Last month both Newegg and a Denon rep confirmed that Newegg was an authorized reseller, apparently purchasing product through another authorized reseller so I posted that information in this forum. With the recent posts of Denon CSRs indicating that Newegg is in fact not authorized, I made some calls yesterday to both Denon and Newegg. A Newegg supervisor again assured me they were indeed authorized to sell Denon AVRs and that they would assist with any warranty issues when dealing with Denon. I noted the incorrect 2 year warranty listing on their 2112CI webpage, which apparently was just an oversight, thinking all Denon AVRs had 2 year warranties. I then called Denon CS with one rep saying, "not authorized" and another saying "I heard something about them being authorized but not sure" so I emailed the Denon CS Manager who although initially indicated they were authorized, later in the afternoon came back and replied they are not authorized.
Edit: Final resolution - Newegg is NOT an authorized reseller.
Going forward; however, until Newegg is able to establish itself as an authorized Denon reseller and is recognized by Denon as such, I would suggest to continue using the known authorized resellers (eg. Electronics Expo, AV Science, J&R, etc.).
