I would imagine that the 330 would have enough juice but it all depends on your preferences and the only way to know for sure it to pair it with the Axioms and see for yourself. I have the AVR135 and M60, VP150 and some nondescript surrounds. The 135 does just fine and I've never had to turn it up past -15 for movies / -20 for music (although I am in a 1500 sq ft room).

I second the suggestion that you calibrate your system.

Let us know how it works out for you.

Cheers,

Jordan
