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

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,

……. I have owned both; The Accuphase from a sound standpoint as well as just build quality and parts is just in a different league all together.
