Welcome and congratulations on the coming Axioms.
While not cheap, Axioms are a very good value and compare favorably with more expensive speakers.
They are efficient / sensitive also. You might find that your amp does fine for your needs depending upon the demands of what you're listening to, the size of the room and whether or not you have a powered sub to remove some of the burden of the M80s playing full-range on their own.
Be aware though, that speakers such as the M80s are more likely to be damaged by an under-powered amp driven into clipping than a much more powerful amp that is running at half it's output on loud crescendos!
