The only under $500 power cables that I found a noticeable improvement from are Audio Art Cable power1 Classic, and power1 e Croy. Had tried Signal Cable, PS Audio, and a few others that were no better than the stock equipment cords.
What was the first power cable that you noticed a difference in the sound?
I have bought six or seven different power cords, none over $500 and have noticed little or no change in the sound of my system. All the cables are 12 gauge or bigger. Without talking about cables made with unobtainium, where did you start hear a difference.
Thanks.
