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. ??

Thanks for that link. As I suspected, Shunyata is doing work to clean up electrical signals on medical imaging equipment cables. That’s legit, and so are power conditioners such as those AQ is discussing in your other link.

There is still zero evidence presented for why a power cable ALONE can do anything whatsoever for audio and I will say beyond a shadow of a doubt that Shunyata’s medical supply business unit is NOT using $1,000+ AC power cables for their image/waveform enhancing equipment. So in itself that kind of shoots down the legitimacy of their own expensive AC cable business. Also, they aren't very specific about WHAT they're doing for these medical imaging issues - and I'm sure if they were under contract to one of the big MRI or other imaging firms, they'd be all about letting everybody know. Still....no way in Hades they're selling hospitals $1000 power cables and that's something I'd actually bet money on right now. 

Audioquest has a documented history of falsifying results or at least letting their resellers do so and then take the blame when caught. Their power cables alone (I’ve never made a statement about power conditioners) are bogus and will not enhance ANY audio system, but the conditioners have a legitimate purpose, even if theirs and Shunyata’s (as compared to say Furman) are way over priced.

So you’re on a mission. You’re an audio Knights Templar, out to save the world from itself and destroy those who oppose you. Got it.

No. Once again your powers of perception and interpretation fail you. Perhaps you’re not the Internet superhero that you present yourself to be?

I’ll be on the regular forums where I’ve been involved for the past 5 years and contributing to the blog of Dr. AIX (often anonymously since that’s the nature of his comment software/platform) and on various social media Hi-Fi groups and platforms as well as offering advice when asked about circuit design when I feel as though I can contribute.

On this topic, and since you’re suddenly so concerned (given your years long membership here and "only" 3,000+ comments), and willing to offer up insulting and quasi-condescending predictions for others including me, what exactly are YOU trying to accomplish here - on THIS very thread? Do you have anything to say about AC power cables or NOT? LOL...pot meet kettle again, right? Or do rules and expectations conveniently not apply to you? 

Cue up your latest report of my comment to a moderator, as you've been doing for the past day or two. Don't worry, I'm not offended, but you should try to be more honest with yourself even if you're not honest with me and the rest of the readers here wishing to discuss power cables.
