It's rather nice to see high-res files stream without an issue to the swarm of raspberry PIs I have, can't wait for the BDP to support this.
It's probably too early to judge, but the on the iPhone, there is a difference in sound, mostly noticed Qobuz is louder. Playback on the raspberry pi seems similar though and the app controlling both tidal and qobuz seems snappy on searches and usability, kinda fun to build a playlist between both services and local files.
One huge advantage with Qobuz over Tidal and the other download services, I can actually find high-res music for more current artists.
