There are DACs that will accept the DSD input from SACDs, but I am not sure that the Marantz is capable of outputting DSD from it’s digital output. I think you would need a different transport than the Marantz, and a different DAC than the Azur, which wouldn’t be able to accept it even if you could output the DSD layer.
Play the Marantz by hooking the analog outputs into your preamp and enjoy.
