I auditioned the MA6900 back-to-back with the C46/402 combo (with B&W N803) and the latter is definately better. However it also costs twice as much! I wouldn't say it was twice as good - they were quite similar overall - but there was more detail and ambience with the combo. That same day, we also played with the C45/252 combo and I think it was closer to the C46/402 than 6900 in terms of amount of detail. Otherwise, very very similar. Arthur
