Has the Roon support killed all opposition?

Probably depends on the quality of the pi digital hat, AIR is very high quality, even those people who are using other solutions (Mutec, etc.) have had to go much further than a pi to better it. The allo digi one seems to be the best pi solution and I've read that it is pretty close to AIR.

AIR is free though as long as you can get an Ethernet cable there, the only downside is zone grouping I believe which doesn't work with AIR.
