Welcome to the forum.
The few Jamo's I have heard have been nice, nothing I would write home about. They sounded very much like most other speakers, smooth/rolled off top end, decent bass and midrange, an all around nice speaker, could have been the room too, very sound proof.
Axioms on the other hand play the source as it receives it, good or bad. You really should try to audition a set by looking in the Hearing Things forum for some one nearby willing to audition or call Axiom to see if they have some one not on the list they could contact for an audition, barring this you will need to order a set, start with the M22's cheaper to return if you don't like their sound. The M22s sound very similar to the M60's and if you decide you like the M22s you can then upgrade to the M60 for just the differential in price, no extra shipping charges
