I actually sold my P300 and replaced it with a Balanced Power Tech BP Jr., which is a transformer type conditioner like the PS Audio--for about 1/2 the price. The result is that my tube gear sounds like tube gear. With the PS Audio, there was an edginess that I didn't care fore. The BPT doesn't seem to get in the way. I also have my CDP, TT, and tuner plugged into it.
