I have only heard them during a day at the recent Newport Beach Show. They are in my opinion an enigma. They have a full, immediate sound in the midrange and do a terrific job of disappearing, i.e. if you closed your eyes you would have no clue as to the speaker location. Voices and instruments have a robust presence. Highs are well-defined but sweet and not promiment, calling no attention to any part of the treble or specific instruments. The enigma part comes with the fact that they are extremely fast like a good panel speaker, especially in the bass. On one particular orchestra recording the bass had a transient crack that was unreal, making bass from virtually any other speaker I have heard sound slow and discontinuous, while still doing a good job with extension. It was hard to believe that these little speakers could have this type of speed and impact throughout the frequency spectrum. I heard a lot of speakers at the show and the only ones I thought measured up to the MMMicroOnes were the mbl 101e's as part of a very expensive setup--everything else was somewhat disappointing. While some have opined that a lot of the sonics were due to an expensive front end, it just indicates to me that these speakers are merely limited to the quality of the associated electronics. Maybe not everyone likes this type of sound but obviously I was impressed and ordered a pair.
