Ah, well that makes sense, considering that the other two flagships are much more digital. Fixed.

Before today I knew almost nothing about Studio Electronics except that the SDE-1 is a pretty good replacement for a Minimoog. I guess all the filters on the ATC-Xi could bring out a lot of range- but meh. The new Boomstars are $500 less and sound better.
@mantiwhore- while I may lose sleep over not completing the list, I have a responsibility to all the analog rookies not to steer them towards anything less than a respectable synthesizer!
