ATC designs and build monitors. They are flat and honest. They have been designed to reveal the quality of what they are fed with as effectively as possible in an uncoloured and natural manner. The only way around this look at speakers which warm up the sound. However this warmth is distortion. So that’s the choice.
Please take at ATC's Corporate brochure for a background on ATC's take on loudspeaker design -

"The aims of the forefathers of the industry seem to have been completely forgotten and many loudspeakers of today's manufacturers are described as being musically involving, having pace, rhythm and slam or as just being a musical experience, words which might have a definite subjective meaning to the originator, cause confusion and suspicion in the mind of the public, and provide the less scrupulous with a cover for rather cynical products poorly engineered."
