Interesting, Greg, I didn't read that. But as I said, Digidesign gave a seminar at the last AES show in NY, explaining a bunch of Pro Tools myths. That was on of them, and while I don't remember the exact details, it was pretty convincing...and yet moot at the same time, since you can run out of headroom with plug-ins!

(I've never used the DA7 for mixing, by the way - it just sits there routing stuff.)
