I have the Merlin TSM-MMe-s and they're excellent. They are sensitive to placement and, optimally, your seating position should be least 9 feet back. Merlin provides a set-up jig that helps get the toe-in correct and I have found that they sound best - in my set up - slightly tilted back. One advantage of the Merlins - depending on the size of your room - is that they are a sealed design and, therefore, may be less boomy and easier to integrate to your room than ported designs. Also, the Merlins like tubes and I believe user opinions are more varied from those using ss.
Another speaker I have experience with is the Tyler Acoustics Taylo monitor, which is also an excellent option to consider.
