welcome dchui,
if you are interested in hearing an Axiom setup before you buy, try checking here -
Audition Thread. There are numerous Axiom owners willing to offer up their home for a demo, hopefully you can find someone close by.
The B&W 600 series are generally thought of as more laid back, without the clear mid-high end that Axiom's have. If you are unable to find an Axiom owner in your area, try auditioning the B&W 703s. They are generally considered similar sounding to the Axiom M60/80s, and when I listened side-by-side with the 604s3, I felt the 703s were certainly the better speaker (much cleaner, more revealing high end).
Good luck!
