I am ready to upgrade my home theater receiver and need help from the experts. I would like to spend $500 or less to start with. I will be hooking it up to a panasonic DVD player, Time Warner High Def Cable Television, and an AE700u Projector. I would like to be able to run HDMI to the projector vs. component cables but this may not be an option for under $500. I already have nice speakers and a large polk sub with drivers. Any help would be greatly appreciated.
