Interesting that Atkinson speculates the 800D was voiced by ear, and KR mentions sparkly highs compared with the Salon 2s (a classic trick for getting attention at dealer auditions). Since I have a dealer a couple of miles from my home that displays 800Ds I always listen to them first, and my impressions mirror JA's, and KR's complaints. How KR came to the conclusion about how wonderful the 800D is I can't understand. There are few things in high-end audio more annoying in the long run than "ruthless" high frequencies, as KR calls them.
Unfortunate, because I think B&W has the technologies to build a really work-class product, and yet they seem to focus more on marketing and tuning for auditioning than accuracy. That's strike three for me.
