Hey,

I'll answer those questions (albeit quickly). Yes - stuff in the factory outlet changes very often. Also - as far as whether or not a particular amp will power the M60's enough... I suggest looking up up the sensitivity (in dB) of your current speakers - if the Axioms are rated higher, then they will play louder - if they are rated lower, they will play quieter. Of course, all of this depends on the accuracy of those reporting the specs....

hope I helped,
