Personally, I find the idea of trying to get speakers that work with a particular amplifier (ie, I want the XPA-5, so I won't get the M80s) some what backwards. Now, since you haven't heard the Axioms, so you don't definitely know that you like the sound. Remember, speakers make a whole hell of a lot more difference in the sound than amplifiers.
