Thanks for everyone's input. I was looking for more features such as video chips, build quality, and networking capability.
For the price I could afford without going crazy, I went with the Onyko TX-NR818. The newer Onyko TX_NR828 didn't offer the Audyssey XT32 calibration. I looked and studied for about three months before buying and after reading many reviews both pro and through various vendors that rate HiFi gear, and felt the best way for me to achieve what I was looking for was by being patient and speaking with a lot of people who not only enjoy good sound, but have the passion for it. Thanks to everyone for your input, for me it never gets misplaced....Rich
