LOL, your post was enough for me to bring out the two
I won't have the time to this thorough now but here's some initial impressions/thoughts:
I couldn't help smiling for myself when I switched between thw two for the first time. The feeling is very similar to that of shifting between the CKR9's and 10's, you can clearly hear that they're siblings but despite of that the presentation is very different between them.
The BE's has a much more airy sound and an overall slightly brighter signature with better soundstage width.
The AN16's on teh other hand has a much more intimate presentation with an fuller sound and better soundstage depth.
Despite the AN16's being overall fuller the subbass extension on both is very similar.
Just like the CKR siblings they're much more complements to each other than direct competitors.
I really couldn't say that one's more technically capable than the other but your prefernce, music, source and mood would be the deciding factor on which to choose.
The XE800 is much more similar to the BE's but with a bit softer bass and ever so sligthly more recessed mids.
