I live in London and have direct experience with three of these shops. Because there are positives and negatives I would prefer to pm you. I'll try and do it later today. Pieter

This is probably the best HiFi store in London:

Harrods in Knightsbridge is also worth a visit, not necessarily high end HiFi, but interesting. Also, probably the best department store in the world IMHO. Harrods also has a great selection of restaurants with a food hall second to none. I tell all my American friends, Harrods makes Neiman Marcus look like a Walmart!
