AirPlay question - Octavio Stream using as airplay device

Hello,
the Octavio Stream network player is using AirPlay 2 as one of its integrated technologies. So I can see the Stream under Roon as Airplay device. My question is, if I use the Octavio within Roon which resolution I will get? AAC (Airplay 2) or CD quality 16/44.1 when I stream my library files, Qobuz or Tidal ???
Thank you

Roon sends out 44.1/16 over Airplay. Your signal path will show what is going on.

Both my Octavio AMP and WiiM Mini play CD quality through AirPlay.

thank you, so it doesn’t matter that the Octavio is an AirPlay 2 device.

Not in this case no. As Roon uses the original AirPlay and AirPlay 2 is backwards compatible.
The original AirPlay supported up to 16 bits/44.1 kHz. (Audio CD quality). For whatever reason Apple decided to limit AirPlay 2 to 256 kb AAC.

thank you. all clear now, any sound differences between Octavio amp as streaming device and WiiM Mini?

Normally yes. However as I’ve connected the WiiM Mini through its optical output to the Octavio AMP the Octavio’s DAC does all the work. So in my case they sound the same.

The Mini’s DAC doesn’t sound as good on its own if I am using the analog output.
