Hi ogs, while a true reclocker may not be part of the design of the Experts an ASRC may well be. In fact the article below at the Qubuz website says Experts have a TI SRC4192 ASRC IC that upsamples all inputs to 24/192. When I look at the picture in the article it's actually a SRC4392, a higher specced ASRC.
The 24/192 sample&bit rate used to be the old official numbers spoken of in white papers, specs documents etc. I think that Devialet has later employed an additional upsampling step (to 40/384) perhaps for MAT (DSD support) or as a general improvement, in their eyes. Perhaps they've even circumvented the upsampling in the SRC4392 IC and nowadays do the upsampling inside the DSP (if that's even possible, I don't know
).

Of course the higher quality clock connected to the Mutec could help 'cleaning up' the input there locally, resulting in a higher quality output signal. As always, "garbage in, garbage out" so cleaning up as much as you can beforehand (before the actual DAC step) helps. This is also illustrated by the reports of people employing multiple reclockers in series, be it multiple Mutecs, multiple USB Regens or whatever reclocking device out there.
Nowadays I'd love to have a word clock input and I2S input as well but since it's never been part of the design I'm not sure if it could even be added afterwards by re-using a general input. I'm afraid we'd have to go back to mega buck separate DAC's and amplifiers again for that functionality.
PS. This is the second discussion in a short while where I feel it would have been nice if Devialet had some representation here on this forum to clear things up.
