I have a small setup: Logic, Firebox, Eureka with digital card. I have been around the horn several times as to what my options are for a better digital connection b'tween the pre and the FB and now I am wondering if there is any reason for it. How reliable is the wordclock over the s/pdif port? Will I see any sonic improvement by adding a wordclock option (which is also much more expensive)? Additionally, I cannot slave the Eureka s/pdif to my Mac. Right now (at least with 10.3.8) it won't sync to an external clock source w/o an independant wordclock. With 10.3.9 I can't control the clock source and so I can't set my FB to slave to the Eureka. Ideas?
