PS Audio Power Plant or Power Plant Premier

Your findings are encouraging.Based on what I read,the powerplants shouldn't be used on amps anyway.I thought of getting the P1000 myself.

Get some dedicated 20 amp circuits and try again, this will be the biggest upgrade you can do for little money comparitively. The newer PS audio doesn't regenerate the whole AC sine curve like the older units hence they can power more watts and don't generate so much heat.

Does your Powerplant have the Multiwave 2 module in it? I found this to be definitely better than the standard when I owned a PS300.

Don't waste money on the P1000. The PPP is much better. I never have good result with a lot of other line conditioners before while using with my powered 350W ATC speakers compare to straight to my dedicated 20A circuit.

With the Duet appeared 1.5 years ago, thing has changed. My ATC speakers can't live without the Duet any more. The mid and bass are much better than going straight to my dedicated circuit.

I just purchased a PPP to replace the Duet just for my ATC speakers. Same thing, just better than the Duet of course.

Good luck in selling your P1000.

Mine is a Cullen modified P1000 unit (stage 2). I have only tried the sine wave option. The unit has all multiwave and clean wave options.
Also, from feedback, it sounds as the old one (P1000 etc) is the only one that does true regeneration. Balanced power.
Maybe the new one (Power Plant Premier) has better filters and works better in home theater with a large screen TV.

My partner had numerous PPs 300/500/1000. I now have a PPP. He says it's better!

I also agree, get a dedicated line. AND check for hot/neutral. My "electrician" had them reversed!
