I currently have an HK AVR520. I was looking to possibly upgrade, because I want to use it now for a whole house audio source.
My HDTV has only component HD input. I would like to know if today's receivers ($600 price range) would be a noticeable improvement in picture quality when going from the 520's 50mHz switching to 100mHz I see in some of the newer ones? In fact, are there substantially better offerings today at the same price level as the AVR520 was then? I think I paid 450-550 it in '02.
Thanks for the help.
