I'm currently using the fw1804 (same d/a's, no control surface, half the price) for a musical doing playback, and it rocks, solid unit. I also used it to track the promo video for the musical, it only has 4 mic preamps, but does that adat thing (see previous post) and will take 4 more unballanced inputs just fine (works nicely for us with wireless) It is a nice unit, cubase is buggy in the newest version under OSX (works fine in logic), but seems to work just fine under windows.
