Sounds like you should have a good time
Seriously though, anytime you have a chance to "show off" is one of the most satisfying experiences in owning high end electronics (or at least higher than they're used to hearing). Most well done home theaters, in my mind, smoke movie theaters. If I had to choose there'd be no question of what I would use to demonstrate a home theater. The opening sequence of Lord of the Rings: The Fellowship of the Ring. Hearing Cate Blanchett open up the movie with her powerful voice is amazing when you turn the volume up (showing off your center). And then of course it has the battle sequence which really utilizes your surrounds. Then there's the moment where Sauron gets the ring cut off from him and just combusts...there is probably my favorite moment for owning a subwoofer. So you see, in my opinion, you just could ask for a better demo
