Which dac ?

If you are looking for a warmer/more organic sound see if the Bel Canto Dac 2 is still available @ Audiogon (used from a dealer for $275).

Suspect it would work well with your setup.

I used Bel Canto’s 1.0 & 1.1 with wide range single driver speakers and they both balanced well in regard resolution VS musicality.

Didn’t care for their later offerings (of 10 years ago mind you) as they became more detailed/colder.

Didn’t realize you has a Bel Canto Dac 2 for sale here (and the one I mentioned is also for sale @ A’Gon).

Curious as to what you did you not like about it (and did you use the RCA/coaxial connection)?

OK, I assume the Concerto allows USB connection.

Kind of funny that I recommended what you already purchased.

Must be a single driver mentality sort of thing.
