What do you consider "loud" for your system?

Just curious about this. I recently listened to the SACD version of Dark Side of the Moon. My volume level was at approximately 65% of full throttle. On my handy little Radio Shack Sound Level meter, I registered and average 90db with peaks of 96db. That was using the "C" weighted setting. Basic info - I sit 10' feet from the front of the speakers. The room is 15' X 23' with 8' 6"ceiling height. It was enjoyably loud, but not ear shattering. What do others consider "loud" and at what volume level?
