Qobuz vs Airplay

@mahler123, look at your Apple iPhone or iPad, whichever one you're using for comparisons. Under settings, there are 3-4 levels of sound quality.. You will see the quality and various data transmission methods - cellular, 5G, WiFi, and hardwired to DAC. Hi-Res Lossless 24-bit/192kHz is not by default. When you did your comparisons, what were your settings?  If you used defaults, you're not alone, including me, in simply turning on the phone and starting to play without checking its settings. 

You can not use AirPlay with Hi-Res files. Apple Music requires a couple of extra steps to access Hi-Res. 

As stated earlier,  I use Qubuz and Tidal for my systems. 

FWIW the current Airplay2 specs max out at CD quality 16/44 which is < hi rez

Over the years, I've tried them all and Qobuz turned out to be the absolute best, then Tidal.  I stream all Qobuz, unless an album is only available on Tidal.  If you want the absolute best sound quality that any streaming service has to offer, then you'll have to go with Qobuz.  Happy listening.   

I have tried both Tidal and Qobuz using my Aurender X100L music streamer connected via USB audio to a Oppo BDP 105. I can safely say that Qobuz does sound very good (the best) but Tidal has a way better selection and a lot if not the majority of the music is available at Studio quality and the rest is CD quality sound which is a slight compromise in my opinion, Tidal is the best of both worlds ,selection/SQ. Go with Tidal. 

And YES do not Airplay anything.
