certification of Roon RAAT starts this week

[David A]

What will the advantage of RAAT be over what I'm currently running -- Devialet Air with Roon Server running on my Antipodes?

From Hifi–swlon's post in this thread:  #12

"Zone grouping/syncing
-Roons QA & reliability. 
-Roon settings automatically optimised for the device. 
-Roon largely taking ownership so evolution over time is more on their timescales."

On the last point above, Roon say in an article in their Knowledge base:

• Support for new streaming services, file formats, DRM schemes, etc can be supported without firmware upgrade. In fact, the only reason an upgrade should be required is to fix a low-level bug, or to access more hardware functionality. This is really important. Not all partners/hardware have easy firmware update paths that can be done at home. Our acceptance of this reality has deeply influenced RAAT's design. Just as with Google's Cast devices, the majority of the business logic is delivered to the device at run-time as a script. This means that we are capable of completely re-designing the audio streaming and buffering logic without updating device firmware. This is absolutely critical, since most of the bugs + evolution in a system like this relate to networking, not audio. Other than Cast, we are unaware of another system that is this flexible.
  

RAAT also supports 32 bit 768 kHz PCM playback and multichannel playback. While Devialet only supports 24 bit 192 kHz PCM playback now, becoming Roon Ready helps Devialet simplify future development and the multichannel playback capability of RAAT may be of use in the future if Devialet make it possible to enable multichannel playback via linked Devialet devices.

Like you, I'm using an Antipodes (DS in my case) and a Devialet. I don't expect any gain in sound quality but we may see some improvements in stability (I did say "may" because Roon AIR has been very stable for me, much more stable than Devialet AIR on my Mac was). Basically, however, I'm not expecting to see big things in the short term from the Devialet becoming Roon Ready but it offers some potential benefits in the longer term and it may make it easier for Devialet to deliver some of those benefits to us.
