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


I want to add a power conditioner with my study system.  It consists of an Accuphase E-550 integrated, AMR DP77SE DAC, & Ridge Street Audio Design Sason speakers.  I feel no need to change components.  I'm debating between an Accuphase PS 520/530 or a PS Audio P15.

Has anyone compared the Accuphase and PS Audio power conditioners?
Your thoughts are appreciated.

I owned the Accuphase P1200, purchased new. It was very very nice on front end gear but on amps I could definitely hear it limiting the dynamic range, this is why I sold the unit. My PSA P10 powers one of my systems completely including an OTL amp and the 300B. Absolutely no dynamic compression and it sounds amazing. Soon to purchase a P15. As a former owner of the Accuphase I don’t find a disparity in build quality, different yes but my P10 is aesthetically very nice.
