Phae, welcome to Axiom. Amplification doesn't work the way you seem to think. Any amplifier, including those in receivers, isn't limited in power output to any greater extent than its official output rating. In the case of your 2010 that's at least 140 watts per channel. The Axioms are of average sensitivity and use about 1 watt at a comfortably loud average output level. Brief peaks use much more of course, but not likely anything that your 2010 can't handle with ease. So, power wise you're already getting the "most" out of your speakers(unless you're considering extreme loudness levels damaging to your hearing). A separate amplifier with a higher maximum output capability can't do anything but add the ability to sustain a louder listening level or to provide more "headroom" for brief peaks. But as I've pointed out many times, if sufficient headroom already exists, unused headroom is simply that: unused.
