Topmostaudio: Inteface Converter, by itself is not revolutionary step. There ara companies which produce them for years under different names e.g. PS Audio, Linn etc and their sound quality vary.
Today, IMO, is much cheaper to produce very high quality music servers utilizing such brilliant processors as Intel "Haswell" i7 where I can sacrifice, say 1% of its power on useless activity and use 99% on music (depending, of course, how well I deal with operating system, high freq grounding noise etc etc).
If I would design similar quality "Inteface Convertot" from the scratch then to get "there" - it will cost you money which, TODAY, you will never pay. This reality forces us, in Musica Pristina, to excell (as best as we can) in music servers where we can match our technology e.g. PSU and off-the-shelf processors like Intel "Haswell"
The maojor question, I, as the end-user in search of turntable or "Interface Converter" or tube preamp ask myself - how it sounds? The particular design philosophy is much less of my concern.
Audioeng: the same answer is to you. if DAC is "garbage" (and if it has poor clocks then it is GARBAGE without going any father, don;t care about it magic tube output stage or whatever) then no music server, USB Interface etc will help it.
