Qobuz vs idagio vs primaphonic

with Primephonic the transition from the middle movement to the final movement of Beethoven’s Piano Concerto No. 5 is accomplished the way Beethoven intended -- with no interruption. Qobuz, sorry to say, takes an axe to the transition, inserting an annoying audio dropout.

This is known as gapless playback — the ability to play continuously from one track to the next seamlessly without interruption. The Qobuz app has bugs and performance issues that still need to be fixed. Gapless playback on Qobuz works well on my newer Mac computer but there are brief gaps between tracks when playing Qobuz on my old Windows laptop. I don’t have the issue with Spotify or Tidal.

I’m pretty sure that none of the streaming services have complete operas.

I subscribe to Spotify, Tidal, and Qobuz. All three have a huge number of complete operas. The ultimate example: they all have many versions of the complete Wagner Ring cycle (Solti, Levine, Furtwangler, etc), each clocking in at 14-15 hours. It’s shocking if classical oriented Primephonic doesn’t offer complete operas. The music labels certainly make them available to the streaming services.

Is airplay lossless via bluetooth connection from my iPhone to aurender ?

Airplay streams over WiFi (not Bluetooth), at 16-bit/44.1kHz lossless. If the audio source has a different resolution, it will be resampled to 16/44.1 before transmission.
