"An Accuphase Clean Power Supply totally regenerates the AC into a perfect waveform (ultra-pure and totally stable). "Uumm, no it does not. It uses "waveform shaping" to correct the distorted AC waveform. It uses a regenerated AC signal as a reference and then applies correction to the AC output.
Don't get me wrong, the Accuphase is a killer unit and I can't argue with U that it is one of the best AC correction products on the market BUT Total and complete AC regeneration it does not provide.Only PS Audio offers units that completely regenerate the AC waveform.

I've used an Accuphase PS-1200 for many years and have been very happy with it. You are correct that it performs "waveform shaping" rather than "waveform regeneration", but I think that this is actually an advantage. The unit runs just warm to the touch even after hours of high-volume listening. I've read that the PS Audio units run hot enough to fry eggs on.
"I've read that the PS Audio units run hot enough to fry eggs on."
That would be the PS Audio PP-300 which does run hotter than a bullet.My PP-600 does run warm at full throttle but is still does not even approach the quiescent temperature of my Pass Labs Aleph 3 amp :-)

HowdyBut waveform regeneration doesn't have to be inefficient...
"But waveform regeneration doesn't have to be inefficient..."Your right, it does not.
Witness the PurePower and the new PS Audio Power Plant Premier which uses AC regeneration on the front end but a digital switching power supply/amplifier on the output.
I still prefer old fashion class A/B amplification for my power purity :-)

futhermore . . . something cannot be ultra pure. It is pure or it is impure, like . . . say . . . Madonna.

Likewise something is stable (like me, for instance) or instable like George Mann or some other inmates ;-)
sorry . . .unstable
HowdyYou said "Only PS Audio offers units that completely regenerate the AC waveform."
PurePower seems to do one (or two) better than PS Audio or Accuphase: http://www.purepoweraps.com
I don't have one of them, but on paper they look good.
"PurePower seems to do one (or two) better than PS Audio or Accuphase"PS Audio has a full description and performance specs on their website for the Power Plant Premier and can be perused at the link provided.
I am sure any of these units would perform on almost equal footing when compared to each other AND there would be NO comparison when pitted against what our local power company sends us!!!

HowdyEspecially since I've never owned a PS Audio power conditioner or a PurePower product... But:
As to equal footing: it's not clear how long the PS Audio runs with no AC input :)
Also it's clear that many of their claims about their competitors are false given the specs from PurePower, perhaps they don't know about them? (Actually I don't believe that since they've incorporated some long standing PurePower features into their new product.) And don't get me started about MultiWave...
I still like the PurePower on paper better, but how do you know till you listen?
