I have owned both. Maggies first then went to B&W 802's, just sold them for B&W 800's. The Maggies were great, my only complaint was the lack of bass. I installe the Vandersteen 2wq sub which made a big difference but, it was another component. The other issue with Maggies is the overall size, while not deep they are tall and you have to have enough room both behing and to the sides or they just will not sound as they should. I had 3' to each sidewall, 10' to the back wall and still could have used more room to the sides. The Maggies are much more forgiving as far as source equipment, B&W's will let you know about all the flaws in your components, cables, and disc's or vinyl. But once matched with the correct components they are just as musical in the mids and highs as the Maggies, and have a deep well controlled bass that is awsome for jazz, rock, blues which you just cant get out of Magnepan's. If you purchase the B&W's you will find that you own some cd's you will only listen to in your car. Poor recording quality is extremely noticable. Having owned both, I prefer the B&W's, they are just as musical, easy to drive and have good deep bass, and take up less room. On the down side they are twice the price of the Maggies. If you can afford the B&W's go for it. If you really want to torture yourself listen to the Nautilus 800's.
