I think Apple Music uses AAC. But I'm pretty clueless on file formats. I do not think they stream ALAC files.
I can't find a clear answer as to what file format Amazon Unlimited Music uses but they were mp3 years ago.
Anyway, I'm still experimenting. Feel like I would need a better DAC and wireless set up to take advantage of Tidal hi-fi. Not sure how Tidal standard res compares to other streaming services.
There is a $2 per month discount on Amazon music for Prime members, which I am.
