Roon 1.6 ... with Qobuz

[Music or sound]

I upgraded Roon as soon 1.6 got released and I am listening to Qobuz via my Innuos Zenith II and I am very happy with the sound and UI. The Zenith/Roon allows 2 different connections to my D250: USB or ethernet via AIR.It sounds little different but I have not any preference. It is great to have so much more music available through Qobuz and it is a nice Roon feature that one can see what is available on one owns selection and what is available on Qobuz. I see that quite a lot of my weird albums are not in the Qobuz catalog but obviously the reverse is much more true. Comparing the the same album from local storage or streamed via Qobuz I find the local sounds better (more resolution , better decay). I wonder wether a better ethernet cable (cat7 already) would make a difference or should I obsess about my ethernet router?
