No, I don’t use Qobuz, but have thought about it. May get a trial one of these days.
In terms of MConnect, I have downloaded it, and checked it out, (for the use of the Zen and Qobuz), and looks likes a direct connection between the iFi Zen and the app is pretty straight forward.
Select Qobuz, log into your account, select the iFi as the streaming source, play music without the need for AirPlay or Roon.
Why not download it and try yourself?
