Seems like there are loads of ABX listening tests (Carver Challenge, etc) which tell us there is no audible difference between any amps which deliver sound at your top listening levels within their design limits. Any particular choice of amplifier above a basic good design (about $400 seems to be enough) would be justified only if you deliberately seek some distortion type of your choice.
