OP does not provide enough information. If the choice is just between the two processors and acoustic room correction is wanted, then It's probably the Anthem, because ARC was a major bug in the Cary 11a and likely to be in the 12 -- the Cary 11a manual recommends a tape measure and SPL meter. If OP's sources are discs, computer, and cable/satellite, then Oppo 105 analog direct to amps might be a better choice than either processor, because it can do lossless codecs, speaker configuration, bass management, volume control, and so forth. It doesn't take analog input, e.g., from a from a phone stage, but it can switch among digital sources.
