NObby,
Since the EQ and effects are so good in the 2000, maybe yoiu just need a stereo power amp .... like a rack mound unit. Peavey makes a nice one that only takes up 1 space and puts out over 200watts. The kb has enough guts to go straight into a power amp input without a mixer, but if you want more versitility .... get a two space rack, like the SKB and fill it with an amp and a single space mixer .....BTW I have a Rolls for sale if you can't find one.
