Which power cords have high resolutions and separation??

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.

+1 on Furutech. But there’s a catch if you want to make/terminate these cables yourself - if for whatever reason you will want to sell these “DIY” power cords, you will take a very hefty hit and it won’t be as easy to sell as for example AQ or Shunyata, etc. 

But…the upside is you can get top notch wire and connectors. I’m using Furutech FPS-055n with FI-50 NCF connectors on preamp and FP-S032n wiFI-28 Rhodium connectors on DAC that I assembled myself. While the 55n is a really nice sounding cable with NCF ends for the amp, I still prefer the AQ Tornado hi-current on my amp. 

naaman, as I recall you are in the Bellingham area an hours drive north of me. Come on down, I have M101 Supernova and more you are welcome to compare.

Nonsense. Gauge matters. A 20AWG wire isn't sufficient for a 120VAC 15A line. Period.

Material also matters

As usual on this forum, you’re on point.
