I have owned the following B&W speakers in order: 1 B&W DM640 2 B&W Matrix 802S3 3 B&W Matrix 804 4 B&W Nautilus 804 5 B&W Nautilus 805 I like the 805's and will not sell them. I enjoy them more than any of the above list. Build is far superior to the matrix series. I have always liked B&W sound but I think N series speakers are more refined than the Matirix series stuff. As for why so many for sale - just a factor of how many were sold.
Why lots of B&W Nautilus for sale used?
I see a lot of B&W Nautilus speakers for sale, mostly 804s and 805s and some 803s. Considering the Matrix was around for 10 years, you would think there would be lots of them for sale from upgrading, but no. So is the Nautilus really better than the older Matrix overall despite what we hear??
