My DAC recommendations are
Bifrost 2 - best value, very good tone/timbre, extension
Gungnir Multibit - lively, jumpy, emphasizes transients, more punch and slam as BF2 but tonally colder.
Matrix X-Sabre Pro - most neutral, very clear, images rather flat
V850 - no nonsense DAC, politer than the rest, more rounded than most, no digititus at all
Convert-2 - for the crazy and bold, very hardhitting and jumpy, very exciting and good tone, kinda polished like Ubisoft's Antialiasing, not the very best in microdetails but still very good, 19" format and not the best build/design.
Yggdrasil Analog 2 - amazing tone and timbre, hard hitting bass, warmer than Gungnir but still great attack
Never heard Hugo 2 or Qutest.
