I don't remember offhand but there was a thread on this several months ago where a number of us posted our typical values for quiet listening, "serious" music, "kick ass loud music", "typical" movies and "show off the system" movies.

With a few exceptions, they were all under 100 dB. I think I only went over 100 dB for "kick ass loud music" and "show off the system movies". A few people consistently run at 100-115 dB but you can guess that from their systems
