I don't get why manufacturers will not warranty internet sales. I mean if it's a Denon 5803, then that's what it is, is Denon claiming they did not build it? It must have come from their factory. Are there other companies building Denon 5803's. I don't thing so. Second, how are these people getting the products? Denon is building them, Denon is shipping them, but then they won't warranty them. I say if it was built by Denon then it should be covered by Denon. It's a total scam, you know they are sending them to the unauthorized dealers.
