BD players should be outputting HDCP 96/24 sources over S/PDIF as 48/16.
The Marantz user selector for output sample rate is just to achieve compatibility with external devices that cannot handle 96/192 kHz. It will not override HDCP requirements.
ETA: Tried some 96 kHz DVD-A discs in the Oppo, and even with the PCM sample rate limit set for 96 kHz, it outputs 48 kHz from the S/PDIF while outputting 96 kHz from HDMI, at the same time. So I guess the issue is not silence from outboard DACs, but sample rate (and maybe bit depth). Even with 48 kHz source material, the CB-IIIHD upsamples to 96 kHz and runs all post-processing and the DACs at that rate. Taking that back to 48 kHz to feed the external DACs will indeed still present audio. I guess it will all become clear(er) very soon.
