Jerry, in line with some of the previous replies, what you've read elsewhere is simply nonsense that has no factual basis. An overall "bright" characteristic in a speaker can't just mysteriously appear without it having a substantial frequency response inaccuracy over a broad range in the upper midrange/lower treble. Testing reports show that this simply doesn't exist in the M3s(or other Axioms). If a specific recording is poorly done with a boost in that range of frequencies to sound more impressive on mediocre equipment, it'll sound "bright" on Axioms and other accurate speakers which tell it like it is.
