Agree with sirquack. I wouldn't choose the Panny digitally amplified to drive M80s, but I am certain that the 100 wpc/6 ohms SA XR receivers will have absolutely and unquestionably no trouble driving any other Axiom speaker.
I drove a pair of M3s and M22s with a 5 wpc tube amp and to say there was no problem is an understatement ... a thing of beauty.
Most of the time at moderate listening levels your amps are not putting out more than ONE watt (though spiking to 3 watts) to drive your Axiom speakers.
