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
