After 12 years with my current HK prologic reciever I have decided to purchas a Denon 3808ci

I have searched online and found that the authorized Denon dealers are all $1599. for the reciever but have found prices as low as $1100 from other online stores. Should I pay the 400-500 more to get it from the authorized dealer. Why such a large price gap. I belive the factory warrantee is the same.

Any advice would be helpful websites ECT.

Thanks

Larry
