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.

@bigtwin,

I found this to be helpful to understand the pros and cons of AC wiring:

Integrating Electronic Equipment and Power into Rack Enclosures

Optimized Power Distribution and Grounding for Audio, Video and Electronic Systems

See below page 11-13 for different types of AC power wiring. Good luck with your new room! 😎

@knownothing  Bingo. You nailed it. Comparison on your own equipment with other good equipment and good power cables.  When done as you did, the difference is truly not subtle.  I didn’t believe it until I did it myself after my equipment had improved to a reasonable level.  

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.

@hickamore It definitely made a positive improvement compared to using only one power bar for my setup. I had purchased the Chang Lightspeed with the intent to upgrade from my original Furman. I tried bringing everything over to my newly acquired power bar, which did make a nice difference. But then I’d remembered other threads where this was mentioned and put just my digital components on the Furman. Everything was even better. 

My first experience with upgraded AC cables was with the Synergistic AC Master Couplers in the nineties.

I use a full SR loom in my $100k system, many purchased used as others upgrade. They continue to innovate. I'm extremely happy with their offerings, especially at the more entry level.

Very high value if you have a sufficiently resolving system...
