Jason, welcome. Your 330(and there's no need to use the "entry level" term)should have no problems driving any of the Axiom speakers if it's driving your present speakers to adequate levels for your use. The Axioms are average to slightly above average in sensitivity and don't make any unusual demands on amplifiers.
The 330, which HK rates at 65 watts per channel by the more realistic two channels driven standard used by most receiver manufacturers, is conservatively rated even at that number and likely could justifiably carry an 80 watt rating. The amount of maximum power(average level would use 1 watt or even less)that you'd actually use depends on a number of factors, including how wide the dynamic range of the material being played is, but in the vast majority of cases wouldn't reach 100 watts. From your present experience, this seems to apply to you as well.
