Who is using g Qobuz and how are you finding it? Thank you.
Bob don't pay attention to the 44K with Tidal the difference is in the kbps reading. 44K is redbook CD standard the difference it Tidal is Flac and Spotify is MP3 with never get above 320kbps. And as far as Quobuz I am sticking with Hifi as I am 16/44.1 all the way no hi-rez for me. And so far enjoying both classical and jazz on Quobuz.
Spotify (top tier) is 320 kbps

Red Book CD (16/44.1) is 1,411 kbps (44.1 * 16 * 2). So almost five times more than Spotify
Qobuz is certainly working for me. I am streaming while driving and getting CD resolution with no dropouts. The sound is excellent. The search engine is easy to use.
Next for me is developing play lists.
I have cancelled my Tidal account. 
I do think Qobuz is for music lovers!

David that's great I haven't messed around with the app really yet, using the Lightning DS app at home but looking forward to checking it out and exploring more. I haven't decided to cut Tidal yet but I may down the road we shall see.
@dbphd sorry for the delayed response.  In both cases, using the Ethernet render built into the QX5 and using the Aurender and streaming via USB, Qobuz sounds better than Tidal.  In fact, I just cancelled my Tidal membership.
