If we are to compare base on subjective measurements, may be we should start by comparing their design philosophy.
Marantz marketing is very good at what they are doing (or writing..). Anthem basically says theirs don't have sound signatures.
From Anthem website:
that matter the musical score within a movie soundtrack. Accurate for one means accurate for the other.
Marantz basically says the opposite, and they are smart to give potential fans the reasons, such as the HDAMs, gold plated rca connectors, use of their "soundmasters" etc..
Those who are not technically inclined would buy into the "reasons" provided and would therefore likely to hear the kind of warm, musical, or whatever "sound" they Marantz skillfully planted the seeds in their heads.
And, on Marantz HDAM
That reminds me of PS Audio, Audio Quest, Bose etc.
Okay Marantz, I am only joking and have supported Marantz over the year, so please don't write me up.
