Seriously, the moment you learn a few things about running sound, you'll be forever disappointed.
My favorite two things:
1) soundman has no hearing above 4KHz, so the treble sounds like an icepick being jammed repeatedly into your ear hole.
2) Put subs at either side of the stage, so you're either inundated with bass, or can't hear it (comb filter-o-rama)
Put both of those together, and now you will seek a nice warm bath, and a single edged razor.
