Carada 106" Masquerade masking system.
Paradigm Active Reference 450's front, center and back channel. Active Ref ADP 450's for the side channel.

The good.
Blu-ray and SD-DVD preformance was steller. All the disc I tried worked great. Only one froze up (Max Payne BR) when it was loading. A quick restart and it was fine. All HD DD and DTS formats work great without any problems thur HDMI. I use the AVP for all processing so the analog wasnt tried.
All CD's and SACD's that I tried worked and sounded great

.
A few problems.
First DVD-A all the disc I tried have the same problem other have had. I know this will be fixed with a firmware update so I am not worried.
Second problem HDCD's. First I must say that all of the disc I have work with the OPPO 980, and Denon AVP both digital coax and HDMI. With the OPPO BDP-83 the Denon AVP cant lock on to them. They play but cut in and out. The Denon cant lock them down, like it does with the OPPO 980. I emailed OPPO and they suggested that I try each hookup separately, which I did and still the same problem. I hope this can and will be fix with a firmware update. I quess the OPPO 980 will stay in my system a little while longer.
If anyone here has the Denon AVP and OPPO BDP-83 could you try some HDCD's and see if you have the same problem.
Over all I am Happy with the player. Its well built, looks better in person and its menus are easy to use, and well laid out. Its preformance is steller when using BR, SD-DVD, CD and SACD. I am positive OPPO will get these problems fix, and when they do it will be the player to beat. I am not going to vote just yet. I want to spin a few more disc over next week, and make sure I dont have anymore problems to report.
