How to improve Jitter issue via USB/ETHERNET ?

[Confused]

Thanks every body. So it seems jitter is not a noticeable issue in Devialet.

I saw Devialet claims when in dual mono mode it further reduce jitter, how dual mono mode can reduce jitter? Does anyone know why?

I have seen Devialet advise lower distortion figures for the dual mono units, but I have never seen Devialet quote jitter or phase noise values.  Furthermore, jitter relates to clock accuracy, and I cannot see how this would be any different between single and dual mono units.

Have you actually seen jitter figures from Devialet somewhere?  I would be fascinated to see them.
