John, another welcome(we can always use another John here). As to power requirements, "handle a lot more" doesn't mean need a lot more. Although the M80s have been lab tested by Axiom at over 1000 watts without going up in smoke, they're also slightly more sensitive and require less power than average. You didn't describe the configuration of your present Orbs, but the single unit is a lttle less sensitive than the M80s and you might find that the M80s will actually require a bit less power. In any case, there's no good reason to assume at this time that the 2700 won't be entirely satisfactory, so it's at best premature to be thinking of another amplifier.
