Brands that require dealer for service

I have a couple pieces of Linn gear that I like, but one thing I don't like is that Linn requires you to go through your local dealer, if there is one, for any service issues. For equipment I've bought used through the Internet, I find that inconvenient and not a value-added step from my perspective.

I'd like to know what other audio companies require you to use a local dealer for service issues, rather than communicating with and shipping directly to them? This would be a factor in future used equipment purchases.
