having recently listened to some not yet released Bose 901's, they are, without question, the most accurate and faithful speakers I've ever heard, without question. To say that I was surprised, even astounded, is an understatement. Without question, they make Dunlavy's, Mezzo Utopias, name your electrostatic or planar, sound as if they came from some Toys-R-Us children's sound system. The placement of instruments was superb and comments such as were made by Consumer Reports that a violin sounded overly wide, are rendered ancient history. One can literally close their eyes and not just hear violins, but the individual playing the violin in pin point precise location. It is as if you now have the best seat in the Carnegie Hall but without having to climb over everyone to get it. Distortion, as near as I could tell, doesn't exist and cabinet vibrations tax the ability of measuring instruments to record it. A spectacularly flat frequency response, coupled with equalization that is now adaptive to the room allowing for dynamic cancellation of reverberations will greatly simplify speaker location in virtually anyone's living room. It is not everday that I can unequivocably say I have heard the goal in sound reproduction. Today is that day.
