Does an aftermarket power cord matters for Amp?

Hi Steve. I responded to your system post before. I am a believer in the benefits of better power cords because in my system they make a difference. I recently went through a cable downgrade, $$ wise, but have found some really good cables cheap. Check out ErnieM's (aka Subaruguru) power cords. I recently got his new Prelude No. 13 in Cu, and it is really great! I recently sold off my shunyata and electraglide cords and got his and don't feel I've sacrificed quality. I do find that changing a power cord anywhere in the chain makes a sonic difference and have yet to find that a stock cord is better.

With all due respect to you Warrenh, I think you are referring to Ernie's older models.(which I have owned in the past) This new incarnation is another league of power cord and more than just an "introduction". He has changed the cable and the design. It is a class act and though I have never sampled the heights of the harmonix cords, I have compared it to a shunyata black mamba V2 on my cdp and I prefer Ernie's for resolution, depth, and transparency. There was much more of a "difference" and that difference was all good. Whether it be synergy or good design, it's well worth the $160. IMHO.
