Which power cords have high resolutions and separation??

@nasaman , I think you start from the wall and work your way forward when it comes to power. I would recommend trying an outlet (pangea, synergistic research, etc) first (about $100), and after that maybe a power conditioner (Black Lion Audio, Add-POWR, Audiolab DC Block, iFi, etc). I think you could do both an outlet and a power conditioner that would impact all of your components with your budget. As for power cords I saw a review of the new iFi cords, I haven't tried them but they look interesting:

OP, I would build a power chain starting with dedicated line if you can, then a nice outlet (Pangea/synergistic research/etc), a power conditioner (I like Black Lion Audio which is available where they sell pro gear like sweetwater), and then a power cord. I don’t think you should get a power cord without auditioning at least 3 so you can appreciate what you like and don’t like.
