GR! wow I just checked the 1600. It doesn't upscale 480 to 1080 as I was thought it's the same with 2600 with a little less power, but it is not! Anyway JP was right. My experience with the 2600 is working really great in term of upscaling. If sending s-video from satellite receiver to RX-V2600 and HDMI out to TV , then you get upscaling quality as close as HD rather than the 480 mode in regular tv channel. My HD 65" sony display at the best quality as I've ever seen at 1080. Also, the quality color of GUI screen much nicer too as you press the button. In addtion with audio, I'm just crazy about this 2600 that really help my video setup in perfection for my current gears.
