At what volume do you typically listen?

Eleven!

5-8 out of twenty typically, 13-14 out of twenty preferred if I can get away with it without the wife getting upset.

My smaller 12X12 room where the equipment is was built with insulation in the ceiling and interior walls in addition to normal exterior walls and has a solid wood door (compared to hollow normally) so that I would have a place where I can crank things essentially at leisure without disturbing others in the house, even late at light.

In my big room and in my wife's sunroom in particular, I have to be a bit more "controlled".

75-85db is about right. If really rocking I may hit peaks over 85 but to be honest that is pretty damn loud. For those of you have have an iphone there is a good and cheap SPL meter app you can dowload to give you an idea of your listening levels.

The volume dial is near meaningless as a measure of loud. Some setups are deafening at 9 PM others are still fairly quiet at 3AM...however if you like playing with your knobs who am I to criticize.

My normal listening is done between 75 sand 85db , but occasionally buzz it up to 100db , or better .
