I finally dialed the M3v4 into my living room. The soundstage is, like Willem Dafoe exclaimed in The Boondock Saints, "frickin' huuuuge!" It's well beyond speaker boundaries with lots of aid from lateral reflections.

They're 12.5 feet apart, well away from room boundaries and the MLP is 12.5 feet away. Now get this: toe-in is extreme so they cross 2 feet in front of my face. Don't ask me the theory behind this. It's the only way I can get them to stage good in this totally crappy room. I have to be careful with the volume because I end up exciting all kinds of room effects. I can get it more than loud enough for my needs though and I've discovered my ears and the 17 year-old Denon give out long before the M3s do.

Later this week I'm gonna try the M5s in this room.
