What Redditors Say
Best praise vs top criticism for Panasonic DP-UB820
Best Praise
+76 pts“The ~$200 players are the UB420 and UB450. - The UB420 has the HDR optimizer, which is useful for pre-tonemapping HDR video to be played on a projector. - The UB450 has Dolby Vision support, which is useful for OLEDs and higher end LCD TVs. The ~$400 player is the UB820. It has both the HDR optimizer and Dolby Vision. It's pretty much the best mass market Blu-ray player you can buy before you get into kinda crazy pricing. The $1000 player is the UB9000. It is basically a UB820 with a metal chassis, nicer remote, and quieter motor. It also has a nicer DAC built-in if you're using the analog outputs for some reason.”

+15 pts“So as an 820 owner, I have to know: are the menus and general remote response on this snappy? There really is some special sauce in the UHD tone mapping, but it's so slow I find myself not using it. Id shell out for the 9000 if it was fast.”
