PS Audio Power Plant or Power Plant Premier


I recently bought a PS Audio Power Plant P1000. The high end stereo shop said the old model - US made is much better than the new China made "Power Plant Premier" for Audio.

Has anyone compared them for regular two channel audio?

My finding is that the unit only improved digital playback and not pre and power amplification.

Thanks

Haven't tried the big power plants, but FWIW, in my system the PS Audio Quintet only improved the digital very slightly, and was very detrimental to analog playback. Perhaps the power plants are different, but I would not recommend the Quintet.
If Quintet is not good for your analog system, then you can at most say Quintet is not good for analog system. You can't make a general statement like you would not recommend the Quintet.

I have all solid state system and the Duet, Quintet, Quintessence and PPP all make my system never sound this good before.
Did any of you find that the PPP had to be broken in or did it perform right out of the box?
