I tried Airplay from Apple TV and from iPhone, a small "lossless" logo appears on the screen when the music is playing in this format, but hard to say how the Phantom I is truly receiving it. For Atmos Music content played over HDMI was easy to identify because my receiver would display the Atmos sign and all speakers would sound, and that is really good. Now for Airplay directly to Phantom I it was hard to say on the quick test I made. I tried to turn off lossless and play the same music just to check. The lossless sounded a bit more crisp over Airplay, but could be I was just primed by the lossless logo It would be interesting to compare the same song played from other trusted lossless source and the one played from Apple Music over Airplay. Apparently Airplay 2 supports hi-res, question is if the Apple devices do recognize the Phantom as a capable device, otherwise it simply downsamples.

At least this was the info when they introduced the format. I guess someone attending the Apple WWDC 2021 (where Spatial Audio etc. is presented) might have more insight on this.(08-Jun-2021, 11:30)Hrithik0015 Wrote: How to stream hi-res music from apple music to Phantom I?

Airplay 2 supports ALAC (Apple equivalent of FLAC), so lossless, but currently limited to 16bits/44,1Khz, everything higher is downsampled by the source before transmitted.
But at least this not AAC (Apple Music not lossless codec) and it's audio degradation.

Well, my understanding of AirPlay 2 is that instead of streaming an 16bit/44,1kHz ALAC conversion of the audio file, it streams/downloads (considering the better buffer and queue) the audio files as is (as long as the format is supported and all iOS supported format seams supported, which would mean ALAC and FLAC). And that it supports various bit depths and sampling rate.
Now that Devialet has finally done the job with AirPlay 2, it would good that Deezer, Spotify and the likes do their part to enable it full potential.

Samples are only [email protected] in the current implementation.

I think the Airplay 2 announcement video and slides specs have not yet being fully implemented But there is room to grow, and probably they will implement higher res now that Apple Music is supporting it. Main problem (Sonos & Devialet have the same) is larger network bandwidth, meaning less reliability (WIFI).

Damned.
Thanks for explaining. The slides are from 2017 when iOS 11 was announced, although AirPlay 2 only made it at iOS 11.4 if my memory is OK. So that 3 to 4 years ago. I agree with wifi constraints with bigger file but the larger buffer should compensate, I don’t know how much space is available on Devialet or Sonos. On the other hand, regarding Deezer HiFi, since they are so far limited to CD quality, it only « costs » an on device conversion from FLAC to ALAC and users would benefits from a full AirPlay 2 compatibility.
