The biggest henderence is taking the time to figure out exactly how to do it. Does it have the capability, it's supposed to, but I have to go in and reassign a bunch of analog inputs. It's more difficult than it sounds. Although I can navigate the menu it's not the friendliest set up and the manual isn't much help.

My Samsung is lacking some of the HD audio decoding. What is the difference between Tru/MA and uncompressed 5.1? I have a HDMI switcher now, it would make sense to try the MC before upgrading. I think I got restless over my processor when I had an optical input go bad. The coaxial DD/DTS sounds very good. It would be interesting to hear the difference though.

Also, the Marantz had a few other features I wouldn't mind having. On the other hand there is that fear of getting something that might not sound as good as my Primare.
