If you are going to spend that much on monitors, I apologize to most of the other replies on this thread but I would go with MikeSing's post as the place you should start. Set aside budget to either DIY some acoustic treatment, or purchase from Primacoustics or Auralex. Perhaps 1/3 of your monitor speaker budget. Take it out of that monitor budget. The sum total quality of the monitors you purchase and the acoustic treatment you apply will be better than spending the whole wad on any of the monitors in your list.

At minimum, put absorptive acoustic treatment on any wall or ceiling location where you can see your monitors in a mirror on that wall. Rather than re-type a bunch of resource material on the topic, there are excellent guides to this in many places on the internet; Auralex has some good resources as does Ethan Winer's articles and forum posts. Ethan's posts guide one more to DIY solutions, Auralex towards their own products. In either case, managing reflections is a key acoustic issue to concern yourself with before spending a wad on monitors.
