Recently my girlfriend changed jobs and goes to bed pretty early. I now find myself watching movies at an extremely low volume so as not to wake her up. I like watching movies in my Home Theater at a loud volume, so it's killing me. I want a good headphone setup. I remember some years back, Dolby Headphone was supposed to emulate 5.1 sound in headphones. Whatever happened to that? What are my options for good surround-sound in a headphone setup? I'm kind of in the market for a new Receiver anyway.
