Have what? While I see spatial audio and lossless icons in the AppleMusic subscription area on my iPhone, I am far from convinced the higher quality audio can be currently Airplayed to my Nova without downconverting to lossless CD quality.
We may be streaming lossless hires but Airplay may be processing that to CD quality currently.
To avoid confusion I’m referringvto Airplay from iPhone X with current iOS.
My Mac is older and running an older iTunes on High Sierra.
edit: later posts suggest we can’t even Airplay lossless CD qualuty from Apple Music yet and we get the 256kbps AAC version we used to still.
