> At such an event, we are in a natural sound field and can readily perceive that the sounds of different instruments come from different locations Huh? Maybe for orchestral music or small house shows without a centralized PA. Any other concert is going to have the musicians mic'd or going line-in to the mixing board and then played in stereo through massive speaker stacks. At a concert with more than 1,000 people you're not hearing any of the onstage sound.
