I have a Lumin T2 that is roon endpoint enabled and I use and like Roon. The lumin app is very good, stable and intuitive but it does not provide the metadata depth the lumin does. you may with to consider a free roon trial and make your own decision.
Lumin and roon
Purchased the lumin D1 streamer. Has any lumin owners out there compared the lumin compatible navigation apps with roon? I read in a 2016 forum that roons metadata is not good...yet roon has had a lot of praise elsewhere. So, is your experience with lumin the best with roon?
