Thats justnot my experience. The majority of buyers are not, by definition, enthusiasts. Some may become enthusiasts after finding a forum but most don't. They buy some gear, they have it installed, they enjoy listening to it and if they feel like they have gotten value for money they might buy some more or recommend their friends to visit the relevant dealers. This could be proved very easily by wasting a few saturdays in a shop, I have done I many times.
