What are some candidates to really measure the abilities of the Axiom speakers, for that matter any speaker? I just got my M22/VP150/QS8 and need to let the sing. Please give me some good musical choices and/or DVD's that will test the speakers. Keep in mind I am looking for some stuff to test above 80mhz. I really want test the M22s and find out how they differ from or exceed my Energy Take2, Boston Acoustic HD5 and Mirage M-190 pairs.

Thanks in advance
