Thanks for the pointers. I have my surround sound in the living room downstairs and I have a large triple window in that room, with a sliding glass door int the dining room slightly behind that. I'm beginning to think that most of the sound is leaking through both of those. I'm going to try some really thick curtains and see if that helps. It's really only the neighbors whose bedroom faces my house.
As far as befriending my neighbors goes we're on good terms but I really just don't like them enough to want to hang out. I'm really just wanting to be respectful while still being able to give myself an audio headache.
One curious thing I found out last night with the sibilance thing is that if I switch my reciever to 6ohms I don't hear the hissing at all when I watch TV. Strange but true. I've been told this can't hurt the speakers. Hopefully this is true, because the hissing was driving me crazy.
