Why is there a ‘network’ DAC onboard then? According to one of your own postings in the initial 4700 review thread you mentioned how Marantz does it:Not true unfortunately! "network", if using the main zone, still uses the AK4458, the PCM5100s are used for zone2 and 3. Pretty sure when Amir tested network, he was still using the main zone. If he measured the same on Z2, then he would have tested the PCM5100 that is a 2 channel DAC chip.
Denon and Marantz has been using the AK4458 for all channels but for the HDMI and optical/coax inputs only
The THD+N and DNR specs are 115 dB and -107 dB.
The PCM5100 is for the network and zone 2/3 etc.
Also the pictures of the internals in that thread show this third PCM5100. What is this (network?)DAC doing if not digital->analog converting from Apple Play (Apple Music) to Main Zone? In any case, a lot of measurements ‘User 22’ performed in the Denon DRA-800H review also showed the PCM5100A outperformed its ‘max’ specs touching acceptable mid-tier SINAD scores.
