Part of the decision depends on what you have experienced and what your expectations are. I just bough an HK AVR240 along with a pair of M22Ti's and a VP150. I am using my older sub and surrounds but the sound is fantastic and plays plenty loud. The AVR 240 will drive any of the axiom speakers but if you can afford the Epic 60 or Epic 80, you may upgrade to the 435 or 635 just for good measure. It sounds like your budget is unlimited.
