Nice write up, Don!

It looks like your info for music reproduction kinda “morphed” into movie/home theater reproduction, though. The fact is, two speakers do a fine job of reproducing music (although I expect three would be better, as the Bell techs found), because it mimics a live performance, where the players are always in front of the audience. However, extra speakers for music reproduction are useful for adding ambience and/or mimicking a venue’s acoustical signature. The music DSP effects my Yamaha has do this, and it can be very gratifying.
