Would you mind directing me to the link? I am considering a new Denon and this model was one of my options. I'd like to see just what happens in an upgrade. Thanks very much for posting this information.
It is at the Denon site in the owners club, Which you can not get to unless you regester a product, sorry about that. What I will tell you is they are great about updating their products and also the 4806 is just awesome you would just love it. From the great sound to all the options and ablity to tweak. Any specfic questions let me know.
