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 P15 is a regenerator not a conditioner.  Huge difference.

 I have a P15 and love it. Massive impact on my system . 
I had an original PS Audio Premier Power Plant. I suspect their new PLCs to be much better, however...

See Core Power Technology. I have their 300 powering  my TV and an 1800 in my main audio rig. Soon I will get their Deep Core to compliment the 1800
Thanks doitwithlife. I've been quite impressed with reviews of the P15. I figured that I'd investigate the Accuphase because I have their integrated amp.  But you're right, a regenerator is a different beast than a conditioner.  Seems to me that a reconditioner would generally be a cleaner option.Thanks.

tweak 1- I will look into Core Power Technology also. Thanks.
