I'm not sure I can add anything that hasn't been said. However, I'm running BIAB from a Dell Studio XPS laptop (7500 drive speed) straight into a sound system, along with electric guitar and vocals. I like my Bose Model II, but it's not stereo (for the benefit of the tracks). Sometimes, I take along two Roland keyboard amps and use that instead. Sounds good, but the vocals and guitar sound better through the Bose. I just ordered today the new Roland BA-330 stereo amp. It's very portable and light-weight. I'm one of those who's always tinkering with the sound and looking for something different/better. By the way, for you singers, give the new Digitech Live 3 a demo. I've mentioned that before. Those vocal harmonies (tracked from the guitar chords) will really enliven your act.
