I prefer Anthem to Marantz, a little cleaner and hits a little harder I think. Best of all is ARC is better sounding than Audessy. Anthem is brighter and I like that, but keep in mind that you're going to use room correction anyway. That should take care of it unless you plan to listen to 2 channel without correction. In that case, Marantz may well be better if you're concerned about too much treble.
I just upgraded from MRX-710 to 720. A little more power than 520 and has atmos. Good luck! Dan
