Didn't say that, I just mentioned it for completeness because most people aren't that familiar with the differences between the products.
Furthermore, since when isnt SNR some measurement of sound quality. Anyway its a parameter of conversion quality.
Is so high nowadays, these differences can not be perceived.
And yes, I have also asked myself what the decisive criteria are for a very good and above all spatial / three-dimensional sound with good localization of voices and instruments.
It is m.E. not SNR, that is only a "side effect" of increasingly high-quality components.
I suspect it has more to do with the DAC, the correct control of the DAC chip and with the timing / board layout. But that's just a guess.
Of course, the speakers, all components in the signal chain are also important and it is certainly not bad that in the RME design the clock is refreshed again and jitter is taken out and ultimately converted with the local clock D/A.
But a few dB SNR do not make the cabbage fat, you do not hear that anyway. This is the noise to voltage ratio. Do you hear any noise there ? Well, I don't. No matter how the volume is set.
In the ADI-2 range of products you have the full implementation of "femtosecond"(FS) jitter supression tech, while the UFXII manual mentions "steadyclock". I dont know if they are the same or different iterations.
FS clock has not been implemented to all RME devices yet.
It was newly introduced with the ADI-2 DAC FS, then it followed for the Pro FS and the other products got it.
Babyface Pro FS, AIO Pro, UCX II.
But the common sense is so far, that you get measurable higher SNR but that this is not audible.
