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.

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.

For me it was a Cerious Technology cord one of the early ones I forget the exact model.

I acquired two Zu Mother power cords for my Shanling EL34 based monoblocks years ago and the improvement over the original factory cords was audible. I have never forgiven Zu… 🤣
