I disagree with Judy. Most particularly because he/she has an obvious negative bias against B&W as noted in other posts he/she has made. His/Her bias goes far enough to make things up which are not true and cannot be proved.
Besides this apparent negative bias her logic is fallacious. Just because there are used B&W speakers for sale (no matter how many) does not lend credence to any negative inference (which she would like you to infer from her statements).
For instance, my dealer is now selling these used items acquired from me on a trade in: 2 B&W 703s, 2 B&W 705s with stands, B&W HTM7, and a B&W ASW 750. Why? The reason is because I traded them all in to upgrade to a pair of B&W 802Ds. I flooded the market with series 7 B&W speakers to upgrade only my front, right and left, speakers. So one could easily infer from Judy's statements and mine together that people like their B&Ws so much, they upgrade them a lot, and possibly upgrade from a lot of lower end speakers to one or two high end speakers.
I've noticed that a lot of dealers are kind in this respect, I'm guessing the reason for so many B&W speakers being up for sale, is likely because of people like me who got their feet wet and realized after a few months it was better to spend the extra money and build up to a top end system now, rather than re-buy everything later on and waste more money along the way. Then again, there is also the question of upgrading to newer models, which would explain why so many older models are on the market. This likewise proves that people must love B&W, for why would people have bought so many of them, and then sell them when there are new models with newer technology in them available. These are all reasonable explanations. Add to that, the knowledge that B&W is like the 2nd biggest audiophile speaker selling company in the world, or something akin to that, and it makes a lot of sense why there are so many to go around.
Judy's posts that I have read so far seem to follow the same agenda. Trash talk B&W then recommend the same groups of speakers she/he always recommends which leads me to believe there is an ulterior motive involved... like perhaps marketing.
