I understand that Donny, but if I were sitting out in the audience would a pair of CM30 sound pretty much like the BA330? I guess what I'm really asking is if it has that distinctive Roland sound, which is much different than Peavey, Mackie, Bose etc.?

Not to color your answer, but I liked the CM30 until I tried the Compact. The sound was much smoother. For me, all the Roland amps I've ever played are a little harsh, even rawer than Peavey. Mackie seemed an acceptable middle ground but I didn't find anything I wanted to lug around. And as has been discussed, it is one portable, stereo unit. Stereo is not a biggie for me, but I concede it is a big selling point.
