So this is the second best DAC I've heard. The first is an order of magnitude more expensive MSB.
This thing plays way better than my own Accuphase DP750.
And I really didn't expect that.
It excels with HQPlayer on DSD 256-512 via USB, but is also excellent on 44.1/16 via coax.
It is good to play Holoaudio for a few days, the sound improves.
