The Hi-res tracks are labeled: Hi-Res-Lossless!

Note that lossy Apple Music and Spotify have always been 44.1kHz sample rate…
So the Lossless label is for CD quality (1411 kilobits per second) at 16 bit 44.1kHz and also for 24bit/44.kHz and 24bit/48kHz.
There are screenshots in posts above of the hi-res label (for higher than 48kHz sample rate).
There’s heaps of stuff on Apple support pages

Thank you! So its like a “upscaling” from MacOS? But we can’t change the method like in Roon or Aurivana?
Hmmm… Beatles are Lossless. And Dolby Atmos.
Tried Abbey Road. At first ear, Come Together in Dolby on AirPods Max does not sound very convincing compared to non-Dolby Lossless. A rather thin-voiced Lennon in a lot of swirling space. First impressions though – subject to change.
No what I meant is if you are playing a 24/96kHz ALAC track, you can manually select 96kHz sample rate in Audio MIDI, so you don’t have any resampling.
So this is to avoid resampling before your DAC (if you want to avoid)… until Apple sorts this out, with automatic sample rate switching.
I guess you can also using Audio MIDI to upsample to a higher rate if you want but I’ve never done that.
My comment was more about using Audio MIDI to manually match sample rate.
I’ve found this with some tracks, they don’t sound as good as stereo.
Tracks like Black Skinhead (the best I’ve found so far), Tour De France and Riders on the Storm sound much better at least to me.
So, can you stream from Apple Music in the highest resolution up to 192 to an end point (Ethernet or Wifi) or does a computer have to be attached to a DAC by USB?
Yeah, I know. But if I refuse to switch with every song, what does it mean setting the DAC to 192 or even 768 fixed in my case? Is there a difference between “resampling” and “upscaling”?
I use Audirvana to upsample my Delta-Sigma Dacs to “the max”, is this the same thing via MDI-settings?
AM does not support UPNP or RAAT… so I guess you have to stick with a USB-DAC. Airplay does not support Hi-Res either afaik.
This is the source… can you check on the endpoint in the KEF App? Airplay is limited to Redbook imho.
Ah ok.
Sounds like more of a mobile / desktop music solution then rather than something that would compete with Roon.
Resampling can either be going up to higher sample rate than source content (upsampling) or going down to lower sample rate (downsampling).
As I mentioned above:

Just as a matter of interest - are all or most of you who are posting on this thread going to abandon Roon, Qobuz and Tidal and move lock stock and barrel to Apple Music, or will you be using Apple Music as an alternative for maybe mobile use?
You can set to whatever your DAC supports, if you want.
Chord DAVE DAC is a delta-sigma DAC also.
Part of the nice price you pay for that DAC is Rob Watts upsampling (his WTA algorithm).
You can use Audio MIDI to upsample all your Apple Music to PCM768kHz with DAVE but just because you can, doesn’t mean you should with that DAC example…
But you can ! 
I was using my iPhone over AirPlay straight to the Kefs. Tap on the lossless logo and it will give you format.
I already own it, thanks. It works for local files, not streaming.
I’m trying Marvis Pro + Apple Music to see how it compares to Roon.
No rush to switch as it’s on a free trial for 3 months. It will be nice to have the mobile app.
From what I can see AirPlay Max’s out at 24/96khz.
Currently playing this album which is available in 24/192Khz but when streamed over AirPlay 24/96Khz on kefs.

I’d be really surprised if one can achieve > 48kHz from AirPlay2.
