Williwonka's DIY SPIRAL HELIX. Wires provided by fellow Goner, which I assembled with spare plugs for positive difference. Also tried a bulk audiophile recommended by a you tuber, with negative difference. Connected to pre-amp.
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.
