Power cord? Why?

Thank you Sean. I guess there is no point for me to change from 12 to 10 since I don't really have a dedicated line for my stereo system. The power cord I need is only less than 3 ft long anyway. Like what I observed from 14 to 12, there probably will not be much difference from 12 to 10 in this case.

Sean - what I heard from Roger (via my dealer) is that he is concerned about the capacitance of the speaker cable resonating with the transformer windings of the speaker. I don't believe he is concerned much about the amp oscillating. I believe Roger has a treatise about this on his website.

Corona, I agree with you completely. My brother is a metallurgical engineer with 25 years experience. He has taught me a lot about this. This is why the wire needs to be fabricated properly and handled carefully in the assembly process. This is how my "Perfect Crystal" stays perfect.

S23Chang - the equivalent wire gauge is what is important, not the gauge of a single wire. Low inductance cords are always made using multiple wire to get that low inductance. Resistance is only one piece of the pie. Inductance must be low as well and larger gauge just does not get this for you.

Audioengr, tks for your reply. I'm using twisted pair of 12 total AWG wires. I was thinking about doubling that and get 9 gauge.
