Alex, I do not own the NHTs but heard them when our local audiophile group visited the NHT factory. They demo'd this model with and without the subwoofer. I felt that I would be happy with them sans woofer, but I can't say that you would feel the same. These are part of their pro line and are designed as near-field monitors, so you can be sure of getting proper driver integration close up. They sounded remarkably "right" to me. The NHT folks are excellent engineers with good discipline, a well-equipped lab, and a lot of integrity, but they are not tweaky audiophiles. Make of that what you will. The company overall has a rock n' roll orientation (righteous amps and guitars in several people's offices).
Macrojack has three pairs of M-00's, perhaps he will chime in.
