Replaced my Samsung UN55F9000 4K LED TV with the Sony XBR55A9F 4K OLED TV this year and I honestly couldn't be happier! The picture on this tv is basically amazing! I use multiple sources from Dish Network, Toshiba HD-DVD, Panasonic 4K UN9000 Blu-ray and an 4K Apple TV. And it all goes through a Marantz SR-8012 11.2 channel surround sound receiver. By far the best tv I have ever owned!
