Why does an audiophile grade power cord matter?


probably another beaten horse topic but I cannot find answers to quell my question.

Basically, most of us have homebuilder standard supply solid core copper wire with nylon, plastic or rubber sheathing that runs the length of our homes from some cheapo metal utility company supplied junction box to a 5 dollar leviton outlet Joe General Contractor buys at Home Depot. So the current at that 5 dollar outlet is what it is until we hook it up to our system.

So why does plugging in a 1.5 meter or what ever length of audiophile grade xxx hundred dollar power cord matter to go that last couple of feet to our components???

I never did 'believe' in special powercords either. I tried a few homemade cords.. Then a Pangea only because it was as cheap as i could make myself.
Well, the Pangea did make a difference i could hear right off.
So eventually i bought all Pangea powercords for my IEC use electronics.
I am certain someone can come up with a BS reason which could convince others as to 'WHY' they work.

I have only my fantasy theory.. So if YOU like my fantasy theory, then you too can claim you'know' why cords can make a difference.

IMO it is the last few feet of powercords can dampen to sloppyness of the waveform, and help make it a single waveform. Reducing "SMEAR" sort of, in the AC waveform.
that is MY 'theory' of what aftermarket powercords do.

From the results of all my own fooling around.. That is the fantasy which closest correlates to what i hear when messing about whith my toys.
When adding various stuff together, or not, seems to 'thin out the sound, which I take as making the waveform so tight and thin it actually reduces the power.. Or making broad and more powerful..'See my theory sucks as soon as i try to overindulge in it.. But it works for me.
Eliz....I've heard the same thing before...and to THESE ears, the right power cord makes the most positive difference.
Why do cables or NOS tubes matter? It's the same thing as in most of audio, it cannot be explained, only heard or not heard. I didn't buy the fact that a power cord could make a difference either, but listening has changed my opinions.
If you can't hear the difference, count your blessings and move on. :)
Photonman,

Simply stated a power cord is an extension of the primary winding leads of the power transformer of a piece of audio equipment.

If the electrical panel, wiring, and receptacle are the weak link in the power delivery system, as you suggest, why should any equipment manufacture worry about the power transformer he uses? After all the power supply converts the AC output of the transformer to DC where it is filtered and made near pure DC, right?

I suggest you search the archives here on Agon as well as the Cables and Tweak/DIY forums on Audio Asylum. You will find the answers you are looking for.
