im all most in the same situation, i need to expand my line I\O on my Multiface I, what will be the best option :
1. buying second Multiface and connect it with ADAT + external power (i got one when i was using it with the powerbook).
2. buying Fireface 400 and connect it via firewire.
3. buying second Multiface with PCIe card and connect it with world clock cable.
option 1 will be the cheapest and 3 the most expensive, but now in thinking about the Fireface 400 as well, coz i got good deal for it. all i need is to expand my line I\O, the extra option that i will get with these cards less important,
or to get non RME card with 8 I\O and connect it with ADAT.
for all the option including the non RME card,do i need to connect them with world clock cable, or just no.3 ?
Tnx for the help.
