That might be correct. The optical ADAT connection can't be used for
sync?

I suspect the RME using other, better converters than the Behringer
does. This is why I expect that a completely perfect sync for the phases
might be impossible. Thomann (the dealer) claimed I'm mistaken ;), sync
is possible.

Anyway, I'll read about ADAT and sync. ADAT is new for me, since in the
earlier days it was used by semi-professional studios only, I never was
in a professional studio or home recording studio using ADAT. I guess
today it's more common than it was 'some' years ago.

I thought ADAT is similar to S/PDIF and usually S/PDIF is used to sync
identical elCheapo cards when using them as one virtual card, something
I never tried to do with my Terratec cards, instead I bought the RME.
