I do think it is possible, yes. Did you read the part where I discussed double-online conversion? PS Audio's Power Plant 1000 is awesome (loads of features), and is a true "AC regenerator" as their product page says: http://www.psaudio.com/products/p1000_overview.asp

"A true AC regenerator takes the AC power out of the wall, converts it to DC voltage (like a battery), then re-manufactures perfectly clean, harmonic and noise free AC that you can then use to power your equipment."

Sounds like you answered my question, there is an audio product that uses true double-online conversion. They just call it regeneration.

At UNISYS we sold lots of UPS's and not one outputs audiophile quality AC.
Need some power protection? Some AC line noise isolating?
