In Direct modes (no Room Correction, DSP, EQ, etc), you won't hear a difference between Marantz vs Anthem.
If you do use Room Correction, some people will say they prefer Anthem while some prefer Audyssey. No Room Correction software is perfect. Everyone is different.
I have played with both Audyssey & Anthem. I don't like any room correction.
I prefer Audyssey just for the Dynamic EQ function. I like Dynamic EQ for my Subwoofer output.
I love my Denon AVP-A1HDCI pre-pro + ATI AT3005 amp combo.
