I'm looking at the both the 4806 and the 4806CI, and I'm most likely going refurbished through Dakmart. I believe Denon has resolved all the firmware issues and after speaking with Dakmart yesterday they claim to have all the latest firmware updates, but they also told me most of their 4806's are being upgraded now to the 4806CI so it makes me wonder if I should go with the CI.
