I have not heard the 803D but did a direct comparison between the N803 and N802 and the N802 was clearly superior in the bass and mid-range. The Marlan enclosure for the mid driver in the N802 should not be disregarded. I would expect that plus the more complex cabinet of the N802 to make a greater difference in a room of your size than the diamond tweeter in the 803D.
Comparison of B&W N802 vs. 803D
The Dealers seem to be split on the performance of these two B&W models. I have the opportunity to buy either one in excellent pre-owned condition, though the 803D will cost an additional $1,000. My room is 20'Wx26'Dx10'H with good acoustics. Is there a clear sonic winner here? or is it too close to call, leaving asthetics and the purchase price to be the deciding factor?
Thanks!
