I am completely new to this, so bear with me. I just bought a pair of M3s, and so far I really love them, but I'm using them as mains in a fairly large and open room and am wondering if there's any advantage to trading up to the M50s -- which are about the most I can afford at the moment. The reviews of the M3s are stellar, and I'm wondering what I'd gain from moving up -- if anything. (I'm using the M3s with a sub.)

Thanks
