I'm not at all suggesting the input coil topology be changed, as this may actually have something to do with the "magic" sound of the PurePower -- something like the special sound of Fender single-coil pickups on a Stratocaster.

Drdna, what you express is exactly how I feel about the PP units. I personally do not feel that PurePower was “designed for sound”. I think they took some kind of genetic on-line regenerator, optimized it “for sound” from point of view of common electric sense and desired to market it as audio-optimized regenerator. Whatever was in the units originally or whatever was done to it accidently make the PurePower to sound very good. I do insist that the finding was accidental and I have very high suspicion that the PurePower people have no idea what it is. I did ask many times Richard the question why he fell his unit sound so good. He was very confident that he knows and gave me different reasons but honestly I do not buy them. The entire concept of converting PS into a switching topology, or so called digital PS is not new. There are zillion companies that experimented with it, some did better, mostly worse. I remember Ed Meitner promoted digital supplies to his earlier DACs but the result was not good. Perhaps a switching PS with following galvanic decoupler (transformer) is the key but who know? You can connect many switching PS but they will not necessary will sound like PP. This is why I am a bit skeptical and with big worry hear news that PP did some improvement. I do afraid that they change something that is not “important” and the sound goes to toilet.  From a different perspective they do maintain the PurePower unit over 15 years from 1.5kW to 3kW+ and the sound become gradually better in my view, so go figure… 
 
What I know is that from where I stay the sound of any playback without PurePower is not as good as it could be. Over the years I maintain a very persistent outlook. I might read some kind of audio review of a super-duper playback installation for near million dollars and I see how a review in his writing suffocates himself in orgasmic convolutions, impressed by the quality of sound. Do you know what I feel when I read it? I feel: “Ok, but you never heard the same playback driven by a properly functioning PurePower.” This is so radical to me.
