Just my two cents on the bose. I heard it in a small room when I went to see Don at Ernest club and did not hear the overall quality or power of this system, but at the Jam last Sunday I heard it put through it's paces and was highly impressed, not only the clarity of the Bose with 4 keyboards, fiddle, guitar, sax and numerous singers but what seemed to be inexhaustible power. This system carried it all with no problem and did not loose it’s high quality sound.
