Power cord? Why?


I see a lot of posts regarding power cords. I would like to know what sonic difference they actually make. Could anybody explain this in a simple way?

Thank you

sean....Aw shucks. I am just beginning to get interested in this PC thing. Since the original Kenwood PC are so "crummy" I won't be wasting my time replacing them, and I will do it with multiconductor configuration that you suggest. I checked out listings for power cords, (I need 2) and it seems that your idea of a few bucks is different from mine.

If I can figure out how to send you an attachment (test plan with diagrams) with EMail I will doi it.

Thanks for your constructive comments.
Eldartford - you can buy hookup wire at: alliedelec.com

Copper quality matters, whether it's power IC's or speaker cables.
Iasi - I have had the Innersound ESL amp in my system for a couple of weeks. I know the design of this amp (by Coda Technologies) - no negative global feedback, strictly class A/B and lots of protection fuses etc.. - however, you have to be careful about removing IC's before it's fully discharged. My power cords definitely made a difference with this amp. Maybe you have not tried the right power cord yet.
Hbarrel - I will not be driving from Oregon to Akron, sorry. BTW - Power cord effectiveness has little to do with how clean the power is.... See my FAQ page at:

Audioengr...talk with Roger Sanders at Innersound and tell him that power cord made a difference with his amp..I wish I could hear his reaction when he hears/reads that...now, how do I suppose to know which power cord is the "right" power cord?....i wish someone could publish a list of "right" power cords and "not-so-right" power cords...i'm sticking to my beliefs: a well-designed/made power amp does not need a power cord...
