Apple Music is high res, but like Tidal and I think Qobuz, their library ranges from 16/44 to 24/192.

Honestly I have to really try hard to hear the difference between 16/44 and anything higher, and 16/44 is certainly sufficient. I grew my audiophile ears on CDs, so that's my baseline. I can hear the difference between 16/44 and many Spotify 320kbps tracks. Unacceptable for anything but background music. If Spotify ever gets off its fat ass and releases its high res tier, I'll probably switch to that because I already have a Spotify family account for my wife and kids, and I think it's "radio" functionality is better than Tidal's.
