<font color='#000080'>Everybody needs to make money or else we don't get any more products (i.e. they go out of business or reduce their R&D, etc) so basically what happens is that they want to be able to continue charging certain prices for their gear.
When unauthorized internet sales drop that price to ridiculously low margins (via volume), legitimate dealers have to match it (with less volume), and the overall profits for everyone go down. Then the business model collapses.
While I think speaker companies can do a direct-to-consumer business model, R&D would collapse if processor/amplifier companies lost their retailers. Who's going to show/demo products, etc if the retailers cannot afford to carry the items? It's a viscious circle.</font>
