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. ??

For anyone casually stumbling onto this particular thread such as I did the other day, or the OP following up on his long-ago request for advice, it must be very interesting to note that "sides" or "camps" have been formed and that the members of one "camp" engage in one type of argument while the other side has chosen a different approach.

Those of us who claim that there is no scientific merit to manufacturer statements that - across the board - a "high end" or "higher quality beyond AWG and shielding" power AC cable will make an audible, discernible difference, nay, IMPROVEMENT in the sound of every high-end system of a certain caliber are attempting to focus on real-world physics, engineering, or solutions that even involve some form of teaming up with the other "side" to prove once and for all who’s right and who’s wrong. That kind of solution requires some kind of capital outlay by either a manufacturer or participants in a side-wager to the type of study that would be required to end this debate, but why not brainstorm about it here without getting personal or misrepresenting what the other "side" says?

On the Mfg. side, I offer up an example such as Shunyata’s (comments disabled) video whereby they purport to present a demonstration of their superior power cable by using a peak current meter on an AC outlet and then on their cable, followed by an inferior cable (in AWG (conductor thickness) as well as construction) which has nothing whatsoever to say about or do with the way an AC/DC power supply works in an average user’s home nor does it address the fact that MOST if not ALL home audio equipment will never need to draw the peak amperage that they demonstrate. That’s just one example. There are many others.

When links are posted to previous studies or comparos, those are denigrated as "14 years old" (as though power cable technology has changed? If so, please note how) or that the person making the post wasn’t a direct participant in the test, which is why the new test is being proposed in the first place. So, until then: https://hometheaterhifi.com/volume_11_4/feature-article-blind-test-power-cords-12-2004.html remains the standard.

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.

And if you’re just interested in reading about the history of this type of debate without having to learn about the imaginary business fortunes of individual netizens who claim to be able to throw away $25,000 *because* they were/are a successful businessperson, here you go:

There are plenty more out there, and the vast, overwhelming consensus, is that you don’t need to spend a fortune on cables (and not much AT ALL on power cables or digital interconnects), nor will you hear any actual, non-placebo effect improvements if you do, but feel free to spend your money however you want.  And to be perfectly clear, on speaker cables and other interconnects in the signal path, spending more money DOES improve the sound - but only to a point well below $75/ft.

>>>>>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.

You’ve gone all Pee Wee Herman on us, Geoff. "I know you are but what am I" or "I’m rubber you’re glue" are not valid or particularly constructive arguments.

If, on the other hand, you’re agreeing with me that proponents of expensive tweaks and AC power cables are indeed engaging in all kinds of ad hominem because they cannot articulate or elucidate any measurable or repeatable improvements, and your most recent post was just a clever parody of this behavior, let’s start reporting these "psuedo-______" people to the mods! They’re disruptive!

If I’m wrong on both counts, please enlighten me and point me to the scientific experiments that I am not acknowledging, whereby AC mains cables have been shown to make an audible difference in a controlled environment or with full transparency to the listener as to what was being changed?  

I've been commenting in good faith here up to and including the links I've posted that point to actual tests which have been conducted. If you're here in good faith, please point me to the objective tests which prove the opposite and we can agree to disagree or I will admit that I'm wrong. 

I added this sentence to my previous post just after Mr. Itchy Trigger Finger posted.

I made an edit to my post. Sue me.

Pot calling kettle black may be a better term for what you’re engaging in here. This ring any bells? https://forum.audiogon.com/discussions/do-cables-really-matter/post?postid=1593624#1593624
