Welcome to the forum! Keep in mind that although auditioning somewhere else is a nice option to have, the in-home audition is likely your best bet.
Each room has a different, and major, influence on the sound you'll get. Hearing ANY speakers somewhere else will not necessarily tell you what they'll sound like in YOUR room.
Some people think that the benefit of being able to really listen to the speakers over 30 days is an enormous benefit to buying from Axiom. The worst case is that you send them back- but the return shipping is not really all that much...especially if you think of it as "rent" for having the system for 30 days!
