PS Audio P15 power conditioner vs Accuphase PS 520/530?

Just saw this thread. I’ve been selling off my system and my PS520 is coming up for sale next week. Difficult to see PS Audio at this level but who knows. All I know is that it measures line distortion in followed by zero distortion out. I’d suggest reading up on it. Positive Feedback did a nice review a while back. 

I've enjoyed PS Audio components now for over three years.  My last upgrade was to trade up from their P10 power regenerator to the new P15 model, and I found an immediate improvement to the bass, soundstage and clarity in the highs, both from my PS Audio DirectStream DAC and my Mytek Brooklyn DAC.

I haven't had much need to contact PS Audio for support, but the few times I have, they have been outstanding!

Thanks ejr,
 I've heard nothing but positive statements about the PS Audio P15.

Go and take a look at my system page.

I've posted some waveform shots. There are a few with different PCs that give you a glimpse of the actual mess that is coming in from the utility 

You can also see what a clean form comes out. Especially at the peaks.

I've decided to go with the PS Audio P15.  Thanks to everyone for taking time to respond.
Musically,
