I used to have a pair of B&W 805S speakers. I bought them in 2006 when I believe they listed for about $3,500. I used them for about three years. The 805S doesn't have diamond tweeters and are no longer manufactured. The 805D has the diamond tweeters, are still in production and are more expensive, but will sound better. I thought the 805S was a great bookshelf speaker. I ran them with a 100-watt Arcam integrated amp. I currently have 803Ds on my Bryston system. I really like the B&W sound. Very refined, IMO.
