nfaguys,
Yes the Behringer is balanced in and out, and 24/96 processing. Very clean, no artifacts that I can hear.
I do hate the fact that the signal gets converted so many times, I wish the 990 had a digital out processor loop, process it in digital, then go back into the 990 and finally converted to analog. I also have a DEQ2496 which I can use all in the digital domain and its great, but I have to use that for other duties no related to HT.

At any rate the behringer does not add any noise, but is susceptible to ground loops, and the dreaded 60 hz hum can show up. But with good grounding and ground lifting if necessary, it can be eliminated. So far I really like it. i plan on using it with RoomEQ wizard this weekend to teek my system some more.
