Best Power Conditioner

I use Bybee quantum chargers (there is tons of junk on my lines) in front of two PS300 (one for digital and one for analog). I use 90 hz setting. They are plugged in across two legs of a 240 circuit for a balanced input. I guess I'm lucky but mine are silent. I have a seperate floating star earth ground right outside the listening space. This made almost as much difference in my case as all the power stuff.

PS Audio Power Plant makes a bigger improvement in sound than almost any component change.

I use the Chang Lightspeed CLS9600 ISO which replaced my Chang CLS6400 ISO that I now use for TV,DSS receiver and VCR.I really like the performance of both units.

I previously had my entire system plugged into a API Powerwedge 116. I was intriguied with the talk about the P300 and bought one. It was a major improvement over what I was using. The Powerwedge did seem to reduce the noise floor, but what I didn't realize was that it was muffling the dynamics and sort of greying the sound. I was of the mindset that the powerwedge must be better than nothing. I left my amps plugged into the Powerwedge because the P300 can't produce enough power to power the amps. What I was really amazed to find was how much better my system sounded when I plugged the amps directly into the wall. It really made my system more dynamic and lively. My point is don't assume that a power conditioner will always be better, I do agree with the others that the PS Audio Powerplants do make a big diffrence however. Also Carl is right about the hum that the produce, it doesn't come through the speakers but directly from the unit. I can barely hear it from my listening position which is actually kind of irritating
