Chris, you certainly should be aware that if the frequency response is flat from 20-20KHz and the noise and distortion are at inaudibly low levels(all accomplished at quite low cost these days in all competently designed units)that there's no audible difference in the sound when the designed power limits aren't exceeded. There's no personal opinion or "notion" involved in this; basic principles of audio technology are applied to provide transparent amplification and claims regarding differences(sometimes "huge", "night and day", etc.)collapse when all the variables(especially holding sound level to within 0.1dB, a common failure in casual listening)are controlled in a proper blind listening test. This is well-established.
