Grimm MU2 here. - it’s hard to isolate the DAC specifically since it’s a combination of streamer, DAC, Preamp, but it’s clearly a step or two above my prior combination id separates, which I absolutely loved, that included a Sonnet Pasithea DAC. And for reference, I had no desire to upgrade my DAC. I love the Pasithea. My move was made to get a preamp that accepted analog inputs and simplify in the process. I didn’t expect the upgrade SQ I got.
The MU2 It is very musical, transparent, and analog sounding.
