What I have is more like a souped-up living room, rather than a dedicated home theater.
I'm watching on a 50" Panasonic P50G10, connected to a Panasonic DMP-BD80 Blu-ray player. My sound: Yamaha RX-V663 with Klipsch Quartet 5.1 sound.
Unfortunately, due to my living room layout, I sit about 12 feet from the screen, though sometimes (when the wife's not around) I pull up the sofa to about 6 feet.
