Which power cords have high resolutions and separation??

+1 on Acoustic Revive, especially power sensual 18000 if you can stretch your budget (including good quality plugs).

Regular 16 gauge and 20 gauge cords.

Don't waste your money on anything else.

For power transmission and supply....wire is wire.

I built my own with Furutech components. That way I was able to get custom lengths. FWIW

Furutech FP-SO 22 N or FP-SO 32 N

I own several and they are very good and come in under $500. Message me for more information if you wish.
