Given that this thread is 9 pages long, I'm not sure if this has been mentioned yet or not, but I've really been enjoying the Mugzy's Move CD. It's big band music and was mentioned in the Audioholics review of the Axiom system.

Apparently it is one they use for demoing audio systems they review. I picked it up and find that it really shows off all of the best qualities of the Axioms. Admittedly, it's a far cry from chamber music, but IMHO it makes for very enjoyable listening if you enjoy Big Band music. \:\)
