I put this together to interface my single Phantom to Roon. It was by far the most stable way I’ve had the Phantom hooked up. The Dialog was a disaster for me and led me to the RPi fix. Totally took the Dialog out of the system.
I took out the RPi once I heard the Phantoms were ‘RAAT compatible’. I now get my Phantom disconnecting from the system and needing a reboot several times a day. So the RPi will probably need to go back into service until Devialet works out this stability bug.
