Sticking to my budget, I only auditioned the B&W 804 D3 speaker and in comparison to a friend's B&W 804s, I found that the D3 did everything better. The D3 sounded more coherent and had better driver integration than its S counterpart. I also found that the new "gray" midrange driver looked better than the old "yellow" Kevlar" midrange driver and I also found the fit & finish nicer on the D3. I have no experience with the N series.
BW 800-805 D3 series VS 800-805 Nautilus/S series
I love the Nautilus and S series but hit a wall with the D series. At the end of my trials, the 800 N & S speakers always sounded more natural and right to me, personally. I have met others with this same opinion, surprisingly quite a few.
I'd like to know, if you share this sentiment, have you heard the D3 line? What are your opinions in comparison the the N & S series? Have they found their way back to the magic or not?
