John Atkinson (Editor of STEREOPHILE) tried the PP with his 380S, and claimed it narrowed the gap between it and the Ref 32. See the Power Plant review in Stereophile (or maybe it was the followup on the multiwave mod...not sure.)
Myself, I've been using a P300 for six months, and am delighted. My wife, who's not an audiophile, noticed the same differences I did.
