Pathetic but I have got the same problem with G1. No matter what I do Auralic does not see the dac’s (RT-Project DAC One; 2 gears : solid state and vacuum tube versions). And without any issue G1 sees r-DAC, probably cuz its (r-DAC’s) USB-bus is supplied from the device. My NOT very humble opinion is: to Auralic Co- resolve this please and do not shift the responsibility onto end users.
Anyway the SQ is more than good
Best regards jj
