Well Thomas, I've always felt that unless you have an external MASTER CLOCK like the AardSync, then the DA7 should always be the master. The console is the center piece for all ins and outs of your digital studio, the HEART if you will, and everything should be in sync with it.
My choice, as you obviously know, is the AardSync. I have individual, terminated runs of 75 ohm cable going to each digital device in my room... NO LOOP THROUGHS!!! If you need more feeds, either buy the Aardvark WC distribution amp, or use 'T' conncectors and terminate the last source.
We're in the midst of this very discussion on the Sonic Solutions users mail-list with a lot of frustrated people. I've had no problems once my system was setup correctly. I've got ADATs that come in, DA-88s and run AES to my Sonic... all in happy sync.
I can guarantee, too, that once you've put a stable clock on your ProTools system, you won't believe how much better your top-end will sound.
