I have actually found myself moving towards a more stereo output these days, the M60's just seem to do such a stellar job by themselves. And I've been listening to a lot more music them film the last few months. However, I am moving to my new apartment in two weeks (thank god), and will redo the complete set-up. Very excited for this opportunity.
The new media room will be even smaller, though, and I am going to be moving the M22's away from their current surround positions to a Zone 2 position. Which will leave me with the M60s, the VP150, and two surrounds of suspect quality in media room. But I suspect Micah is correct, and that in the new setup I will dial down the center channel just a tad.
