depends on what you plan on doing with it. they are both designed for different purposes in mind. personally hands down in a home or studio enviroment the crown will destroy the QSC. if you are looking for a PA amp then the QSC would win out of the two. I've heard them both and I am a dealer for both companies. The MX stuff is on the lower end of the scale for QSC. They have better products in a better price point like the PL-230. Crown also has a better amp in a better price point too. It may not spec the same as the Reference 1 (not much in the world can) but the Crown K2 is a great amp. I have installed them in everything from clubs to homes to touring pa's. The best part is it's convection cooled so no fan noise. It's not as much power either but you will fall in love with it. It was the first PA amp to be reviewed by home audio magazines and it got great reviews. if you have other question i'll gladly answer them.
