Hi
I've recently moved over to Roon as my music player and have been using this as the source for the VANA player via DietPi configured as a Roon endpoint as my second system.
However I have been using Ropieee (http://www.ropieee.org/) as my current Roon endpoint (Raspberry Pi 2 with HifiBerry DIGI+ Pro) in my main system into which I plan to place the DigiOne.
Ropieee lists the DigiOne as an available board so hoping it is supported and ready to go.
I've just received a Raspberry Pi 3 (bought from Bourneendboy aka Bill) which I've set up with Ropieee ready to take the DigiOne when it arrives.
This will be fed into an M2Tech Young DAC via either BNC or RCA.
Cheers
Dave
