Your reaction to replies don’t make sense. People are simply responding to what you wrote, these were your words. You describe the sound as “incredible “ . So in your opinion the sonic performance is awesome/outstanding:phenomenal etc. If so, then the supplied SMPS is functioning very well.
No one suggested that further sonic improvement is not possible with a LPS upgrade, not anyone. Chord it seems uses a good quality SMPS with their DACs. The higher level Dave uses a SMPS and owners are apparently very happy with them. So utilizing a SMPS wall wart doesn’t imply poor quality. Particularly if it’s in a component described as incredible. Did you perhaps choose this term inappropriately?
