G, another welcome, and yes, if you were able to hear the the M60s it would certainly give you a good idea of what Axiom offers, although the bass extension of the bookshelf models would be less(without a sub). The M22s in particular would be very similar.

If you haven't seen the November 1 Goodsound review of the X-LSs, note in particular the comparison made with the Axioms. Keep in mind that if you got say M22s, Axiom offers a 30 day trial period. I can give the M22s which I've had for about four years(bought them unheard, due primarily to the excellent Soundstage review with NRC measurements ) the strongest recommendation.
