New at Qobuz - no HiRes sound


Perhaps a stupid question: I am currently trying Qobuz Hi-Res coming from Tidal. I am using a node2 with external DAC Mark Levinson 30.5
I am controlling the node2 with my iPad using the BluOS controller.
Since starting Qobuz I noticed that some albums labelled "Hi-Res" do not play. I can play them using the Qobuz App on my iPad, though.

Questions:

1. I was told for Tidal when not using the BluOS app but the Tidal App the music quality is limited to Bluetooth level. Is that correct for Qobuz too? At least that would explain why I can listen to these albums via the Qobuz App.

2. I never experienced problems with Hi-Res files on Tidal. Do I need to change settings (now at 96, not 192) via WiFi?

3. My Mark Levinson DAC is older technology. Could that be the reason? But then again: Never had an issue with Tidal.

Any help is greatly appreciated.

Dunno.  No Qobuz problems on 5 streamers including BluSound.
Android.
Try deleting data in app.
You have to set the maximum streaming rate in the Qobuz desktop app.  It will default to CD rate. While your doing that you need to shutdown BluOs and the iPad and when finished re-boot.
Unless there has been some update to your Mark Levinson 30.5 DAC you don’t want to be sending it anything other than 32kHz, 44.1kHz, 48kHz, 88.2kHz or 96kHz data...

My guess is that Tidal had never sent above 96kHz if that...

BTW, as I understand it, Tidal HiFi/HiRez is 44.1kHz and MQA fully unfolded could be up to 96kHz in an MQA compliant DAC...
