It seems the longer I research USB DACs, the longer my list of candidates grows, but I've got it down to four, at the moment, all under US $1500.
I'm wondering if anyone has an opinion regarding these possibilities:
1) Ciúnas USB to SPDIF Converter + Metrum Octave (the original, which lacks USB input, at roughly US $510 + US $849 = US $1359, currently)
2) Ciúnas DAC (at US $729, currently)
3) Metrum Octave MkII (at US $1230, currently)
4) Reconnessence Concero (at US $599, currently)
That's quite a spread in cost and the Reconnessence Concero or Ciúnas DAC could offer the most bang for the buck, but which combination "sounds best" and why, independent of cost (for use with a neutral amp and LCD-2 rev. 1 (or eventually, LCD-3)?
