Having owned both Bose 901 and now Magnepan speakers I don't see how anyone can compare the two. Magnepan is everything Bose is not, great sound, realistic, fantastic imaging, definition, everything thing an audiophile could want if you have the proper power and set up. Maggies have lightening fast realistic bass down to their limits so if you have one of the smaller models a sub is needed if you enjoy music with deep bass content.
