Had the Panny DP-UB9000 for just over a week ... watched one of my 4k films (The Revenant) and have to say the picture and sound quality it provides is truly awesome! I'm running it with a new LG Oled 65E8PLA so that obviously helps. The main review is very thorough indeed so I can't really add to that. Overall, if you can push the boat out, I'd say it's right up there as one of the best 4K players available at the moment ... you will NOT be disappointed! Cheers.
