I also stream Qobuz on my Aurender N20 Music Server and have no issues. I suggest you reboot your Modem, Router and ALL other devices to see if that helps.
If you songs still stop mid-play and skip to the next track, you need to do more investigation. Is this happening on all albums or just a few? What are the playing conditions when a song stops and goes to the next track? Is it 1 out of a 100 albums? What is the frequency of this stop and skip occurrence? You above post implies your Cary Audio DMS-600 is not at fault. I suggest you email QoBuz and ask them. I doubt Qobuz is causing this but you have to ask them.
Please also log out of QoBuz and sign back in.
I hope others on this Forum have some additional suggestions.
