So I've watched a handful of movies so far on the X800, and overall I'm pleased with the PQ. Definitely better than the Samsung K8500 (which I sold on Craigslist), and on par with the Panasonic 900 (that I returned). However, I still give the edge at this point to the Oppo 203. I feel the Oppo does a slightly better job with balancing specular highlights with shadow detail on screen at the same time. On most scenes you would never tell the difference, but on some movies/scenes (like Pacific Rim 4K), I feel like the Oppo fleshes out a bit more shadow detail. Again, probably too close for most people to notice. And given the fact that the Sony is only $300, I would highly recommend to any potential buyer looking to get into the 4K Bluray game. I have the privilege of owning both, and like both players a lot (especially since they both play DVD-Audio and SACDs). Just my 2 cents..
