Hifi_swlon is correct, feeding the LPS-1 with an LPSU will not make any difference to sound quality.  However, I do not think MCRU are confused at all, there have been plenty of folk on Computer Audiophile expressing a desire to feed the LPS-1 with a LPSU, MCRU sell LPSU's, the design is done, just advertise that the model with the correct power and voltage that is suitable for the LPS-1, and watch a few sales come in.  Of course there is the issue of eliminating 'wall warts' and SMPS power supplies, but to be honest, my house is stuffed full of wall warts, and last time I checked my 1000 Pro had two high powered SMPSU's lurking inside, I think you can worry about this stuff too much!  And in terms of 'gunge being fed into the mains', I can turn the Dev's up to +10dB, with wall warts everywhere, and hear nothing but total and utter silence.  (until I accidently hit 'play')

I actually made exactly this point about noise on the mains on another forum and actually stated that I could turn mine up to +30 dB and hear silence. Apparently the nasty insidious mains born noise doesn't actually appear until you play some music.... quite how it knows to start then I am unsure, possibly quantum entanglement or something simple like that

yes the noise magically leaps in only when listening to music.
The analogue output of a DAC supplied zeros by a micro-rendu is very close to being the same as if supplied straight from the computer (ie the MR adds a negligible bit of noise as one may expect) in the only scientific evaluation I have seen, so the reduction in noise causing the SQ gain must only exist in the presence of music. Or be a placebo effect or somesuch.
