I just purchased a Pioneer Elite receiver (they also sell Denon) from a store in San Diego. I don't know if they are an authorized dealer but I was thrilled with the service and pricing. They gave me the best price I could find on the receiver I was looking for.

The gentleman who helped me is named Scott. His email is soundpros@earthlink.net and he responds to questions very quickly. Try firing an email to get a quote or warranty information from him. There is also an Ebay store ("Soundpros 877.894.6751"). I hadn't heard of them before but there are no complaints on the BBB, it has good ebay feedback, and my experience was truly excellent.

Good luck.
