Re: what are the real reasons for upgrading a processor?
Unless you are using an HDMI Y-cable or HDMI distribution box to get audio to your Rotel and video to the Kuro, you are missing out on the best available audio. If your Rotel can process MCPCM, you can get away with only getting a new player for hearing the new codecs (provided you pick a player that can decode the new codecs and send out the signal via MCPCM.) IMO I believe the new codecs are worth an upgrade. You really need to go to a dealer that will A/B the new codecs vs. the old ones for you so that you can hear the difference which is noticeably better.
