It's a Lumin D1 Olan. The sound quality is extremely good. SQ is pretty much what Lumin are about. Sounds great straight into an amp, even better through the Meitner though obviously. You can stream Tidal and Quobuz but no Spotify due to it not being high res yet which is a bit of a shame although you can stream Spotify via Airplay through the Lumin. The app is good on IOS but crap with Android. I have a Bluesound node too. The Lumin has far superior SQ but the Bluesound gives you access to pretty much every streaming service. I think there is even some sort of Roon integration due soon if not already and it's a quarter of the price.
Just to add that yes you can do internet radio through the D1 but that's not something I have bothered with. I think you need to sign up to some 3rd party service though. If you want to know anything about the Lumin streamer ask on Audioshark. One of the designers posts there regularly in the Lumin section.
