Roon supports Devialet AIR

[Hifi_swlon]

Roon Advanced Audio Transport (RAAT) reads to me like Roon have set a protocol and whoever builds a RAAT ready device just has to comply with that protocol. I really wonder how much freedom a designer actually has implementing RAAT.

Not so much 'freedom in implementing', more a set of standards for 'how' it's implemented - i.e. thoroughly tested and verified as reliable, and supporting all the controls etc that RoonReady mandates (power on/off, input auto selection, volume controls, reporting back sample rates, etc). Thankfully, random pops and crackles aren’t part of the RAAT spec, so if it’s happening within the underlying Devialet code it will finally need fixing

Pretty sure it will also be tested grouped with other RAAT devices to make sure playback sync is all working properly.

And it will have to sound equal to AIR - i.e. it can't just be shoehorned in, it has to be optimised to be the best it can be.
