Clay. I have a DA7 also. Had it for like 10-12 years. I quite like the board.
I think the convertors sound great. But, then, I don't really have a comparison to judge by.
That said, I do just use it as pretty much a patch bay come to think of it.
I used to run stems thru it for mixdown via adat but haven't done that much anymore mostly because of the hassle of recalling mixes.
I recently got 16 faders to control 16 in Sonar which was pretty cool but haven't revisited that.
The wow factor has worn off I guess:)
I'm really not clear on what you are asking though??
