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

Iasi - I understand that Roger contracted Coda Technologies to design the Innersound amp for him. Same guy that designed the Coda and Continuum amps. I have heard from one of my dealers that Roger is not a cable believer, however he does spec a low-capacitance cable for his speakers.... It is hard enough to convince believers.......
Audioengr, i believe in speaker cables and in interconnects as i've herd differences between diff. cable manufacturers...and i believe in power cables for SOME applications, but not in all of them...happy listening!
Due to the design of the Innersound amp, which is somewhat similar to the older Threshold's in terms of design theory for the active circuitry but not power supply, the amps will go into oscillation and self-destruct if you use a high capacitance speaker cable with them. That is, if you don't use Impedance Compensation networks with the high capacitance speaker cables. Roger does not like very high capacitance speaker cables and, from what i've been told, thinks that they are an "abomination" of some sorts. I've also been told that running very high capacitance speaker cables ( like Goertz ) with the Innersound amps will void your warranty. Sean

According to Phelps Dodge research dept. continuous wire is more of an exercise in marketing than reality. Once the wire is bent it has as many fissures as any other copper wire. Remember, copper is a crystal and all crystal structures are brittle.
Does it make sense to use greater than 12 gauge for the power cord since the outlet itself to the breaker box is only 12 gauge? In most cases bigger is better. However, if the outlet can only give you 20 Amps then what's the point of using a 30 Amp power cord since your device is drawing less than 6 Amps anyway?

Anyone did A/B test with 12 gauge vs 10 or 8 gauge? I've compared 12 vs 14 and it doesn't make much difference. 12 gauge seems to give slightly better bass than the 14 but not by much. From my own A/B test, the difference is no greater than 2~3%.
