PS Audio Regenerators - P5, P10, P12, P15


Currently I have the P5 powering my front end 2 channel system. Amplifiers running directly from the wall as is subwoofer. Separately I have a projector that I was running off of a Pure Power 1050. The Pure Power unit died and I don't want to get it repaired (too many horror stories). I am looking at either a used P10, new P12 or new P15. The P10 or P15 would replace the P5 and I would connect the projector and subwoofer (JL Audio f112 v2) to the unit so all my equipment except the 2 channel amps would be connected to one unit. A P12 would be for the projector and sub only (so I would have a P5 and P12).

Money is obviously a factor if I go for the P15 as with trade in it still costs $5,000. A used P10 is under $3,000. Any thoughts?

I have the P20 and leave it on all the time.  The only components I partially shut down are the BHK pre and 300's front ends to save tube life.  I had twin P10's prior to the P20 and followed the same protocol. I do believe my system sounds best fully warmed up.

To the OP, I would sell the P5 and buy a P20 and plug everything into the P20.  I have twin subs, mono blocks, electronic crossover, pre, dac, and two other front end components plugged into it and run the P20 at 30% of it's capacity. I have always made out better selling my gear personally and buying right through a dealer.
P15 here. Love it and run TV and all 2 channel, except my sub. Drawing less than 5 A at normal levels. 

I'd expect a P20 would sound even better but it's a step up in price I couldn't  do

Leave mine on all the time and leave my system in standby
I leave it on all the time.  Find the music sounds devine almost from the start.  And I do have my subs on it. Had to buy the P12 in order to accommodate them, but definitely worth it.
