Frank, I think high end dealers recognise tyre kickers the world over. Even if your a keen audiophile, if youur not buying, your a tyre kicker.
The highest end is probably:

I have never been there, but it stocks pretty elevated stuff. Most of the high end stores are closed, replaced by guys working from home, like Graham of Tron amps fame at GTAudio and Keith at AngelSounds Audio, both are near London, but they are set up for specific demos. As Bjesien says,Walrus is a great store, if a bit idiosyncratic, run by real enthusiasts.
