Which power cords have high resolutions and separation??

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

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

anything OCC single Crystal will be the best sounding power cord.

In my experience single core beats Litz everyday in terms of leading edge and impulse response. Think Acoustic Revive, Nordost. Also using an Add-Powr conditioner is a highly cost effective way of upgrading the supply side

Power cables do not affect audio quality
