As already mentioned in another thread i think splitting up the midrange like is done in the XVX is a risky endavour .
The wilsons i liked most had either a 6 or 7 inch mid connected to the tweeter .
About 6 months ago I auditioned the Sasha DAW's and Alexia 2's one after the other in the same room with mostly the same gear. While I did prefer the Alexia 2's a bit more overall I did notice that the DAW's had better detail in the upper midrange. At the time I put it down to the DAW being the newer model but perhaps you are on to something and the separate driver cabinets had something to do with it.
It's not germane to this discussion, but what the 2's had that the DAW's did not were fuller bass and a taller soundstage. The latter was the killer feature for me between the two.
I would suggest Stirling Trayle. He travels all over the world including Asia. I think he visited Audio Exotics in HK as well. He has even setup systems for reviewers and manufacturers, including Wilson as Munich. Hope this helps!
