After Market Power Cables - Gold or Snake Oil?


Myself and a collegue of mine have been discussing the potential benefit(s) of using after market power cables with hifi equipment. I claim that since the majority of home owners gain their power from the everyday wall socket, how does the addition of a short length of 'expensive' cabling make any appreciable difference to the sound quality. Are we kidding ourselves and buying into marketing hype or is there some scientific truth to the matter? I am a musician/recordist who understands the fundamentals of electricity and sound reproduction.

First off,thanks for all your responses. You have provided a lot of fuel for the friendly argument my friend and I are having. (fuel for him , that is!). For the sake of argument, let's look at a typical a/c path. Edison delivers 110 volts to your breaker box. That goes thru a 20A circuit breaker to about 50 feet of garden variety 12 or 14 guage copper wire. Said wire is terminated with a good quality 3 prong outlet box. Hot, neutral and ground are all securly connected. I don't see how adding 5 feet of any esoteric cable can possibly have any sonic benefit. It seems to me that finding an outlet 5 feet closer to the breaker box would provide as much of a theoretical improvement. If not more. *ASUMMING* that the power cord is at least as good as the house wiring.
Audioengr,
If i read your post correctly, the same results would be obtained if the run of ROMEX were 19 ft, and the 6 ft. P/C were at least as good as the ROMEX?

Just thinking...
Redkiwi,
Why ask why, you ask. As a musician/serious amature recordist, believe me I have seen more than my share of "floobie dust". Like the time a guitarist was dubbing in some "fills" for a soft rock piece that had already been recorded. After the first take, the producer said he thought the performance was great but he did not like the sound of the guitar, did the guitarist have another he could try. The guitarist said yes he did (tho in reality he did not). He set the guitar on the floor (out of the producer's sight) waited a few seconds, pucked up the same guitar, played the same fills and the producer thought the sound was perfect.

Or the time a mixing engineer was tweaking the compressor on a vocal track (in the presence of the vocalist). Only after the settings were thought to be "just right" that the engineer realize that the track was not even being sent to the compressor!!

Sometimes changing things changes sound for reasons other than the changes.

I have neither the time nor money to A/B a dozen $1000 power cables.

That is why I ask why.
Redkiwi,
No, when I ask you "why" I am not saying you are deluded, I am just asking if you really know what phenomenon caused the sonic difference you hear. Psycho-acoustic effects, like optical illusions, "feel" like the real thing.
This is in no way the product of "delusion" as clinicly defined. It happens to everyone.
I know this is true because I have experienced it myself.
(the "compressor" story in my last post)!!

I am not trying to be contentious, I would just to like to know why people are hearing what they are hearing.
