At last! (Or so I would have thought a few months ago.)
But… I think I'll stick to their lossy offerings since I use Bluetooth Headphones mostly nowadays. There is no chance of my 59yo ears hearing any difference.
Both Apple and Amazon's lossless music made no difference to my listening pleasure.
And if I want to fool myself that I still have the hearing I had decades ago, well, then I'll listen to my ALAC files in macOS Music app. 😄
I did actually experiment one night with some good bluetooth headphones that also have an optional wired connection. When listening to good complex music, the wired connection was clearly superior and I could actually tell a difference in quality. But only with the wired connection. Not bluetooth, not the built in speakers.
The wired desk speakers sound better but to really hear the difference requires wired headphones.
