Denon support on Roon Ready certification ETA:
We do not have any kind of official date or eta on this requested feature.
All I can say is that we are looking into it and may have a solution for you in the not too distant future.
Also this post on ASR forum sounds interesting especially features below:
- first-ever multichannel-certified Roon endpoint/multichannel streaming support
- idea of Dolby Atmos support via Tidal is being considered
