What is the real difference between Stereo and Mono configurations in Amps? Some amps claim they can do 150 watts Mono but only 75 watts stereo. But if we're talking about how loud the amp is do the 2 75 watt channels end up equalling a 150 watt sound ? (not that i'll ever crank an amp that loud, or at least not for a while). What are peoples general opinions of stereo amps, both Combo and Stack.
