Interesting comments on the Prophet-6. Have you tried the Prophet '08? I'm just curious, because the sound of the Prophet 600 always reminds of the Prophet '08.
I've never played a Prophet 600 either, but many of the videos I've heard sound excellent - and by that, I mean the character of the instrument, and not necessarily the high audio quality of the recording. It's funny how the former still comes through, in spite of the latter. I like the directness and simplicity of the control panel. Just the fundamentals.
There's quite a difference between the Jupiter 6 and the P600, isn't there? At least with the P600 you can get the Gligli update.
