Did anyone return a PSAudio Powerplant? Why?

I considered one and then realized: I have no evidence that my line is dirty. I don't hear a lot of issues but without a more precise technological tool to test my line, there are other ways to spend big $$s. 

In some situations, the Powerplant may be a godsend.

In other situations, the Powerplant may be an expensive solution looking for a problem.

Without a reliable way to know which one you have, there is a fair chance you can waste a bunch of money.

My close friend did not return it but sold it after couple of months he bought it used because he couldn’t hear any SQ upgrade from his system. It was PS Audio Power Plant P600. 

I ordered a Power Plant 3 yesterday. So will have it for the next severe heat wave. Will post my experience. Plan to use it for my Streamer, DAC and Network Switch. The Streamer and DAC appear to be the most sensitive to power issues. 
 

since it cooled off my system is back to nothing but I know one temperatures get above 90 for days the power will suck and my system will not sound as good. 

Great question. Sure not getting many folks jumping in who have returned them.

I didn't return my P12, but after having to send it in for warranty repair for the second time, I decided to try an AQ Niagara 5000 conditioner.  Immediately loved the AQ.  My highs had returned and everything was much, much more dynamic.  It was like going from a modern Led Zep I remaster to an early 70s Piro pressing.  Or a LZ II modern remaster vs an OG RL pressing.  I could not sell the P12 fast enough.  IME, power plants (had a Stellar PP3 briefly before the P12) definitely truncate the upper treble frequency range and compress everything.  I just didn't know it until I heard what a high quality power conditioner could do.  I know Paul is proud (as are many other members of the PSA forums) that his stuff sounds 'more analog' but IME, it's not the good type of analog (ie. rolled off highs like many MC cartridges are guilty of).
