I heard a difference with Shunyata Venom 10 NR - I acquired it for $350 as a demo. I was 'lent' it to see if I noticed and appreciated the difference - it did and for me it was worth the price.
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.
