Power Cords Snake Oil ??


Having been a long time audiophile living with countless high end compnents I have to wonder about the theory and practicality of high end power cords.

I have yet to hear the difference a power cord makes. Ive owned, synergistic, Shunyata, BMI and cardas. I in no way can detect any sonic signature or change. Give me a pair of interconnects and I imeadiately notice a difference somewhere in the sonic spectrum. Not the PC though. I have accomplished 4 blind tests with my friends. 3 out of the 4 they did not know their cord was replaced. All 4 were using a stock factory supplied cord. Each of the 4 tests were done on different components. Amp, CDP, Preamp & dac.

My electrical backround tells me that provided you supply the component with its required voltage bet 110vac or 220/240vac its happy. Now, change the incoming frequency from 60hz to say 53hz and watch how quickly your soundstage collapses.! This is often the case during the summer months when home air conditioners are in use and the utility company power output is taxed to the max. A really good power conditioner should however take care of the frequency fluctuations. But 110vac is still 110vac regardless of the conductor it passes through as long as its remains 110vac when it reaches the intended circuit. Does your 8k amp or preamp know the difference of the path the voltage took to reach it ? Many an audiophile will use a dedicated 20amp circut for their equipment.That is a good idea as voltage & frequency fluctuations will occur in the home circuit to to other loads on the main breaker panel but again, A power cord simply is the means of transporting the voltage from the wall to the component. IF there is a clean 110vac @ 60hz at the wall socket, no matter what the medium is to go from the socket to the component, it will still be 110vac @60hz.

Could somebody expand on this a bit more. I just dont understand it. ??

Meanwhile, those who claim that an expensive AC mains cable will discernibly or even DRASTICALLY IMPROVE the sound of most hi-fi audio systems have abandoned any attempt to argue the merits or scientific side of their case, instead resorting to personal attacks, changing the subject, making accusations about the alleged behavior of the other side and muddying the entire discourse by focusing on only one aspect of a post and intentionally, repeatedly misinterpreting it.

>>>>>There it is! When the pseudo skeptic’s back is up against the wall he lashes out out with the usual attacks. It’s the other side that’s abandoned rational debate and science, resorting to personal attacks, changing the subject, making baseless accusations, muddying the entire discourse, and misinterpreting the pseudo skeptic’s argument. There is no acknowledgment of or rebuttal of the counter arguments. Just a lotta who shot John. There is no test anyone can devise that can prove cables or power cords all sound about the same. 

Marking your territory with idle comments, again? That’s nice. Pretty soon this thread will be almost as old as you are.

Idle hands are the Devil’s workshop.

I come to these sites for informed opinions and the benefit of others experiences that differ from mine.................sad and interesting how quickly an otherwise reasonable discussion can degrade into a locker room Pss’ing contest............Sometimes it’s not worth the time to sort through the BS to get useful information.

>>>>Yes, I agree. Sometimes it’s not worth the time to sort through the BS to get useful information that agrees with my information. 😛

As an old-time ham station guy and electrical engineer, I started building my own audio systems following WWII, I’ll state, based on many years of personal experience, that power cords do matter; BUT only in those instances where the cord’s gauge isn’t sufficient to carry the load imposed by the device.

>>>>As an younger-time HF Radio, radar and satcom engineer and based on many years of personal experience I think I can be allowed to say that gauge is not the only variable that distinguishes power cords these days for audio. In case anyone was wondering what’s the heck is going on with the prices of power cords these days.  Purity of copper, solid core vs stranded, type of dielectric, quality of connectors, quality of wall outlet, outlet cover, directionality of the wire in the power cord, among other things, play important roles in the sound of power cords.
Nurse! Thorazine! Man down! Looks like a bad case of the peach emoji.
It’s all been said already, but you’re so busy huffing and puffing you probably don’t read it. God gave you two ears and one mouth for a reason. If I were you I wouldn’t wait by the phone for someone to agree with you.

Also, since we all know that Geoff has fake credentials and is a major liar, let’s all agree that he’s a bigger loser than anyone who works at Subway, shall we? I mean at least they can make a decent sandwich. All he can do is come up with BS psuedo-science descriptors for the grifting he attempts to pull off on so-called audiophiles.

Whoa! Let’s keep this civil. I apologize to Subway employees for making that comment. That was wrong of me. However, the fact that you like their subs says a lot.

[note to self: where do all these 🍑🎩 come from?]
I got them old flashback blues. The more things change the more things stay the same. Same old tired arguments from clones of all the pseudo skeptics that went before. Do you really think I never heard all this before? It’s the same movie, different theater. Try to get a sense of humor somewhere. That would be a start.

Spent most of my youth
Out hobo cruising
And all I got for proof
Is rocks in my pockets and dirt in my shoes
So goodbye nonbeliever
Don't you know that I hate to leave here
So long babe, I got the flashback blues

Geoffkait: Oops a Daisy, that was 15 years ago.

Or maybe it’s just more fun to assume he’s reading, while I take apart your non-arguments on the topic and call you out for the trolling you’re doing off-topic.

>>>>>Are you looking in the mirror?

Which is seemingly your hobby and main daily activity:

>>>>>>>I never said it wasn’t. You have your hobby - Pseudo Skeptic. And I have mine. 

Sorry, but I cannot keep up with your "itchy trigger finger" and I have work to do today. Enjoy the trolling in numerous other threads.

>>>>Busy day at Subway?

Hey, what happened to the OP? Is he a...... troll? 🤡 Oops a Daisy, that was 15 years ago. Let’s hope he found salvation with a new Audioquest Hurricane, you know, the one everyone is ranting and raving about, that’s controlled for directionality.
I added this sentence to my previous post just after Mr. Itchy Trigger Finger posted.

There is no test anyone can devise that can prove cables or power cords all sound about the same.

I admit is is easier for me because of my success in business a $25,000 USD wager does not represent a sizeable risk because the loss would not be substantial to my net worth or costs of living so I can use this economic freedom to help reveal and expose those who are using this group for purposes for which the group is not intended and in fact in ways that may be violation of various US laws.

Geoffkait: Uh, you just repeated yourself again. Yup, 🍑🍔🍔


Hey Geoff....you wouldn't happen to sell audio tweaks, would you? I think that if so, it should disqualify you here as it's an obvious conflict of interest when a user asks a forum for objective advice.

>>>>>Experience trumps Asperger’s 🍑🍔🍔
Debate rule no. 1 - When you find yourself losing the argument and you’ve run out of ammo attack the other guy with idiotic stuff you found on the internet. 🍑🍔🍔
I hate to be the one to point out that just because blind tests work in pharma doesn’t mean they work in audio. I got through describing why blind tests are unreliable for audio just last week. You should have been here. But I’ll help you out. The reason why negative results for blind tests don’t mean anything for audio is because too many things can go wrong with the test. Pharma doesn’t have nearly the complexity, i.e., number of variables, that audio does. You’re welcome in advance.
Uh, you just repeated yourself again. Yup, 🍑🍔🍔

Besides, I never said I didn’t have it. That’s probably how I can spot it in others. 😛
Repeating the same dogma over and over, even in the same paragraph, and obsessively blaming placebo for why other people hear power cords, is a sure sign of....you guessed it!

🍑🍔🍔
Do I detect shouting and repeating in speech? You know what that’s a sure sign of?

🍑 🍔 🍔.

Making me hungry.

No. Not necessarily. It means you’re experiencing the placebo effect. Aspergers (or any other ailment/condition) are still possible, but there is no causative or correlative relationship between that and the fact that you are hearing what you want to hear - and - that you wouldn’t hear or be able to point out more than 50% of the time in a true double blind A/B comparison test.

I should clarify my first post, however, to say that "very wrong" is only in cases where the placebo effect has been ruled out.

>>>>It doesn’t make sense that placebo effect can be used as the reason why power cords sound different. Same with the claim that blind tests would prove there are no differences. If either of those claims were true then anyone could automatically win any audio argument by claiming placebo effect or threatening the dreaded blind test. I hereby declare both of those arguments logical fallacies. 
Thank you for the information. But if I can hear the difference between cheap power cords and very expensive ones does that mean I have Asperger’s?
Oh, great, let’s go back to the Stone Age and use aluminum wire for everything. What is this, the Flintstones? Aluminum for transformers, internal wiring, tone arm wire, inductors, interconnects, cartridge wiring. Aluminum for electronics chasses. What’s next, oxygen free high purity aluminum? Six nines long crystal aluminum? Oh, my! 😬 Quick, somebody alert NASA, tell them to ditch those horrible gold fuses in satellites and spacecraft and switch to six nines aluminum ASAP. 🚀

IOW the power cord doesn't 'rectify hundreds of feet of imperfection' because it doesn't have to. It is important for a power cord to be competent though. FWIW, that has little to do with price. The effects of a power cord are often measurable. I've seen them rob an amplifier of about 30% of its output power due to voltage drop across the cord!

What was the cord made of, paper mache? Why would one cord have a 30% drop but another 2%?
Why power cords, wall outlets, wall outlet covers, power cord plugs, contact enhancers on power cord plug contacts make a difference to the sound is one of many audio hobby mysteries that alter and illuminate our times. Obviously, having more stable and cleaner power delivered from the factory would help as would having perfect weather 24/7. And having all the wires in the correct direction. Unfortunately, for most of us, you get what you get.

The units of energy (Joule) are Kg-m x m per second x second, where kg is mass, m is distance, and seconds are unit of time. Thus, the (only) factors that can be involved in changing energy (decreasing or increasing it) are mass, distance and time. Since resonance (cycles per second) is not a term in the expression for energy, energy must be independent from resonance. Anyone agree or disagree?
