High end dealers around London, UK?

Walrus is excellent, there are some excellent dealers near to London, working from home, I have bought from and trust, including:
Trevor at http://www.guildfordaudio.co.uk/

Keith at http://www.angelsoundaudio.co.uk/

Absolute sounds is a distributor, not a dealer and I have found them a bit of a pain and not interested unless you have £100,000, burning a hole in your pocket.

Trevor and Keith are both great and will build a system to suit your pocket

I still have it on my list to visit Definitive a/k/a Living Voice. Cool, Edwardian
factory building as showroom/facility. I'm overdue for a trip to the UK, and
will try to hit it along with a visit to the Morgan factory in Malvern.
PS: Definitive is not in London, but about 200k away- probably worth the
drive if you set up an appointment in advance.
