sayers here have never bothered to put cables like this to the test.

No, they only CLAIM to improve the sound. They're cables, not equalisers. It's all about evidence. For example no one will argue that an eq doesn't change the sound, that's what it's designed for, it's well established because there is so much evidence- equalisers have been around for a long time, and their function is easy to understand. Thing is, the guy has fudged the evidence for the cables. Pensado being a good mixer has nothing to do with his ability to test a cable. He didn't do a blind AB. Humans are easily biased.

yes, really. 30 day trial....have your mind/ears prepared for a delicious surprise.

Michael D. Griffin is welcome to send me one. I'll do an A.S.S. (Audio Skeptics Society) review on them.

I don't fault anyone for being skeptical. I was highly skeptical, even though I met the owner at AEC NYC. He was hardly any sort of snake. But again, it's hard to believe this stuff until you have a firm understanding of the physics and can A/B it for yourself. An untrained ear is going to have trouble distinguishing. I mean, what's my word against millions of Autotune zombies? Good taste can only take a person so far.

I was already aware of the major impact it had on bass and clarity in guitar cabinets. I'd heard its affect on beautiful Fender and other tube cabinets with great guitars. That alone had sold me. The guitars sounded twice as good. What completely surprised me is that it had a discernible impact on my Apollo interface. I'd assumed that the draw of the headphones would be so small as to have no influence on the voltage output and its dependency on the power supply. Boy was I wrong. It skewed the master I was in the middle of working on. Because it emphasized the low end more succinctly, the master lost some of its upper mid-range emphasis. In essence, my mastering decisions compensated for the differences in the power draw. Granted, the default cable was probably ever-so-slightly noisier, but that's not necessarily a bad thing when the effect is so subtle (I've become a noise aficionado of late). Again, the point is that I was surprised the cable had any impact at all. I already know it's a superior impact due to the clear advantage on guitar + cabinet A/B comparison. But in the case of the interface, I felt I was able to compensate for the differences. I might have felt more strongly about it if I were more reliant on monitors and the bigger power draw required to push in contrast with my high-end headphones. I generally prefer the headphones, because they are perfectly flat from 20Hz to 20kHz, and I don't have to deal with room resonances. I use them in combination with a SubPac. It's an amazing monitoring system, really.

I should add that I'm generally quite critical of hi-fi misconceptions. 192K versus 44K is a great example. I'm actually very outspoken about audio bullshit. thenoisegroup.com/audio-tech-blog/44-1khz-vs-192khz-david-and-goliath/

If you have a firm understanding of the physics, you believe it even less.

lol

Indeed, Blood Lord. I never trust sound samples from the manufacturers.

kzfaq.info/get/bejne/kN-Hp5acprSlY4U.html Here's the proof :D

@@bubbelchampagne I think you're in the wrong thread, bud. This is power related, not speaker wire related.

You have a point there. However, what's still relevant is that I still haven't seen any evidence of that working. If such products really worked well, wouldn't manufacturers proudly show this with concrete A/B examples? :)

​@@bubbelchampagne ​If you had read my original 2016 post, you would've seen that I am also sceptical. However, since power is different to signal, I'm willing to listen either way.

1. Because every power supply either has a very large filter in it (linear PSU) or completely re-constructs the signal (SMPSU). 2. Because 1m of "fancy" cable can't make a difference to the kilometre of ordinary cable between the pole on the street, running through the walls of the building to the mains socket. 3. A listening test is no good. The only thing that might (and it's a very slim chance) make a difference is RFI in the room. But that's not accounted for here. 4. If there is an RFI problem, it should be dealt with at source. Not with over-priced cable. 5. Last but not least- a listening test is useless because cognitive bias will occur. It has to be a blind or double blind ABX test. But that's far too much trouble for Pensado to eliminate all of the variables. Floyd Toole shows how we do those. He did them at Harman: kzfaq.info/get/bejne/sNigiKemutrcgIE.html&ab_channel=CIRMMT

because the power cord is the filter....your example changes nothing....you get a 30 day trial... try it...or shut up.

so, using a cheap chinese power cord is bad, soldering the power transformer direct to the mains is bad, but using an specific power cord will magically make your sound better. okaaayyyyy

"oh ye..."

What Dave says is the cable acts as a bottleneck, so I imagine the cable stores and distributes the power more efficiently

Unless you're welding or running a PA, a mains cable will most definitely NOT be any sort of bottleneck. Cursed snake oil peddlers, taking advantage of technically non-savvy people, it's pathetic and disgraceful...

***** But just because it meets / far exceeds industry-set standards doesn't necessarily mean it (also) *sounds* good... :P (I *am* of course only joking...)

Michael...wall power is what the cable is affecting....as a filter. try it...30 day trial.

It probably won't make any difference changing the TYPE of cable running in your wall to the mains distribution. But installing a spur dedicated to your hifi alone definitely does.

Still just as BS as it was back then, though.

If true, this goes against KZfaq's terms of service.

RealHomeRecording.com If what's true?

That the video is a re-post. You're not allowed to re-upload old videos.

Unless you delete the old one first. In that case, Mr. Pensado is in the clear.

Highlighting flaws in your equipment? As if the cable knows the difference being in the room vs in the wall. Bottleneck? How long should you run cables before you plug them into a common plug strip? Better change as much cable as you can. Looks like your equipment needs it. I would have thought there would be less improvement on well designed equipment not more. So the cable only helps during the cap charging portion of the cycle? So for part of the 60Hz you listen to the cable and the rest to the caps. I use synchronously rectified switch mode active power factor corrected supplies with plenty of buffering caps on my power amps and constant current shunt regulated supplies on line level stages. The mains have have then virtually no correlation to what I hear. Maybe time to ditch the old fashioned transformer/capacitor power supplies which causes interference amongst equipment due to short current bursts. Having fully differential source and amp topplogy helps a lot. O now the cable is shielded thought that was an early question. You dont have conplete control over the power interface end to end like you would have on interconnects and speaker cables.

I agree

there is no question, better cables make a bigger difference with better equipment.

This comment alone debunks this whole power cable market. Standard in-wall power cabling is 14 gauge. Anything thicker than that is a waste of time. The system is only as good as the weakest link.

May or may not be true. Maybe they have some electronics in the cable that make it store energy and make it respond faster or whatever. In that case everything behind the wall just supplies power and the power cable distributes it more efficiently. I would have no reason to believe Dave is actually bullshitting us.

Since there has (obviously) not been any double-blind testing going on, *IF* there's any difference it's down to confirmation bias, plain and simple. Store energy in the cable, hmm? How, pray tell, does one store AC, i wonder?

Ethan Winer debunked the power chord thing years ago.

Chad Johnson I'm pretty sure i linked Mr. Winer's two AES videos somewhere in my comments on the episode this was taken from

Sadly. they sold out a couple years ago. But I don't think it was Dave who initiated the sellout.

Extensive tests? You mean, double-blind ABX tests?

I wish.

Yeah, i'm from russia and i work for them too, lol! It works, guys, even with your two meters from power outlet! Dunno about type of the cables, but with or without power cord shielding - yes. it works. i'm telling you this as a user, who did the same tests.

Where can we find evidence that power conditioners improve sound?

I thought his safe word was the number of "hem" per minute.

no, add this cable, it will filter the crap coming from your wall.

Most concerts sound crap. No wonder cheap cables are part of the problem.

Honestly, I think he gets money from the plugins he advertises. Same for hardware.

you are obviously a poor judge of people. few are as genuine as Dave.

he did, he has i did, i have you havent.....try it....or sit down.

do your own...30 day trial....but be prepared to own the cable....and eat your words.

you couldnt be more wrong. try it.

Even "mains conditioners" is mostly nonsense, unless you live in a third world country. Any problems with "power" ware easily heard as clicks and pops and hum etc. The notion that "subtle changes in clarity" are affected by AC power is either fraud or incompetence. If they know they're lying they're criminals. If they don't know they're lying they're imbeciles. Take your pick. :->)

Reactionary comments like this make me even more curious to investigate, just so you know. And I'm sure Dave shed a tear when you un-subbed.

that you are arguing is ridiculous.....try it.
