Pretty close.

we don't have kids, so gotta spend the cash on ourselves.
It came down to getting fed up with inconsiderate people at the public theaters.
Nice theater!
In some ways, I ended up building my theater BECAUSE I have a kid. This is my daughter, sleeping peacefully:
That's her as seen on my night vision camera, which allows me to monitor her sleeping, as most of her seizures occur at night. And while my sweet daughter is sleeping, Daddy is seen here about to go on a homicidal rampage on Grand Theft Auto 4 on the big screen:
Lousy pic of the front of my messy Bartcave:
Pic of the rear of my narrow room. I think there's a Sadowsky case back there somewhere:
It's a 92" screen (diag), since the room is so narrow, but it's still plenty big. I put some bass shakers/transducers in the couch to supplement the sub for night viewing. Did all the design, planning, construction, installation, etc. myself, with the sole exception of the new dedicated ceiling outlet for the projector, which I had installed by a licensed professional. Movies are fantastic, sporting events are great (even found myself watching the Masters), and gaming is fun too (golf and bowling on the Wii on a big screen is a blast!).
As for speakers, I'm almost as much a fan of Paradigms as I am of Sadowsky and Bergantino.
I also think you should get out and on stage. I was in the same position you were several years ago; I mostly just played along with whatever was on TV (great practice for the ear!), and thought I'd never be good enough to gig. Then I sat in on a couple of easy songs with a friend's cover band, and that eventually turned into a sub opportunity for him, and later a permanent gig when he moved away. It's "just a cover band," but it fits my chaotic life, and I've got three gigs coming in the next two days, so I'm not lacking for stage time despite my daughter's complications. I never thought I'd be in a band, but I've now been doing it for nearly four years, and over 200 gigs. Up until five years ago, I'd never been in a real band, let alone up on stage.
Cripes, they've now even got me singing lead on some songs

, and I couldn't sing or say a single word while playing bass just a few years ago.
Sounds like you're good enough to start sitting in, and the more of that you do, the easier it becomes and the more fun you'll have. Rock on.
