@ssmaudio Roon doesn't actually deliver audio to your DAC, unless the Roon Core (your Mac) is connected to your DAC via a USB audio connection.
In all other cases you still need a Roon "receiver" for the Roon Core to send the music data to, and that receiver then either renders it as analog audio if it is a DAC, or the receiver outputs it as digital audio to your DAC.
So when you wrote "I’ll connect to the streamer through a Roon core running on my Mac" I think we all assumed that meant connecting to a Roon Ready receiver that is on the same network as your Mac.
