Well folks, Mirage finally brought a smile to my face and i guess thats about the best compliment you can give a speaker (or equipment). Process of breaking in might be painful sometimes but all the more rewarding afterwards. The soundstage opened up, thanks to me moving them around too, and resolution has gotten considerably better.
That's why I was so enthusiastic about recommending them. Some speakers sound actively irritating out of the box until they settle in and reach their intended tonal balance (e.g., Totem). Mirages aren't like that. Out of the box the tonal balance is OK but the thrill factor is meh.
Give them 100-200 hours, though, and the low level resolution starts coming in. Pretty soon you start hearing things that you might not have noticed before. In my case, I particularly noticed the richness and detail of subtle vocal harmonies and call-responses between two or more groups of vocalists. I don't think the Mirages' improvement in resolution and detail let up for about six months. You will love these speakers even more as the months go by.
My opinion: They put a smile on your face because the tonal balance is very natural and the dispersion energizes the room like live music. They have a natural presentation that makes you forget about speakers and simply enjoy the music.
To get a better L-R balance, you might try either some sound absorption behind the speaker that has solid walls behind it or putting something reflective near the other speaker.
