Tearin' up, yep! Exactly what you'd expect from a 2600 in the right hands. I had much the same reaction to my "Xmas Tree" model...the form factor kept reminding me that this was a NEW synth, but I swear that it sounds like you'd expect a pretty new "Orange" to sound back at the end of the 1970s. Until, of course, you flip the filter over to the rev.2 4012...yow!!!
Frankly, the sole problem I've had with my Behringer 2600 is that word right there: Behringer. I (and others) would feel better about this if Tribe would just find a way to get Uli to behave and not steal things (coughcoughPlaitscough).
