Thanks Klipsch Guy, , man you really need to change your name. I have spoken to Dan only via posts on AV123. I'm fairly certain Lonnie has spoken to Dan about the problem I am having. There is another guy on AV123 with Ref 1's, which are bookshelf but still 4 ohm design speakers. He is having the same issue with his Denon 2807. At first we thought it was the Denons.
Anyway, Lonnie was supposed to send me some replacement amps asap. I have not received them yet. I will follow up to see if he has spoken to Dan.
