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.

The Accuphase looks like an implementation of the Pure Power idea, one I first saw from the guy who makes Jensen audio transformers.


It's very neat and very efficient.


It tracks the incoming waveform and actively corrects it. As a result, it is high current, and high efficiency, without resorting to an AC--> DC --> AC reconstruction process like PS Audio uses.


I can't tell you how it sounds, but if it has the Accuphase label on it in the US I'm sure it's expensive as hell. :)


I'm not sure if PurePower is still selling or not, but if you are interested in that technology they are worth looking up.
