One of my "pet peeves" is when we go to a venue and the sound reinforcement engineers have the volume so high, that the room won't accommodate it. You see someone singing into a mike, but can't hear them, you see someone playing a horn into a mike, but you can't hear that either, etc.
I must admit, when some of my music buddies come over to audition my audio system, they DO play the music at a volume level a bit higher than I find "comfortable", but not at the level you find at many live performances.
