They're probably really good amps but I think the trend is with powered speakers. Two 10 or 12" active PA speakers could be separated for a wider stereo sound, can be rasied on a stand to get the sound over the audience, and easier to move.
I'm a fan of the new trend in linear speakers started by BOSE and now copied all over.
