I have used both the 740 and the 9000 professionaly. Of course there is a difference, but not to the audience. Nobody noticed. The main drawback on the 740 to me was that the Vocal input wasn't as good, and the Harmonizer can not be muted by simply assigning a footswitch to that function.
I found a work-around by using Registration memories, but never was really satisfied with the vocal sound.
