Just adding on this older post. The Sain Chord power cable on my ARC pre-amp has been/is a game-changer for my system (Wilson Audio + ARC Ref + Lumin + Transparent Super cables/ICs).
It made a similar, but greater, enhancement than going from Transparent Super to Ultra speaker cables. I would say the same magnitude of change as when switching from Ref 3 to 5se preamp.
If you have ARC, and are thinking of upgrading speaker cables, you owe it to yourself to strongly consider grabbing one of these power Chords from Sain first.
