Surely the most receptive host would be a Meridian dealer.

My local is Grahams Hi Fi. They are good guys with 2 listening rooms and a large open plan shop front.

They are near to Kings Cross station which is well connected to Gatwick and Luton airports plus the north of England. Within London it is well connected being on several tube lines.

Best of all ... it is walking distance from my house ....
