Kind of late here, I tried the Nuprime AC4 and it was really great in my system. But I returned it because just 4 outlets was not enough for me. I thought it would be perfect, I was wrong about how many outlets I would need in the future.
I tried the Audioquest 1200 and didn't like the sound as much as the Nuprime. Switched to PS Audio P3 and it had reliability problems. Finally landed on a Torus that does a good job. I would have like if Nuprime just made a bigger version of their AC4 though.
