Hi Dean, I was a Tidal user and switched to Apple Music when they made lossless files available. I also have a Family One package that combines Storage, Apple TV+ and Apple Music for about the same as I was paying for Hi Res Tidal. I used Audirvana on a headless mac mini with Tidal and enjoyed it but since Audirvana doesn't work with streaming Apple music I have stopped using it (plus subscription model). I am using Apple music on a laptop USB direct out to a DAC. I have used an iPad directly connected and using ApplePlay 2 wirelessly, directly connected is better because it automatically swaps bit rates, using MacOS it doesn't do this which is a bit annoying and Airplay 2 I think is limited to 44.1kHz.
My comparisons at the time when I was swapping was that I couldn't accurately determine a difference between Tidal and Apple, I thought Audirvana made more difference on a Mac than the platform it was served from. As for actual hi-res files, it's so hard to do a comparison when the provenance of these files is hard to determine, I've given up and am happy with red book quality, I don't know whether my aged ears can determine the difference let alone judge between all the remastered versions as to which is best.
Having said that, on my main system it was easy to determine the steps from 256kbs to streamed 44.1 and then to locally served 44.1 file of the same recording, quite close between the last two but still there, listening in optimal conditions.
I'd go with which ever is most convenient to play back, Apple Music isn't well supported by 3rd party streaming devices. Sonos have it but it's only 256KB, you can use an Apple TV but that's limited to 48kHz and you'd need an HDMI connection, Tesla have introduced it to there media player surprisingly (not useful in the home I grant you) but that uses the Web Interface and apparently it supports hi-res but have found no way of confirming this and I am doubtful. If you have a streaming device then I'd chose Tidal for convenience, if supported but if you are happy to have a Mac or iPad as a source then Apple Music is a good alternative.
Kind Regards
