Having had the Adcom in my system for an audition (friends unit) and owned an AVM2, AVM20, AVM50, AVM20-HD and a D2, I'd go for the Anthem. The AVM50 also has a broadcast scaler built in and the new AVM50v decodes the new HD surround formats. Of course, the Anthem is twice the price of the AVM50, which isn't a fair comparison.
