some processors can take an SACD digital stream over the HDMI cable and decode/process it. That being said, I think the Oppo sonic signature is somewhere in between the Marantz and Yamaha.
The Marantz is excellent with a large power supply but voice very slightly warm and soft rolled off highs. The Yamaha will be sharp with clean highs, but may not have as much body/bass strength. The Oppo analog output is somewhat tiny bit warm but still with full resolution.
