Actually, not to worry about Anthem, they are just the electronics division of Paradigm speakers, both long established Canadian companies been around for decades. In addition, as already pointed out, Anthem's room correction system "ARC" is regarded as about as good as it gets. Whenever it is updated, I would also strongly consider what is currently model AVM 60, Anthem's 11.2 Pre-Pro.
FYI, NAD is the electronics division of another Canadian company Lenbrook Industries makers of PSB speakers, its HO located directly on the opposite side of town from Paradigm/Anthem. Also been around for decades.
