Y'know John, I've been playing around with all those small and large settings and I would have to agree that for HT small all around with the sub cranked way up provides the best (loudest and clearest) sound. For 2-channel music though, I reset the M60s to large and turn the sub down (unless it's reggae or some other bass emphasized music - I keep the sub volume high). The sound from the M60s set to large is just softer and more natural sounding to my ears.
