RAAT vs Upnp - Hrithik0015 - 02-Feb-2021
Now that the phantoms are roon ready, is it worth it to use roon? I currently use audirvana and use upnp to stream to gold phantoms. Is there a difference in quality between upnp and RAAT?

A bit off topic, but could you please try streaming some 24/192 material over UPnP if you are on DOS2 and report back?

When I tested in Audirvana today via UPNP it plays a 24/192 track as 24/96 to my silver phantoms

Same! Just tried it. Roon plays 24/192 as 24/48.

@TechGuy and @Hrithik0015
Thanks a lot!
RAAT vs Upnp - Bean86 - 02-Feb-2021
I just updated to 1.12.3
Out of the box the Devialet are setup in Roon only as 'Renderer' and Roon down samples the output to 24/48kHz.
Whent into the advanced settings of the Speakers within Roon and switched the Phantoms to 'decoder and render' now no down sampling is apparent.
EDIT: what the Phantom decoder samples the input too I don't know.
EDIT2: now I only have to wait for Roon to support Tidal Family accounts (tie the account to the profile rather than the core - the request is only pending 4+ years now)
Fortunately I work in IT so I've set up 2 cores on my server as a work around for now (wife's core set as default and I switch when I need it myself)
I don't have equipment to test what actually exits the Speaker

RE: RAAT vs Upnp - The source - 02-Feb-2021
My question is if bit vs Hz is the important thing here.
Like 24/96.48 vs 24/192
What about the protocol itself?
Upnp vs RAAT.
They both have the same rating 24/96.48
So what drive me to use roon vs lets say Audirvana ?

Last time I looked into Audirvana was 1-2 years ago and I had issues on my admittedly complex home network.
Roon worked for me out of the box and I can control all music to all my different speakers from one central location. The last part is also true for Audirvana I think (as said I didn't test it for too long)

When the Phantom MQA capability is set to 'Renderer'
- Roon performs first unfold, I.e. 48kHz to 96kHz and MQA rendering information is retained
- Phantom down samples to 48kHz
When the Phantom MQA capability is set to 'Decoder and Renderer'
- Roon performs no re-sampling, I.e. the 48kHz audio is passed to Phantom
- Phantom performs no re-sampling
Phantom has no MQA capability and to avoid confusion, should perhaps be set to 'No MQA support'.
- Roon performs first unfold, but importantly does not retain any MQA rendering information
- Phantom down samples to 48kHz

Set to Renderer and turn off the enable MQA core decoder under advanced setting. It won't downsample to 48khz
