I have ML Montis speakers in my 2 channel room and I love them just as much as the original poster on this thread. I have heavily treated my room to make them as good as I possibly can, and I spent hours and hours and hours dialing them into the "perfect" location for my main listening chair. I agree that the shortcoming of these speakers is the very small sweet spot for listening. If I move to the adjacent chair in my room, the sound stage is underwhelming and not even close to what I experience in my primary listening spot. For me, this is fine because I am the sole listener for 99% of the time that music is played in this room.
I have visited many high-end audio stores in search of a system that sounds better, but I have not found that system yet (and I have listened to some very pricey systems). I would love to find something that I like better, but I haven't - so I guess that's good news. I'm sure my wife is happy that I am happy with the current system!
