As a very satisfied owner of a AVR-X6200W (last year's model), the successor model X6300H should be a very attractive AV Receiver for anyone wanting a quality Dolby ATMOS and DTS-X 7.4.1 (or 7.4.2) setup. Since the new model has a full complement of 11 amplifier channels, no additional amps are needed, unlike my 6200 which required me to use 2 channels of external amplification. Perhaps the best news is the MSRP on the new model as the same as last year's model that it replaces.
I am loving my new 7.1.4 Atmos / DTS:X setup with the 4300...my first Denon AVR...thanks again JD! The HEOS speaker was icing on the cake...
