Your first step should be to decide for yourself whether better CD sound or a better picture is your top priority.
I own a Denon 2200 and a 2910, as well, and I really like how easy they are to use, along with their versatility. The 2200 you own would make a good transport if you want to explore better audio through an external DAC. There are endless recent threads on the merits of that approach and the choices range from less than $200 to multiple thousands of dollars.
