Cork, as always it depends on the loudness levels involved, the sensitivity of the speakers and the listening distance. You've made a non-sequitur by saying that you're not worried about volume, but being able to drive the Axioms "sufficiently". The two are the same.
The 1602 at typical listening distances around 10 feet can use about 50 watts to drive the M22s at peaks of 102-103dB. If this is sufficient for you(and it probably should be if you value your hearing), the 1602 would be a good buy(especially the A4L deal)and there's no purpose in buying unused amplifier power.
