Nice little system you have there. I'm out here in the Sonoran desert myself, just NW of Tucson... and I've been into this hobby just about as long as you have. I have a modest (humble compared to yours) A/V surround system, but audio is actually my primary focus.
That said, I wouldn't mind getting together with you sometime and checking out a Blu-Ray or two. Your room seems almost ideal for such a system.
