I use all Lessloss pc's, except on my 2 power supplies(Lingo and Lehmann Black Cube). I tried my one Lessloss on all my stuff-to determine how many I wanted to get under their special deal. When I got all my Lessloss pc's(4 altogether), I tried my last 2 on my Nuforce 8.5V1, that had V2 power cords on it. When I did so, a certain synergy occurred. I found that they benefited my Apl Denon 3910 that I use as a transport, my Oritek pre/dac, and my Nuforce amps. They beat Volex 17604 and Valab silver pc's(which means I was a novice). I wonder if they would benefit my Nuforce P9?
