I have a Monnriver 404 Ref for my 2nd system and was thinking of installing a DAC module. It would be useless to me without Roon. Is the DAC unit made by a Roon ready partner, or any plan to include that unit?
It’s the manufacturers responsibility to make device’s Roon Ready, not Roons, but the Moonriver 404 module looks like a DAC module and not a streamer.
You have plenty of options of streamers and streaming DACs that would outputs to RCA, USB or SPDIF that you could look at.
Many user’s here choose to use a Raspberry Pi (running Ropieee) to USB for a low cost and high quality USB output to DAC, but these day’s there many pre built units on the market that would suit your needs if you look at this page
