If you are German speaking, here's another one, adding to @tmukh 's question about the dac chip credibility:
You can see it actually says ES9017 DACs!! It is for the Marantz Cinema 30, but in the past the X6400H through X6700H shares the same DAC board with the SR8012, SR8015, AV7704/7705.
Enough said, based on multiple collaborative sources of info, I feel comfortable the AVC-X6800H and C30 uses the ES9017S, that has much better SINAD specs than the previously used PCM5102A. It is even comparable to the AK4490 used in the AV8805A and AVR-X8500H, and better than the ES9010 K2M used in those since the AKM dac chips shortages started in the spring of 2021.
