Which power cords have high resolutions and separation??

And, I’d recommend not using a power conditioner on the power cord, sound degrades

Start with a dedicated 20AMP circuit $300), add an audiophile outlet $150 (PS Audio, Cardas, Furutech GTX, Oyaide R1 or SWO), add the power cable of your choice. The dedicated circuit and outlet did more to open up the sound in my system than any cable I tried or use
