So people can have a choice. Some die hard audio nuts swear up and down that there is a difference, but I sure can’t tell and every year when I get my hearing tested, the techs tell me my hearing is well above average. It is cool to see the indicator lights tell me I have DD-TruHD and DTS-Master coming into the AVR, but that’s about all I get out of it. I suppose why it’s so debated is that it’s new and up till very recently, no player or receiver could decode DTS-Master.
Video scaled and de-interlaced in the receiver or the display does make a difference. Some do it better than others, but most don’t do either well. For BR/HD 1080P source inputs, there’s no reason to mess with them at all. However, 1080i from cable / satellite can be greatly improved by a good video processor as well as 480i from DVD. 480i from satellite / cable….forget it.
