while all being very good sounding units, the rme adi2 and musical paradise are at opposite ends of the spectrum:
rme is crystal clear, fast sounding, shimmery, slightly mechanical, relatively centralized, flat narrow sound stage -- probably a very honest representation of the digital signal being portrayed
otoh, musical paradise unit is ’enriched’ in the midrange and midbass, slightly rolled on the top and extreme bottom, soundstage ’expanded’ and deepened via tube output stage, more perceived coherence top to bottom
so to use again the very apt analogy by john darko the reviewer -- ’skim milk vs full fat’
schiit gungnir mb is smack in the middle in terms of tonality but with nice imaging (imaging is the rme’s achilles heel imo, not an issue for hp listeners of course)... gungnir issue which led me to move on is there is prominent relay clicking between tracks, if you change source or different bitrates, irritated me
hope this helps those trying to make a choice
