I perfectly understand what they have talking about. And it is true. Power cords shielding is a must. There is another interesting thing like power filters for each audio device, that can helps you even better. Shocking better. Even a deaf human simply hear the difference on blind test. I tell you this, because i have it at my home studio. It works absolutely amazing. Better stereo imaging, and clarity. Better bass and overall impulse response only with power filters on the prepared studio power grid. Many peope saying about snake oil, because they didn't make blind tests with shielded and filtered power cords. It is stunning difference, i'm not advertise, just test it. Do the blind test, all of you! Cheers! I'm not hi-end lover, but this is works. Yes, maybe it is too expensive, but do it yourself. read, learn and do it. simple as that. This will costs you much less than buying such cords from a boutique. Again, love your channel, keep up the good work! :) Cheers from Russia! :)
Nah if you don't mind I'll wait until Steven Slate brings the 'Slate IEC Power Cord Plugin Suite'. 🙄
Why all the haters? Try it, if you like it, buy it. If you don't, keep moving!
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.
I was VERY SKEPTICAL too-UNTIL I TRIED ONE OF MICHAEL'S ESP MUSIC CORDS with my bass amps!!!! I am now a UNSKEPTIC!!! Thank you for a great interview with a very intelligent engineer!
I could hear the difference coming out of my iPhone on CZcams. Amazing.
It's not snake oil. I've tested this exact cable on guitar and bass through cabinets as well as my Apollo interface. It makes an audible difference, even for playback through hi-fi earphones (8Hz to 32kHz in my case). I decided against buying it for the interface, because it caused enough improvement to throw off the masters I was working on. I was shocked that it made any difference at all. I'm a mastering engineer. The difference is obvious to me. I will have to buy one of these the next time I play bass on stage. There's just no ignoring the result once you've heard it. There are plenty of videos of bass and guitar comparisons that are just as obvious. Not all people seem to be able to hear it, but to me is was as obvious as a sledgehammer in the face. It's not imaginary. The power draw performance directly contributes to the accuracy of the transient reproduction. Keep in mind that I have shitty wiring in my old home. It really doesn't matter what the source is; the cable corrects it.
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.
I'm not gonna say anything negative, because this is over my head. And I do understand gear and mixing. I do know that I can occasionally hear interference in my monitors (Yamaha HS7s) while mixing. I know it's related to my system (switching to SSD drives removed a lot of it). I don't hear the same "hums and chirps" once it's exported out as a WAV or MP3 and playing on another set of speakers. But I can't help but wonder if that interference comes into play when recording direct into my audio interface with guitar and bass, or vocals from a microphone. If there's a problem at the source level that's being recorded, I have no doubt that will influence the mix. I know this video is going to get a lot of hate, but sound (and especially power/electricity) is some pretty complex stuff. I wouldn't write this off as snake oil just yet.
Im not going to be a hater, and play like i'm a expert like some of you guys on here. i'm just going to buy one and see if i can hear the difference. i know clean power is a factor if it wasn't Mogami and Furman would be a Factor.
ok, its been a year.....
It's a funny thing -- gearheads will talk about how various pieces of hardware or software sound, describing the sonics in detail and judging one as clearly better-sounding than another, even if the differences are very subtle, and no one bats an eye. But if anyone, even a seasoned pro like Dave Pensado, has a reaction like this to a CABLE, he's immediately declared corrupt, stupid, or just a fool. Why is that? Cables can and do make a difference to the sound of an audio system. Until you try it for yourself, please don't dismiss the findings of those who have.
And if you really do believe that anyone who hears differences among different cables is being fooled, that their ears are faulty, that what they're hearing isn't real, then please explain how Dave and other "fools" can produce good-sounding music day after day after day. I mean, if they can "hear" things that aren't really there, then anything they mix might sound bad. I don't think Dave has this problem.
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.

I understand all of the negative views, I had them until I plugged in the power cables and heard a difference, a big difference. I was the biggest skeptic on power cords until I heard the difference. I had no problem purchasing these for my tube gear and it was worth it for me. I do understand the other side of the argument, I was there for years, but now I am a believer.
Nice to see the warmth and respect between these guys.
I'm sceptic...I mean the power supplies in the machines are here to store energy with their smoothing capacitors and stuff. If there is a difference, it would vary from gear to gear depending on the power supply design. And what's with that phase thing? An OPamp for example won't distort phase if the circuit is designed properly, regardless of the power chord, there is no phase to fix in what we are hearing from our well designed machines, exept if there are audio transformers but arent we supposed to like what they do (still has nothing to do with power cable). The only thing I could believe here was the fact that shielding the cable is better so you won't get the 60HZ in the studio's magnetic field (but then all the walls should be shielded as well)
awesome interview
For all those saying that this isn't true and it's "snake oil" - prove it. We, here, that want to know about these kinds of things are interested in results. So, inform us. Don't just drop an opinion, stated as fact, and expect us all to take what you're saying for granted. Give us something to read, hear, see, etc. that is directly related to this product. Otherwise, if you're not willing to do that, you're not helping anyone.
I don't blindly accept what Dave and co. are saying in this video, either!
czcams.com/video/ZyWt3kANA3Q/video.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:
czcams.com/video/zrpUDuUtxPM/video.html&ab_channel=CIRMMT
Any change that is audible is measurable. It's trivial to prove that a replacement power cord improves fidelity by measuring the output of the connected audio device with both power cords. But the people who sell these "placebo based" products never do. Or of they do the data is either fraudulent or incompetent. Shame on Dave for falling for one of the oldest scams in audio. More information, including a detailed explanation of what affects audio fidelity and what does not, is in two AES workshop videos you'll find on my own CZcams channel.
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.
If there was a large audible difference, couldn't someone set up a decent measurement mic and record a frequency response graph from the speakers and compare cable A to B? You could see the overlaid graphs and see if there was a difference in the freq curve between the two recordings. Is there any videos of someone doing this?
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.
can't believe it... is it the 1st of april in US today?
It doesn't work. The colour of your t-shirt has a bigger difference. This is tragic.
why so many dislikes?
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!

Sangji Bello Ariza ?
Lucid- narrow-minded closed ear neophites
ok.. waiting audio file for comparative test. many test for plughin and gear, no test audio for cable ? ....
Some of the responses concerning power cords are ridiculous. Like suggesting computer analysis of the frequency range, and sonic characteristics, ect. of the cord to prove it sounds better, or makes a difference compared to a stock black molded power cord. That is like, for example, analyzing skin samples, bone density samples, checking body fat ratios, collagen samples, ect. on Ellie Mae, in order to prove she is more attractive than Granny. Just install the power cord in the system, and listen. If someone has to be shown scientific evidence to be able to tell a difference in sound, they might need to find a different hobby.
looooooooooooooooooooooooooooooooool
anybody in car audio already knows this. The bigger and better (lower gage) the ground wire is the more power gets to the amp and makes it louder and thump harder.
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.
Simple question, if wiring in wall installation is good enough, and cables comming from wall outlet are bottleneck, why not just use same type of installation cables used in the wall all the way to the gear, and keep em as short as possible?
Oh, and the fact that dislikes outway likes, says a shitload about this...
I think what he is saying is it is worth a try. If it makes a difference and you can afford it then why not. A nice stereo compressor is like 3000.00 If I could hear a difference 137.50 would so be worth it for me. The sales tax was more. I heard a huge difference when I added balanced power. Yes if your whole rig is a beginners than no its not for you, there are better choices for you to invest in, If you have a room like Pensado then it could be worth it.
when it comes to a car, regular gas will work just fine, and the car will run great. You will see no 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.
Why is it not written which cable it is?
First time seeing the presonus speakers in a studio I respect time to give them another look
Its usually only the sceptre series. For playback since it has a larger sweet spot in the room due to the coaxial design.
Power supply really does make a difference in recording engineering, but not for sound? More for the protection and adequate power for your components. Sound?! REally?!
yes, really. 30 day trial....have your mind/ears prepared for a delicious surprise.
All I'm thinking of is all the award winning global smash hits Dave mixed without these cables.
$200 a cable, $600 for the distributor. Very Pricey!
Scam. Exploitong the naive.
Monoprice NEMA 5-15PHG to IEC 60320 C13 is all you need for any audio gear with detachable power cords.
ESP makes great products based on solid engineering principles and concepts. Just buy one and try it out, if you don't like it return it. Simple!
I don't trust his mustache
lol
What is the cable called and what price
no sound test.....
Indeed, Blood Lord. I never trust sound samples from the manufacturers.
How are you hearing anything with those tiny speakers in the back,
i dont give 2 hoots about measurements. i care about what i hear.
ac cables affect sound.
ac conditioners affect sound.
regenerators affect sound.
been there, done that.
i promise not to tell you what you can hear.....dont tell me what i cant hear.
A happy electron is a better sounding electron.
lol power cables
dafuq m8, how can u say this ll up a kids game? if anything it ll make it worse because you dont hear what it would sound like on a normal system set up without 600$ cables, besides it would only make sense in a recording setting, how can you even compare it to investing in a daw, i mean i understand that just as protools it is expensive & a fuckload of shit not worth the investment^^
I agree
But if you couldn't hear the difference before you got the cables, what difference will it make for the people who listen to the music you've mixed? The only way this would make your music sound good to anyone outside of your studio is if they listened on a system that was of equal quality or better. What demographic is that? haha
$600 for a 6 way power distributor and $150 for a 2 meter cable? Yeah, sure.
god this is embarrassing. dave pensado of all people should know better, unless hes just in it for a pay cheque which is just as disappointing
Dave needs to do a blind A/B. If he can tell the difference consistently, we have something of substance to talk about. Short of that, this is just an infomercial.
Seems legit.
Oh damn, someone sold out.
Sadly. they sold out a couple years ago. But I don't think it was Dave who initiated the sellout.
Oh... god... what the heck is this? :/
Snake oil claims and "quantum freeze aligned atom power cables" in a professional mixing channel?
Please don't.
Yap yap yap. This absolutely smacks of experimenter bias / confirmation bias.
Stay skeptical.
I'm sorry, but the wiring in your walls is what it is. Somewhere between 14-10 ga. It might run 10 feet, it might run 100 feet, or whatever before it gets to the socket in your wall. After that, it's just 5 or 6 feet to your stereo, maybe more, maybe less.
If anything can be greatly changed and improved in that few feet of cable before your transformers, wouldn't you think that that technology would already be applied inside amps somewhere?
This crap reminds me of a guy I used to know who changed the fuse in the back of his guitar amp every month because he swore it made it sound better.
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.
why don't hardwire the amp to the wall socket?? Just put the amp close to the wall, dismantle the wall plug and solder the cables from the wall into the input of the power transformer. Eliminate the power cord!
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..."
7:48 why does wall power not matter?
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.
Why so many unlikes? This is an interesting topic and good video.
Because it is bullshit :D

If not, Ethan points out all flaws in that video, check it: czcams.com/video/6rB2W0umdq0/video.html
Hospital-grade power cable -NEMA 5-15PHG to IEC 60320 C13 is all you need for any home audio gear or pro audio gear.
I thought this was snake oil until I ran extensive tests myself with various power cables I already owned. I wonder what the cost of these cables are. I suspect they are too pricey for my studio.
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.
This is a repost from like a year ago.
Still just as BS as it was back then, though.
If true, this goes against CZcams'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.
Please post your measured results here, ie power cords. A link will do.
This video smells funny.
If this dude can walk into Mark Waldrep's studio and change Mark's mind I would take it seriously, until then - meh.
Pure salesmanship. Lost some respect for Mr. Pensado here..
I did comment the first upload. I really do find it surprising that they even reupload this episode...
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.
What about the power lines in your wall not being as good as these power chords? This is snake oil.
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
All y'all Skeptics talk and talk and talk....I live in Jamaica and bought my fifth cable thus far and when I say that these cables changed my lifer mean every word...this is the video that also did it for me....thanks again Michael D. Griffin....awesome cables and overall products.
Watched in utterly amazed disbelief, horrified. Waiting for Dave to say the safe-word indicating his statements are made under duress. I can only assume there's a guy with a gun off camera...
Aiding and abetting these con artists once is a mistake, doing it twice amounts to complicity.
Quoting Pink Floyd - The Wall Socket;
"Dave.., Dave.., what has become of you? Is there anybody else out there who feels the way I do..?"
For real science please read here; sound.whsites.net/cables-p4.htm#power
I thought his safe word was the number of "hem" per minute.
At the price of these cables and distributers, it would make more sense just to upgrade my lower end gear, rather than just polishing a turd.
there is no question, better cables make a bigger difference with better equipment.
Just Buy a Technical Pro or Livewire power conditioner and dont buy that expensive cable.
Where can we find evidence that power conditioners improve sound?
ANY changes to a Audio or electrical signal in the TRANSMISSION LINES will effect the attached electronics performance,PHYSICS people!!!!!
Placebo is a hella of a drug!
dave really be selling anything these days lol. garbage.
So this is a 20 minute commercial for overpriced power cables, with no audible tests whatsoever? Lemme just put this on the pile with Monster Cable and mixing in Dubly.
you sound and lppk like a liar
Why are all of you so angry? Measure this, measure that. I'm so glad I don't live life like you angry people.
i dont think dave should of made a video on this. though i believe it to be true, the margin of improvement in the "game of inches" is so small that spending $600-1k on that inch wont help people mix better, and will only provoke the emotional "snake oil" responses
Pensado is a Great interviewer but simply ignorant of the means by which to test fidelity and the physics behind audio reproduction and circuit design. It is this type of "intuitive" sense of "knowing" how a power supply works that allows con-men to find their mark.
dave has officially lost the plot
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.
Unsubbed, pile of garbage sponsored video. Mains conditioners yes, thicker power cables with shielding pffffffffffft coff.
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.
0:17 "I want you to 'play along' and witness what's going on." Hmm... What is going on is - Herb has sold Dave Pensado out. Instead of providing informative audio technology information, he does paid advertorials for overpriced snake oil. RIP Pensado's Place and RIP Dave Pensado's reputation. I am not going to 'play along' any longer.
More like into the liar... amirite?
Dave has done him self a disservice. I am not saying he doesn't believe he is hearing a difference but he should have conducted an A/B test with a third party before he put his reputation on the line. If there really is a 'night and day' difference people would be able to spot the difference with 100% accuracy under the blind A/B test conditions, and with this proof they would sell huge amount of cables.
he did, he has
i did, i have
you havent.....try it....or sit down.
That's an entertaining advertisement.
Oh, no......I have to change my power lines in my wall...
no, add this cable, it will filter the crap coming from your wall.
They seem to not know how a good power supply is made, extremely funny.
A guy who builds cables needs a body-guard??
Dave is great but damn is he bad at speaking.
A-B Comparison? Otherwise I don't believe a word.
do your own...30 day trial....but be prepared to own the cable....and eat your words.
I smell bullshit.
I produce and promote concerts. The system has no power conditioning. At the right venue (acoustics) the system comes extremely close to CD quality.
At the volumes we run any hum or hiss is totally audible. Top international artistes tour with great sound engineers, they won’t be too pleased if the sound is ‘dirty’.
Bearing in mind we take venue 3 phase or from gensets (sometimes the cabling and db boxes leave a lot to be desired), yet sound is clean, clear with great dynamics.
Most concerts sound crap. No wonder cheap cables are part of the problem.
This is BS without measurements to prove there is a difference.
100% rubbish.
This video is confusing.. not impressed...
Sounds like bullshit to me.
Shielded power cord: Having a couple of feet of shielded power cord will have zero effect in comparison to the miles of unshielded copper cable from the power company's step-down transformer to your wall outlet.
The claim that the shield on the power cord protects signal cables nearby from the induced radiation: This is rubbish, because shields don't affect magnetically induced radiation unless they are ferric (and I seriously doubt these are ferric). And have nearly zero effect on radiated interference at low impedance (which power cords are) at 50 or 60 Hz.
Power cable is spiral-wrapped like a CAT-5 cable: Supposedly to reduce pickup of interference through common-mode rejection - but this is again negated by the miles of untwisted cable from power company's transformer to your wall outlet.
He is talking about psycho-acoustic effects, not physical/measurable effects - which are more likely to be caused by placebo effect in this case as a result of failing to conduct a proper blind A/B test.
Where's the technical data? Or the mechanical design discussion explaining how it works? Or the signal plots showing hard evidence? Non-existent.
What happened to Pensado's Place? This is pure garbage.
