The three loudest presentations I've heard were at your two houses and at a Bang&Olefsen. Their $45K rig was pretty loud. Next comes Paradigm puppy.
Rick's did get good and loud...The sub being like +10db didn't hurt either!
Walter, If you hear someone knocking at your door to the beat of what your playing it's just me looking for concert like sound and some high quality food!
(like you can hear someone knocking at your door...Do you have a light that is triggered by a door bell?
