Blue,
Have you compared with and without PS audio using same power cords to amps? I would expect differences at all volumes.
Can't draw any conclusions in lieu of hearing but on paper, p1000 looks like a pretty hefty beast, but only 7 amp current delivery per spec sheet I can see. 600W bryston delivers significantly more current than that I would bet.
My guess is results are a mixed bag of +s due to the device noticeable largely in midrange and higher and -s due to more limited current delivery, which I would guess might limit impact or meat on bones of bass perhaps. Either might sound better depending......
