If I wanted to create a respected speaker brand one of the first things I would make sure I did was be very selective about where my product was sold. To discourage people that didn't meet my standards limiting the warranty would be a great way to make it really hard for the people I didn't want selling my product to be competitive. Protecting a brand name can be a very delicate business. And while I know that there are idiots in every store, if you go to the custom shops I think the odds are higher that you'll find someone at least familiar with the terminology. Those shops live and die by referrals, and if they don't deliver something that their customers are happy with they'll go out of business. That's why you'll never see a kid working at a place like that in the same way that you'll never see Paradigm for sale at Circuit City.
