I didn't find much of a difference between the 740 and the 2000 except ergonomically and chose the 740 because it was easier to use (and a bit cheaper). They both sound much the same to me. I would have preferred the 9000 (which really is much better) but didn't have the cash, and would still get one instead of the Tyros as it has more features and internal speakers. It all boils down to personal taste in the end however, so pick the one you like best.
