Hi-Res Audio (High-definition audio or HD audio) is a term for audio files with greater than 44.1 kHz sample rate or higher than 16-bit audio bit depth. It commonly refers to 96 or 192 kHz sample rates. Research into high resolution audio began in the late 1980's and high resolution audio content started to become available on the consumer market in 1996.

Sonos is an American developer and manufacturer of audio products best known for its multi-room audio products. It also offers the AMP to drive unpowered speaker pairs and the PORT to link a Sonos system to conventional audio equipment such as amplifiers and CD players.

Sonos now supports higher audio quality with a Qubuz Studio Premier subscription:
+

Qobuz offers digital music streaming in CD quality (FLAC 16-bit/44.1 kHz) and hi-res quality (FLAC up to 24bit/192khz). 
+

For titles who are not available on Qobuz I use Tidal (with MQA files support).
Tidal HiFi (CD quality – FLAC 16-Bit/44.1 kHz – and MQA – typically 
lossy 24-bit/96 kHz).

Apple upgraded its entire streaming music catalog to lossless audio using the ALAC (Apple Lossless Audio Codec) format. ALAC is a lossless compression format that lets Apple make smaller file sizes without impacting the integrity of the original audio recording.

Lossless means that after compression and then decompression, the audio that you're hearing is identical to the audio as it was recorded by the artist, preserving the texture, detail, and sound that went into the music when it was created.

With lossless audio, ‌Apple Music‌ subscribers can listen to songs exactly as the artists recorded them in the studio and intended them to be heard, at no extra costs.

It will not work (for now) with Roon, but fingers crossed maybe in the near future.
