ASR reviews garbage. I would not care for anything they say. I owned an AVM60 for 4 years. I traded in for Marantz AV7706. About 2800 from local dealer. Before the price went up I think. It had a hum in my system where Anthem did not. Went back and paid another 600 and got AVM70. Hum gone. Both sounded about same in my system. The Marantz gui is faaaaar better than anthem. I think I prefer arc sound in the end. Also the cardboard rocket to hold mic for a $3000 processor is ridiculously cheapo move on Marantz. Anthem gives real mic with calibration file and tripod. Comes with toroidal transformer. Hence no hum. Go for the 70. Search for a deal and grab it.
I have never heard Arcam but historically very good stuff.
