At what volume do you typically listen?

I have a Mark Levinson 326S preamp which a friend and I call "The Venerable One". I realize that this is subjective, but until I get to 45 out of a total of 80, the speakers really begin to sing. This is just past 12:00 on the dial.

I was curious to know where others listen on the "dial". I haven't checked with my Radio Shack SPL meter, but what is a typical range at which people enjoy listening? THank you.
