Is it worth changing from B&W N805 to the 805S?

Yes...and I would disagree with Elizabeth for two reasons, 1) there is no announcement for 805D's and 2) if B&W did come out with such a speaker, they would cost far more than the 805S's and suspect they'd be more than you are looking to spend.

I am skeptical of them releasing an 805D. However, even if they do, there is not even rumor of it yet. That tells me we aren't even close to seeing one. I agree with Brian though, if we do see one, I expect the retail cost to be around 5000 a pair.

Thanks guys. Honestly I would not be interested on the 805D (if they were to exist) as they would be much more expensive than the 805S I guess.

As you now, the main criticism to the N805 is often related to bright highs, and I tend to agree with that perception, basically that's why I'm looking to upgrade to the 805S, hoping that these have a little more gently highs.

Any other comments will be appreciated. Thanks

Hi, I have both 805n used in stereo. then changed to 5.1 and bought 805s with htm 4 for center and the asw 825 to complete speakers. I really would be pressed to say there is much difference in the 2 models, except for the highs, just a bit brighter. I like both models very much. They do look slightly different. less steel on tweeters rear tube on s model, and the tweeter center cone is smaller s models. Over all size is the same. And the stands work for both models. Good luck

To answer your question, undoubtedly yes. But to sit around and wait for an 805D is silly, it is not going to happen. Anyway, if it did you could easily upgrade through a dealer or sell them here and get into something new. B&W's sell incredibly well on the used market.
