I spent the weekend debating selling off everything and picking up a 722. Came damn close to doing it, mainly out of the convenience of a one box solution. But I downloaded some straight mic in 722 sources and did some reading (and reading between the lines) about the 722. Finally decided to stick with my beloved V3 and hope for good things with the M-Audio Flash tracker. I also heard that low end coloration, which I didn't care for. That combined with Doug's comments, Lil Kim's comments, and Brian Skalinder's comments (who seems to own the same pair of ears as me) made me think that I might not be happy running the 722 as a one box solution, so I'd rather have V3>flash tracker than V2>722.
But another thing I didn't like was that it appeared to only have 12db, 18db, and 24db HPF rolloff slopes. That is what is listed on the SD website on the specs of the 722 and the manual seemed to indicate it as well, though it was very unclear from the writing. Good to hear that a 6db slope is available -- thanks for that info Nick. That was almost the deal breaker for me thinking that I wouldn't have the option of a good HPF available, but I think I'm skipping the 722 anyway at this point. If the Flash tracker doesn't live up to its promise, maybe I'll revisit the 722 decision again though.
