Skip the Anthem, for two reasons. It doesn’t handle 2 channel surround correctly and the room correction isn’t all that. It doesn’t do a great job of integrating the loudspeakers and doesn’t allow you to manually adjust either. The latter is only useful for EQ geeks like me who know exactly what they want.
Consider the Marantz units with advanced Audyssey long before Anthem. Haven’t heard NAD.
Also, maybe it's just me but previous gen Anthem processors sounded better, plain and simple.
