I wonder if ordering a set of M22s before the BIG purchase might be in order, then you could get a very good feel for the Axiom sound and I beleive as the W series is more expensive, Axiom might be willing to pay for the return shipping of the M22s in order to get the full HT purchase. Maybe call and discuss something of this nature with Axiom.
