Which power cords have high resolutions and separation??

@nasaman Audioquest latest Storm series Tornado is excellent for an amplifier. If you can increase your budget and go up to Hurricane it’s even better.
On a lower end of the price range, TWL Seven Plus has a very open sound but it won’t come close to AQ in the overall sound quality and lower noise floor. 

I’d recommend taking a look at the LavriCable Ultimate silver PC — about $500 new for a 2m cable.  I don’t have their power cords but some other folks here do and they’ve been really happy with them.  I’ve got their lightning/USB dongle (that kicks the crap outta the Apple Camera Adapter), balanced interconnects, USB, and balanced headphone cables, and they all manage to provide lotsa detail in a natural way with excellent and transparent imaging/soundstage while also offering very good tonality.  It’s a pretty impressive balance of traits actually, and maybe other members who have their PCs will chime in here too.  I think they offer quite a bargain for the performance they deliver and using 5N quality silver wire.  Just another potential option to explore, and best of luck. 

Thank you all, friends.
