This links Michael Fremer 's article comparaing the efficacy of several vinyl record brushes.
The two that won his very un-scientific survey were brushes from Hart Audio ( Under US$100 ) and the Ramar. But it does appear that there are big differences in cleaning abilities.
It was this article that launch the Ramar brand. On a seprarte video which I cannot find, the owner of Ramar, Rangel Vasev, bumped into Fremer in the corriodor of Munich Hi Fi show. He thanked Michael for allowing him to quit his daytime job and attend to his small business full time. I had always associated Ramar with this video which I can't find. A young entrepreneur fulfilling his dream .... What's wrong with that?
