what really gets me excited about how x vs y speaker is how it images with depth and accuracy of a image...hifi shops usually dont have speakers setup so you can hear the image so many feet behind them...they have all the speakers semi close to a wall I suppose for more walking room. maybe its just a gimmick, but I really enjoy having the entire wall of sound 8 ft behind the speakers. focals or revels dont do this like magnepans do.
