First, I'd get a house to put it all in. Then, I'd get vintage McIntosh amps all around (they're pretty!), probably a Lexicon processor, and Magnepan MG20s for all 7 positions. Sub-wise, I've never really looked a the godawful expensive stuff. Add a nice large projector... (Merry Christmas, Sushi :-)

I am the Doctor, and THIS... is my SPOON!
