What a good thread. It seems people are doing more listening than I would have guessed.
I do a lot, myself, but I have no children as of yet and am not yet married either, and am fortunate to have a girlfriend who likes music nearly as much as I do.
During the week, I generally get a couple hours on the 2nd system, in the garage, where I am building an airplane and consequently spend a of time. Usually an hour on the main system, in the living room as well. (I think it's cool so many people are using the living room for their "serious" system and building integrating it with HT as well, as I have. My 2-channel system is "no-compromis" with HT put on top of it, not "integrated" with it.)
Weekends usually mean a few hours each day in front of the main system - more when the weather makes being inside sensible.
