Mike,

I'd agree with JohnK; Axioms are efficient enough that you could match that receiver with any 8-ohm axiom speaker.

More important to your choice of speakers would be the size of your room, and whether you know you prefer one of the two axiom sonic styles- 'laid back' (m3, m40?, m50) or 'accurate' (m2, m22, m60, m80). And, of course, avoiding buyer's remorse if you're prone to that.
