I dug into this issue before, but have not found a useful answer. I have set MC20 to bitstream and through USB it works fine (DAC has native DSD support). I also use another DAC in my network through DLNA. Does bitstream also work via the DLNA (i.e. ethernet). How can I check whether the other DAC has native DSD as input. Most DAC's I know which support DLNA and notoriously vague on what happen in DLNA mode.
