Only if used by audiophiles...

Thank you MC!

I'll use unshielded ethernet cables then, just in case

Do you mean that there is like 4 transformers on all ethernet ports? Cool! What about eventual shielding?

I agree that ADAT, and all optical transmission, is ground loop free. But if ethernet is transformer isolated, it should be just as ground loop free the way I see it, or why shouldn’t it?

Since ethernet is always run over a transformer, there's very little potential for ground loops. ADAT is even better in that respect.

Hi,

Does anyone know how AVB (and specifically RME AVB) handles ground?

It there a potential risk of ground loops?

I know that there are both shielded and un-shielded cables.
