After investigating, I can see that Ethernet/Roon may well be the wave of the near future for audiophiles.
It isn't for me. I compared Roon to DLNA/UPnP on the same hardware platform and DLNA sounded better. It was the Roon software compared to Linn Kinsky/Minimserver. This is why I don't offer a Roon-Ready product. I offer a better sounding DLNA product. When they can make a better sounding playback software, I will consider Roon.
You can still stream pretty much anything using DLNA.
