Replacing your Anthem with something comparable isn't going to be cheap. NAD T 758 has Dirac live which (arguably) is said to be better than ARC. The downside is it doesn't have alot of HDMI inputs. Alternatively, you can go with a Denon AVR-X3500 which has Audyssey XT32, dual sub eq, pre-outs, plenty of HDMI inputs and plenty of features.
