Another PS Audio user here, dual P10's in my case.  I used a P300 back when PS Audio put out their first regenerator (late 90's), and I wasn't all that impressed (except by the waste heat - - wow did it get hot!).  The P10 is entirely a different story, delivering reliable power while generating just a bit of heat itself.  I agree with Elizabeth's general descriptions for the improvements to be had, but with the P10 I don't lose the bass output, even with my 300 watt ss Class A/B mono amps plugged in.  I get a system that does not vary so much from midday to late night, etc., and with all of the clarity and "rightness" of music.  I think they are well worthwhile.
@jbrrp1   Great point about the sound of the system not varying with time of day like it often does without regeneration!  That was one of the main reasons I bought my first regenerator, the P500, years ago.  You are right about the heat.  It was tough to run in the summer.

Oner more point I failed mention about my P5.  It does not restrict the dynamics of my system at all to run my 275 watt/ch. into 6 ohms SS amp off of it.

I'm listening right now to the Reference Recordings LP of Mike Garson's Oxnard Sessions Volume 2.  Spectacularly dynamic, spacious, just lovely sound.
PPP that I use does not restrict dynamics and makes everything better, including the dynamics. The wall current here is terrible, unstable and very dirty. My amp is 120 Watt/Ch, the entire system is plugged in the Premier. Power cord from the wall to PPP is Custom Cord Company Top Gun.
@inna   That's great!! I'm glad to hear that your PPP is working so well for you.  You are probably experiencing a significant improvement as you state you have "very dirty" power.  My incoming AC only has 1.7% THD.  From what you are saying your THD would be significantly higher than that making your PPP a true godsend.
