Summary: This unit was great for the first full year. Then the HDMI inputs began to fail. I only have one working input now for HDMI. Going to use my extended warranty now. I recently purchased the 1022-k, hopefully that one works better... still got extended warranty on that as well. Otherwise I love the unit!
Summary: After waiting a very long time to replace my 10 year old Denon amp I did a good deal of research and settled on this unit or a Yamaha and due to the price difference settled on the Pioneer. Right out of the box it was easy to set up and sounded great. The two items I thought were a great touch were the microphone to help tune your speakers to the room and the iPod connection that came with the unit.
Summary: Ready to upgrade our family's 10 year old Sony receiver, we elected to get the Pioneer 820, because it had the iPod connectivity, along with 4 HDMI inputs. Overall, I cannot say this was an incredible upgrade, and I do not feel like the technology has changed significantly since we bought our last receiver.
