Phantoms not supporting anything higher than 24bits/48Khz

[quagga]

Roon RAAT gets information directly from the Devialet Operating System (DOS) and tells the truth. Everything is down sampled to 48kHz within Phantoms. @struts  has a plan to verify this https://devialetchat.com/Thread-Can-DOS-...bove-24kHz

Unfortunately, it seems you are right, everything is down to 48kHz  within the speaker whatever the source and connection is.

The point of such specs, as Reactor 900's following for example, is like the Phantom telling us "I will do you a favor and not ask for low-res music files, jut give me your hi-res and I can lower it to 48kHz for you": 

• On-board Texas Instruments PCM1796 24-bit / 192 kHz DAC
  

Same with the inputs. Just a convenience, ensuring it will also play the high-res files, at low res. 

Funny.
