At the start of the show he said that "he always wanted to do shows like this, with very little amplification, just what we have coming out of these hand carved horns" and gave props to the guy who carved them. I couldn't tell, there were a couple of amps sitting on the stage, and like I said, it was plenty loud, couldn't really tell just how much sound those grammaphone horns were putting out. And yes there were small PA type speakers attached to the balcony rail, but were not hooked into his system. Really small, like a home theater cube speaker. I heard that on night one they were getting interference from the John Hancock Tower antennaes, which broadcasts a smooth Jazz Station, life in the high tech era I guess. Thanks again
