Bummer.
The Roonbridge endpoint like Danny talked about works very well with Roon. I have ethernet to the Roonbridge and SPDIF out to the Phantom. That allowed me to smash my Dialog to pieces with a sledgehammer (which gave me much joy). It works better than it ever had before. It shows up as the Ropieee device, not the Phantom.
To make it wireless you could probably just put a wireless access point in front of the whole thing.
Thanks for the update. It’s helpful to learn how all these things work, and sometimes don’t work.
