Power cord

It just depends on what the op needs. Does he want to warm up a bright system, does he want more resolution.  It's kind of hard to help.

I guess all these ridiculously expensive power cables will compensate for the typical Home Depot 12 AWG Romex wire found in the walls.

I like Cullen Cables a lot. They are not expensive.

Check out Cerious Tech Lumniscate power cords. I don’t know a soul who doesn’t recognize a significant bump in SQ - ESPECIALLY when used with digital gear like DACS, streamers and servers. 

 maybe I'm getting old but you guys have lost me. As long as a power chord is thick enough to carry the current without voltage drop, isn't that all that matters?
