PS Audio Direct Stream P12 Regenerator versus Puritan PSM156 Master Purifier

I have a PS Audio P12 Regenerator.  I just added a Bel Canto ACI600 to my system.  The power cord from the ACI600 to the PS Audio P12 lost power.  I reset it, and it worked.  It was recommended that I replace the PS Audio P12 with a Puritan PSM156 Master Purifier.  Any experience or thoughts on this would be greatly appreciated.
