The Digi 002 would be geatly improved with a good external clock source. I use an 8 channel AD ran into the adat interface of the Digi 002 and sync the Digi 002 to the adat interface. It made a great improvement. I'm using a Ramsa ad96 convertor. I don't know how good the ad is in the focusrite but its a good chance its better than using the digi's internal clock.
