I believe that Axiom offers a in-home trial period sort of like Outlaw's. If you really have your mind set on them, then you might want to take a listen. If you don't want to pay full shipping costs, just try out the front main pair first. If you don't like those, it won't matter how good the surrounds sound.

Are you happy with the Paradigm sound? If you are, their higher level speaker series always get great reviews and there are a bunch of Outlaws around here using some sort of Paradigm set-up.

You're really only limited by your budget. I would find as many systems as fit into that range and try them all out, if possible. As far as reviews, name a speaker brand and I'll find you a good review for it online.
