Good news and bad news.
Need to install the app for PC, which means another app running on music server.
Using networked Lumin U1, needs updating to Version 19 to accept Qobuz connect. Works, very quick to see Lumin and select.
The sound is not much better than Internet Radio, down soundstage, very short front to back depth. As for resolution, cymbals splash, not sharp at all. Dynamics- like radio, bad radio. Local files to the Lumin with Audirvana are top class. Far better on Android phone and Bluetooth Noise free Headphones (Sony Xperia 1 VI, Sony WXM1000XM5).
Good for background music, provided Qobuz don't force Alternative Indie down my throat EVERY TIME for new albums, My Weekly Q is a prime example, the queue forward button is used very often! You'd think after 18 months they could understand/remember my tastes in music - nah! AND reviews are in French mainly, don't Qobuz take into account the device's language settings, obviously not.
