I use a PS Audio P-300 regenerator on my front end devices. The older power plants are balanced, the newer ones like the PPP are not. I don't like regenerators for amps or high current devices. I could not live w/o my P-300 it makes a great difference. If I were you I'd pick up a used P-300. Realize there are many incarnations: No multiwave, Multiwave, multiwave II, upgraded w/gain cells and newer caps, better AC ports, remote control. I still believe the 120hz sine wave sounds best. Also my Oyaide R-1 WITH a WPC-Z cover plate makes a huge difference in AC delivery as well. Good luck.
