Your list is a good one. I would definitely try to add Tannoy to that list as well - in particular the Kensington SE at about $8k. If you found a store selling Audio Note - then you should be able to find one selling Tannoy prestige series speakers.

You already know my preference here is for the AN E (In corners to generate the pressure of instruments is ideal) - but I would advise you to make sure to listen for long periods of time to all of these and try not to focus on aspects such as bass and treble but on timbre and tone - and on wide selections of recordings. What I have found on B&W at least to my ear is that they have "impressive" drivers that don't necessarily integrate very well.

On many of them they have issues at the top of their passbands with their kevlar or FST drivers. It's a heightened sense of what is commonly referred to as detail but I believe to be something else. But plenty of people like em fine - still I would give many a listens before I took the plunge. The Tannoy advantage is that dual concentrics tend to sound extremely coherent like one driver and many are very easy to drive allowing more amplifier choices - especially of the low watt variety. Dynaudio Contour for me is more slam than finesse - kind of a bullying speaker. Nothing at all wrong with them - but I would pick them for people looking at speakers for home theater or pulling double duty as more home theater and still good for music compromises. They also don't have the efficiency for lower powered amp choices and I find them a little too expensive for what you get. PMC and ATC are an alternative for that kind of sound as well.
