Depends on what features/inputs/outputs you need as well as your budget of course. Although the 3312CI is the successor to the 2807CI, you could be just as well served with a 2112CI if you don't need the additional features offered by the 3312CI (ie. preouts, dual HDMI outputs, Zone 3, etc.). Review post #2 in the Denon XX12 Owner's thread linked in my sig for a comparison of the various models. Note however, that the new XX13 models are due to be announced in the next few weeks and released in May/June so you may want to wait to see what they offer.
