I believe I understand sound, although I really don't understand music, and I am more of a movie buff than a music lover myself, so I attached my video sound to my stereo about as soon as I moved out from my parents house in 1987. Already in my childhood home the "TV-room" was separate from the livingroom, and I have kept it like that since, except for a few years, when I lived alone. In the late 90's I started experimenting with surround, and now since several years there has been no regular TV in our house, only a small home cinema (video projector and full 5.1 sound) for serious watching, and computer screens for news etc.
Incidentally, I noticed today that the most cost effective way to improve the fidelity of your system (especially the high registry) might be dewaxing your ears
