At some time I owned a PSAudio P10 regenerator - the output distortion was always less than 0.5%. The new PSAudio P20 also lists THD < 0.5%, output impedance of < 5 milliohm, 85% efficiency, maximum continuous load 2000 VA.
Probably it could be powered by lithium batteries.
Surely. But the PSAudio use a linear power supply to create DC and re-generate the mains from this DC. In principle they could be operated by batteries.
