Best used dac under $2000


I am new to the world of dac's. so forgive me if I sound foolish.
It would need to have an optical digital out to pass the digital signal through to a room correction unit associated with the speakers. If sound is of question, I favor a less analytical sound and more liquid and detailed.

Thank you in advance

I've heard the Bel Canto, the Chord and Musical Fidelity dac side-by-side at a dealer. The Musical Fidelity A3 24 is the one that came home with me, FWIW. Different strokes for different folks, of course. The MF dac only shines with a great transport, however, not just any cd player will do....

Wow, that's interesting that you preferred the MF over the Bel Canto and Chord. Maybe it's because I just haven't heard enough about it. I've only had experience with the Bel Canto DAC 1.1 and my current Kora Hermes which I love.
The newer Kora is the only external dac left (In my price range) that I would really like to hear next to the others, but as it comes up for sale used rarely I doubt I'll have the chance. I'm still playing with different cd players and dacs at home before settling down, I have only a couple more left on my short list. I have been very impressed with the MF dac, but ONLY when attached to a good, dedicated transport, otherwise it's nothing special.
The people at CES told me they thought the Hermes 2 was a big step up over the one I have. Although the exterior appearance hasn't changed, the innards are supposedly completely different.
Would you guys check my thread and leave some advice:
