For $1000, including parts to make some minor modifications (the TI opamps MUST go based on the results I now have with the modded SE here), the BDP-83SE is a great machine. It's sonic balance still leans toward the lean, neutral side of the house. But for what it is, it's a very nice machine.
The Oppo 83 is better than the lower end Oppo DVD pieces for non-bluray content. I know, I've got them here and did a head to head just in the last couple weeks. The differences were more than subtle, especially after calibration of my JVC RS25 on 100" Stewart screen. The Oppo pieces are exceptionally good value for video playback. But the 83 is their best piece in that regard.
The bonus of the 83 is that it plays absolutely everything you throw at it. I've yet to trip it up with SVCD, Divx, MPEG4 content, DVD-A, SACD, badly done multi-region DVD, Blu-ray, etc. The only thing it's missing is HD-DVD for the disks I have here. That's it... If you are never going to use any of this content and only going to play regular DVD content, you're missing the point of its capabilities and it then becomes a much more questionable value judgement. As for whether or not you should be watching Blu-ray (or even AVCHD content) over the same content in regular DVD, that's one comparison where I'm always going to choose the HD content... no ands, ifs, or buts..... and yes, the 83 is much better than the $200-$300 Blu-ray players I've been trying. JVC had one that was fast to load and had decent picture quality. But it was still not as good as the Oppo.... if you are only going to use the player for video playback via HDMI out and not as your music source, the cheaper Oppo blu-ray player is exploring.
In the context of the system this unit is likely being used, it's a heck of a deal at the price. As long as you work within the context of it's leaner presenation with components that bring the overall system more to your tastes, it's certainly better than any other $1K universal player I've ever tried.... and better than a lot of $2K CD transports and players I've tried as well. It's certainly better than the Pioneer and Denon players I have used in the past and costs a whole lot less. A very good mid-tier component that offers video that rivals some of the best and audio that's a whole lot better than what you find in $300 machines (this refers to the SE, not the standard version... which is not an audiophile sounding piece at all).
