@soix, this stuff really gets you riled up doesn't it? While I appreciate your concern for us, the solution is don't read his posts, don't reply to them. You would be surprised how much that would eliminate the problem of lengthy threads about misbehaving dealers and bring you and others much peace of mind.
Personally, I don't think that Dave is going to trap anyone into buying something they don't want.. As long as he discloses that he is a dealer for the product he is recommending I think he's within bounds.. His 14 day unconditional return policy on the 432 EVO is something I would like to see other dealers offer more often.
I don't think there are many threads on Audiogon where someone asks what do people think of this product, and he immediately gets numerous responses saying forget that product, buy this one. It's so common I would be surprised if I read a thread where it didn't happen.
