I have used Richer Sounds on and off since the 80s when I first discovered their London Bridge shop. As a customer I always found them helpful and obliging, and enjoyed the slightly quirky approach. They seemed to move from the bargain basement approach to embrace listening rooms and decent mid-range gear and the shops gradually smartened up over the years.
It appears that Mr. Richer is indeed something of a model employer and is giving his employees a stake in the business as he retires, instead of selling up and riding off into the sunset. Good for him I say!
