Any opinions on PS Audio Power Plants

I have the P300 as well. I started out by running an Xtreme Statement into a HC/UO, then another Xtreme Statement to the P300. Plugged in to the P300 were my tube preamp, CD transport, DAC, and tube phono stage. I only used the 60/120 settings on Sin wave. I never really used the Multiwave options, at least not to this point. I think the system performs well, but the fan does come on after about 30 minutes and the P300 still runs hot even though its on an amp stand not the floor.

Today I reconfigured. I run the P300 from one wall socket with only the CD transport, DAC, and tube phono stage connected. The HC/UO is in a second wall outlet with the tube preamp plugged into it. The tube amp has always been in a separate wall socket with the power filtered by a Chang Lightspeed (soon to be Running Springs Duke).

I am going to play around some more with the Sin wave settings. If any one has any suggestions for me to try I'd be interested in hearing them. I also upgraded to Multiwave II+ and I like the Clean Sweep demag function. I would recommend the upgrade and it's pretty easy to do yourself if you exercise some patience and follow the instructions.

Photon45,
The noise in the fan is what got me to upgrade to the P-500. Much quieter.

I upgraded to a P1000 recently. I was able to plug everything into it's regenerated outputs from the CDP to my Ayre amp and it has been pure music bliss :-)......

I have had the same problem with the fan noise in my P300.I have called PS Audio and was informed, that you can safely disconect the fan, unless the power meter on P-300 doesn't read above 100W.

I run it with no fan with no issues at all.

The other solution is to install a super quiet, HQ fan you can get in computer stores. Super-duper Papst fan should set you back around 20$ and will be dead quiet.

I also have had the P300 for over three years now with nothing but great performance improvement on all my front end components. I replaced the fan with a super quiet Pabst fan and I can barely hear it. Plus it makes the unit run a lot cooler compared to running with the fan disconnected, and for electronics, that is always a good thing. Try the experiment sometime and take it out of your system. You won't keep it that way for long.
