Jim,
I have the Outlaw 755 and M200's, these amps are very clean and will drive the Axioms without any problems. I have the VP150, QS8's, klipsch kg4.2 and pair of home brew 4 Ohm mains.I plan on buying the M80's in the next few weeks to timbre match my system. I'm told that Outlaw and ATI use the same assembly line. (If that matters)...
For the price of the 755, you can't go wrong. I would buy it again. I own Linn and Aragon gear and I feel cheated, it's good gear but expensive and not worth the LOFTY price tag.
If you decide to get the 755, be prepared for some heavy lifting.
Good luck! Let us know what you decide.
Tom
