No, I doubt you would realize any meaningful sonic improvement by switching your Yamaha receiver for another receiver. Yamaha receivers are pretty good.
However, you could realize a heap of meaningful sonic improvement by taking that $1K-2K and upgrading to the 804S speakers. Your Yamaha would drive them just fine. Also a $500 DVD player need not be a weak link, in video or audio. For example the Denon 2910 is a terrific player.
