This part is pure BS!!
If you look inside the comparable Marantz (e.g. SR6014, 7013 and Denon (e.g. AVR-X4500H) receivers, and the available service manuals, you will see the following similarities:
- Same audio signal path parts and circuitry from input to output except Marantz's has the HDAMs that acts as an extra buffer in the pre out end, yet there is an Op amp of average quality right before the power amp input, for the front right/left channels. You get that same opamp in the Denon's since the AVR-X3600H and X4500H.
- Identical power amp section, I mean identical to the point even the bias voltages, rail voltages are the same.
- the power supply block diagrams and schematics are the same, except the 6000 series has a slightly larger power transformer but that's loosely based on their silly power consumption specs and bench measurements by ASR.
So what are the so called premium parts? The only thing I can see are the gold plated connectors, that are not found in the Denon 3000 and 4000 series.
May be the cinema series and the 2022/23 Denons have more differences but based on available info so far, I doubt that very much.
Regardless, how do you get those different sound signatures when the hardware, circuitry are the same, and measurements show distortions, noise, crosstalks, frequency response, damping factor, linearity, DR, power outputs are all virtually the same?
Do their soundmaster really tell their designers to tune the sound, by trial and error adjusting resistor, capacitor, inductor values, and if so, why would the bench test results show the same as that of Denon's. The only difference is in the frequency response graph for the digital input test using 44.1 kHz sampling rate. In that graph yes Marantz has the characteristic roll off from just below 10 kHz and dropped gradually, by about 2-2.5 dB by the time it reached 20 kHz. That seemed to say that's really what's behind the different sound, as in the AV10, there is the option to choose the different DAC output filters provided by the ESS DAC, many external dacs provide the same kind of options.
If you look at the FR using analog inputs, or digital inputs but using higher sampling frequency such as 96 kHz, the curve will be flat just like Denon's.
So again, this warrm sound vs precise/clear sound talks are pure (okay may be 99%, to allow for people with bat's ears playing digital contents of sampling freq below 48 kHz) BS.
Denon has a soundmaster too, wonder if he's the same one for Marantz, if not, you get paid more??

if Marantz did use premium parts (I mean aside from gold plated connectors and the added HDAMs), and different circuitry, how do they explain the price premium for the Marantz vs corresponding Denon's
Do they think AV consumers in North America are silly enough who would fall for the Masimo/SU marketing BS?
