Infidelity - A great little hi-fi shop in hampton Wick
They give great advice and are not pushy. They have been responsible for a number of my home tests, Naim Nait 5i, Arcam A70, Rotel and a couple of tuners. Oh, I've purchased a few bits from them as well, most notably my CD player.
Derek once try to sell me MonoPulse speakers about 3 years ago. He said: " Come and listen to these." He had them rigged to the Naim system. " They'll sound impressive with your Arcam," he advised. I replied, " I think my daughter will have a field day with that funny cloth." It was all light hearted, although the speakers did sound rather good.
