Emotiva UMC-200. As long as you don't need legacy video inputs (component, composite) or analog audio inputs this would seem to be a wise choice. $599 with a 5-year warranty...
Eyrdkill: Interesting you should bring this up. I'm in almost in the exact same situation. I have a 10 year old RSP-1066 that still sound fantastic particularly for music and DVD concerts powered by an RMB-1085). I don't use any HDMI on the RSP but plug my blu-ray player directly into my TV using HDMI. I too want to upgrade (have the upgrade bug) to something brand new but a new Rotel RSP-1572 is out of my budget as well. I'm seriously considering an Integra DHC 40.2 surround processor. On-line reviews are mostly excellent and new is $1,200.00. My high end audio store carries this line as well as Rotel so it has to be decent. I still have some questions that I can't find the answers to on-line so I'm going to have to demo it soon. So if you purchase a new plasma TV, why would you need a new processor? To me the less cables going back and forth between your TV, receiver, cable box, DVD player, etc the better. Do less harm by minimizing cables and lengths. Let me know your thoughts on this. Good discussion.
