Just listening to Seychelles on Qobuz… sounds very good. The volume is lower… not uncommon on recordings mastered to sound better, the don’t compress or compress as much. Turn up the volume. Much of classical will have a “lower volume”.
I have done extensive testing of Qobuz vs Tidal… between sound quality and availability of high resolution music Qobuz wins hands down. They are both incredibly reliable. If you have trouble with them look at your streamer.
Dropouts on Tidal or Qobuz are almost a problem of the streamer… not the service. I listen hundreds of hours a year and maybe have drop outs once a year. A good streamer buffers you from the network. Services other than these two are much inferior.
