Ethernet Switch on Devialet

[zoran_pavlovic]

if you want the best sound quality from the Expert don't use the CI board at all. An external solution like the ifi Zen Stream is much better.
I went the path with Ethernet optimization (Optical module, Etherregen, expensive LPS, expensive ethernet cables, ...) as well, but the Zen beats it easily for a fraction of the money.
More expensive external solutions are even better.

Thanks for expressing your experience. 
Anyhow, from time to time I stream over Auralic Aries Mini (with external LPS), because of Devialet can't play some Qobuz music, but Aries Mini works fine. 
So sad, since working that way, we lose the concept of an "all in one" solution.
