FWIW, I've tried it. That's why I don't use the generic cord.

We are creating more and more sample video's in which you can experience the differences.

We can do that.

@@TheAlphaAudio it will show that there is some difference at all ! It must not be osciloscope, it can be easily done with recording sound with cable A and cable B and look for differencies. But there is no difference, so measurement is not done by cable impostors ..

Some Folks will never ever understand that Engineering is what counts. Not how much money you spend. This is flat out B.S!

Phd in electrical engineering still the knowledge less than an undergrad in the same domain. Transistors are non linear, super sensitive devices with super complex power consumption profiles. Anything can matter.

I suggest you get your tuition back. Unfortunately you can't recoup the wasted time exhausted. Perhaps its not too late to get a degree in psychology because according to you hundreds of thousands of Audiophiles are experiencing delusions.

E Barbie - 1st Paragraph: but there can be.

And liar too

He's telling how a cap charges on start-up. but they hold a charge and supply the components with those peaks. Because of very large caps, so the draw is not linear across the power supply.

Yes Snake Oil.

Why do you care? Hifi cables are for people interested in hifi, not for engineers. We don't care about measurements or technical explanations. We are interested in what we hear.

@@StefanoCipo87 Well I'm talking about power cords, tho other cables are of some question. When I heard a null test between a give away audio cable and an expensive cable I started to examine some of my beliefs. What I care about is expensive stuff being mis-represented to people that maybe don't have the money to spend on something that only fools you into thinking it sounds better when it could be spent on something that really makes a difference. What we think we hear is not always accurate so we can use measurements and technical explanations to see if it's real or placebo. And audiophiles are all hung up on measurements, Except when they show up placebo improvements.

@@bradt.3555 i don’t have experience with very expensive power cables, but have tried several good cables (100€ per meter plus connectors , diy), and on my modest (but quite resolute) 10-20k€ system they do make a very noticeable difference, much more than interconnects and speaker cables. In fact, in my experience everything related to power always made a very noticeable difference, including connectors, inlets, power strips, filters, fuses. Your experience might be different, I don’t question this, but I will not question my experience which is very clear. i don’t need scientists to tell me whether my perceptions are true or not, nor in audio nor in other fields. I think more expensive cable could sound better, otherwise they couldn’t have a market (of course there could be bad products that people like to buy just because are very expensive). I don’t like and don’t believe the pseudo science to explain why they work, I would appreciate more they told the truth, they designed cables by trial and error, and by experience, and found some that sound really good.

@@StefanoCipo87 Well i'll try to keep it short as you seem to be in the camp of denying expectation bias. If we expect something to sound different it likely will even if it doesn't. That's where science comes in. There is just nothing a 6 foot power cord can do that will change the output of the devices power supply. There has to be a difference in the signal going to the speakers to have a diff. in sound this is fact, it can be measured. The market is there because manufacturers understand "placebo effect" and use it quite effectively.

@@bradt.3555 I know what expectation bias is, I'm a physician and researcher. However I cannot deny my perceptions, which are not subtle and are repeatable. Yes I don't deny I'm victim of bias sometimes, that can happen when we expect a difference to exist. However in my experience the differences in sound when it's bias are subtle, I have a feeling that something has changed but I'm not sure. Going back and forth with the change (cable or other) doesn't clear things up. Ultimately I realize there's no difference. Other times differences are not subtle, are so obvious I cannot question their existence, same as anybody would not question actually seeing something in front of their eyes. In these cases changes are 100% reversible going back and forth. Expectation bias has not worked the first time I tried a good calbe (diy yarbo OCC cable) on my system. I really hoped there to be an improvement in sound compared to stock power cord, but there wasn't. There was the "maybe I feel something different, better bass" thing, but it didn't confirm and I ended up not using the cable. Months later, after having upgraded the speakers I tried the cable again on my preamp, and it did make a very noticeable difference. I then tried different cables and found how important they are. Expectation bias also didn't work when I bought the iFi AC purifier, sold it because it made no difference. But a different, better AC filter I tried made a big improvement, and I still use it. Expectation bias didn't work when adding a supertweeter to my system, and I really believed it would have made a difference, since the manufacturer of my speakers told me so. I could go on and on, the point is I'm sure about my perceptions and cannot question them, to me that would be crazy. I believe you didn't experience differences in power cables, it can be due to a number of reasons, including not listening to a system/power cable combination where a difference actually is noticeable, your hearing not being capable of telling the difference, you having a reversed expectation bias (since there is no scientific explanation for the phenomenon, it cant' exist), or maybe you hear a difference but are confident it is actually a bias and not a real perception. I couldn't know what is the case. As for measurements, that is not my field, but I can think it could be that not everything that makes the sound we hear what it is is actually measurable with current equipment. Or we don't measure the right things. To me to show two sweep responses that overlap only means that probably if I listen to sweep responses on that system they will sound the same, but who listens to sweep responses on their hifi systems? Music is a different thing from sweeps and pink noise. I can think of many other reasons why measurements could not reveal a difference but I don't have technical knowledge so I'll keep them for myself

Don't be a moron. Use the provided power cables. You'll be throwing 500 to 1000$ down the drain... Better use them to upgrade your system with better components, like a second subwoofer . Now, from an engineering perspective, and I happen to have a PhD degree in electrical engineering, with plenty of experience designing and building switching power supplies for an Israeli company called Advice, there could be no audible difference between an 8$ and 6000$ power cables. The best results in terms of EMI noise immunity can be achieved by a cheap DIY power cable with the two main wires (live and neutral) twisted together, and the ground wire wrapped around them and acting as a shield. Such a cable will cost you 10$ to make. Exotic copper wires don't make any difference, the same goes for LC-based EMI filers, which are already included in the audio components. Moreover, the sound quality is not affected by additive high-frequency EMI noise. Audio components need DC power to work. Assuming its a good high-quality component, then all necessary efforts were already taken by the manufacturer to insure clean dc power supply, regardless of the ac mains conditions... At the company, I worked for, we had one product which was a true sine online UPS. We did many blind A/B tests using a high-quality audio system and nobody could tell the difference. Exotic power cables are the biggest selling snake oil products... Audiofools love them and are obsessed with them... It's a great business... any idiot who got scammed and paid 1000$ per one meter of power cable will do anything to convince himself that he can hear the difference.... Just use the free power cable and you're good...

@@ebarbie5016 You are a electrical engineering PhD named Barbie eh? Ok Barb, is it ok to pay 70 bucks for a well built shielded power cable or should I stay with the 10 dollar sht? (No 2000 dollar sht...just 70 bucks vs 10 bucks...) what say you Barb?

@@wa2368 High tech airplanes use non-shielded cables, hundreds of miles of it. what do you think?

McIntosh amps come with a Shunyata power cable in the box😉

@@davroster so from the fact that ii may wrote incorrectly something discredits what im saying….ok

dragocat1 - they also have a venom series of cables because of their snakes

It's like a tube around the cable or like a two dimension capacitor. You better not put your fingers on it. It gives back power spikes when the cable is "loosing his breath". It's only a metallic tube, but it's patented, don't try to copy that !

Always remember: "pAtEnTS ProVe thAt It wOrkS!" as implied by every snake oil salesman ever. I read part of the patent, it's a weirdly shaped capacitor with a high value resistor across the plates at the end of it. You can find it here: patents.google.com/patent/US10031536B2/en

because there is no difference :-D

That's right!

Power cables most definitely matter. On the power amp (strangly) it has less influence as connecting to a Dac. But your system has to be in balance and good... then most people should hear a difference. With cables u can tweak it a bit more to your liking (when the rest is good). You cant make a crappy system great by cables. But a good balanced one you can make sound better or worse.

Replying to ( E ). perhaps I should have spent a lot more on the cable and I agree you can't make a silk purse out of a pigs ear. The system I have is a Quad artera pre plus CD player matched to the matching Quad power amp.The XLR interconnect - Tellurium Q Black Diamond £1,200. - the speaker cables inc:- jumper leads Audio Quest Rocket 88 to ATC scm 40s standing on Townshend podiums .Mains block is the Swedish company Supra 6 gang. So perhaps an upgrade to the mains filtration ? ⚡

@@andrewaajohnson7584 I have red on a forum a few days ago that upgrading from a Supra (cant remember which one but could be the 6 and to which one) made a significant change. The most important thing of course is the phase of the power cables in the mains (and the mains). They must be all correct. I cant measure so use my ears on what sounds best for all components. Yesterday my system sounded wrong, no strong basic and out of phase. Turned out my power amp was plugged in wrong. (We have EU connectors, maybe US is one way only). After founding which was plugged out of phase everything sounded correct again. Oh, and more expensive doesnt always mean better (often it does). I even heard a 5k system on a show that was perfectly balanced. Great! Before that we heard a 200k system that sounded not in balance, too bright and so on... And another 80k system with a expensive record player sounded amazing....!!

Wrong

Guessing you haven't tried any or your rocking a dismal av amp

That's because Audioholics, who is an engineer and actually tests, flat out say's POWER CORDS MAKE NO DIFFERENCE in what comes out of the device!

@@bradt.3555 if you have ever tried a different power cord (any one that has a lower impedance than a stock item) then you would know they do make a difference to the sound. If this is value for money is another matter. Just because you measure something does not necessarily make the measurement correlate to the effect or outcome you are trying to understand.

​@@richardpalmer9616 Yes I have tried different power cords. To know if there's an impedance diff. in a 6 foot piece of wire, you gotta measure it, so measurements DO matter. I've never seen anybody list the impedance of a cord, or DC resistance. And then if there were a diff. which in a 6 foot cord would be virtually UN-measurable. It would have to be so small a wire as to affect the voltage (based on current draw). Check the wattage draw of say your power amp, not output, but max power consumption, then divide by your voltage, see what your amp draws. That would be max peaks at max volume. Or measure what your amp actually draws then see how tiny the wire would have to be to actually get a voltage drop. Then you have the filter caps in the power supply which will handle instantanious peaks because of their large value. The supply side of the power supply won't even see the ups and downs of a musical program. Remember there's not audio signal here it's raw power for the power supply. What comes out of the power supply is what's used to turn into audio signal. Unless a cord is defective or WAY to small for the current needs of the device, a power cord cannot change the sound. Listening to people describe how a cord does anything is like listening to Jordi LaForge explain how the dilithium chamber works. I have enough years of electrical exp. that I can make up tecno-babble that sounds totally believable but is meaninless. Sound is produced from an electrical signal making a speaker move. Same signal- same sound, it can be measured, has been and the effects of a power cord, by electrical engineers, sorry no go. I apologize for the length, it's hard to explain without just saying no they don't.

@@bradt.3555 hey thanks for the reply, and I am also an engineer in past life, I used to be an academic (senior lecturer) so for sure I understand the value of measurement and the scientific method. I can however hear differences in mains power cables, it would be slightly ludicrous to imagine the entire market for such a product was reminiscent of the emperors clothes. If you have a sensibly revealing system and you make the effort to listen I am sure the majority of people could hear such changes. I also recognise scientific mumbo jumbo boiled down to and icon and an acronym doesn't help sell any authenticity to me and many others. Cables even when they should logically not, do make a difference. Better knowledge and science I believe could explain this in the future - but not know it seems.

Worst presenter in the world 😢

E Barbie You have employed scientism into your thought, i.e., if you can’t measure it it, you can’t know it. I say that your instrumentation needs further development. I can hear differences in cabling whether power, interconnect, or speaker. Of course if you have cheap components you will never hear what component changes can do.

Hmmm. I figured a PhD would know how to spell pinata.

@@Mike82ARP There are three types of PhDs online. The ones that are just lying, they really don't have a degree, the ones who have a degree but it's in philosophy and then you have the ones who own Bose. It never occurs to these morons that these companies are founded by engineers and or have engineers employed working for them. Many of them openly admit they don't understand why cables sound different. So, we either have incompetent engineering schools or maybe there is something to this cabling controversy. P.S. I guess they don't teach PhDs to engage a spell check program either or how to use punctuation.

@@carlosoliveira-rc2xt You don't understand why a mains cable can't change anything so you resort to ad hom.

@@nickvankreij1626 Changing a power cable doesn't do anything at all on any hifi system, which you would know for yourself if you understood electronics. It's one of those instances where knowledge helps you to weed out the nonsense (and there's a heck of a lot in hifi).
