Sounds like you have a great home theater system Bill. With the exception of souce components, I can't think a reason to change the Speakers and Amp. Even the Pioneer acting as a pre-pro is a solid link if you do not need HDMI 1.4 and it sounds like you don't - you're happy with your projector. Further, the Pioneer uses advanced MCACC as do the newer Pioneer Elites so no advantage here either.
So perhaps the only thing is the source. If you like music, upgrade your BluRay/DVD/CD player to get better DAC's for CD playback and utilize the players analog outputs. If you dont care so much for music, don't change a thing as you in very good shape right now.
