Play any action scene in both to find out which one is better. Marantz though excels via its HDAM circuitry by giving clear vocals and details in midrange, denon excels in chest slam punch. Marantz has better musical signature. Though we Indians miss out on lots of other amps like in Europe n US, we get only 4 brands to toy with. Now slowly down the line most brands are owned by sound united, the difference between their sounds shall reduce as AVR. With atmos channels increase in US , many are either going for high end avr or better still processor +amp combo. For us we have to also see , while buying, factors like dealer and our flat /house size and budget before we get either of them. Do remember sound also depends on speaker and it’s sensitivity and power it needs and how well it adjusts to ur den (read acoustics) . So before u decide at dealers demo room via their high def sound track (which I did ) , do listen in a friends house a regular movie or song and then go for what ur ears say.
