While browsing ebay and other online sites I've come across some Denon's that have a different model numbering than the convential line they have. The models are 885, 485, 985, and the like. They seem to have specs that are the same as the other line but I was wondering why they are numbered differently. Can someone enlighten me? Also, if they are the same basic product, could you post a link that shows which model matches up with which ie 885 = 2105.
