What a load of absolute bollocks. Whoever you are, you have, perhaps, a little bit to learn about what is required of studio monitors. They are designed, by many different companies, to be used as extremely accurate transducers, so that the recording engineer can hear precisely what is actually on the tape. He's listening for problems. An "inoffensive" (read:inaccurate) midrange would be an absolute disaster.
The fact that ATC monitors are world-famous in a competitive environment like this professional marketplace - where the people buying are not "badge sensitive" like the hi-fi weenies are - suggests that the professional users can't hear the problems which you are pretending to perceive with them. How likely is that?
