Axioms are not bright no matter what some AVSforum members will tell you.. Also, solid state receivers are designed to have a flat frequency response from 20hz - 20khz, so they won't make speakers sound bright. Now, if you have some special DSP or tone controls turned on in the receiver to alter the original sound, that could change the outcome.
That Yamaha will do just fine, Axiom speakers are very efficient and require very little wattage to drive to loud levels. In most situations your only going to be using 1-2 watts anyway.
