Like almost anything, I really believe this is more a matter of taste than anything else. Oddly enough, I tried a couple of cords for my amp (mostly in the 100-200 dollar range), and while most of them highlighted something in the mix, I prefered the stock cord for long-term listening. I think a good way to go about it is first, ask yourself what it is your trying to accomplish by purchasing a power cord, second, set down a budget, then third, try a hell of alot of them out in YOUR system. I tried about six. the last one I tried was the only one that after day three (ie after the nostalgia wore off) I really liked. That last cord was the ESP Essence. About two hundred more than I wanted to spend, but I've never grown tired of it. Anyway, every cord maker will have some 'technological' claim stating why their cord is best, but 'best' and best for you don't always met eye to eye, so try as many as you can, and decide which is best for you.
