Not sure what the confusion is about SACD.
You buy SACD players to play SACD discs and connect the RCA/XLR out to preamp or integrated amp. The only way to get DSD out is through HDMI/I2S cables of some blu-ray players and get the output to the DAC.
Last option is to rip SACDs as DSF/DFF files and lay them through the DACs using USB or I2S cables. You will never get DSD through coaxial unless you use players like Meitner which state the following:
- Up to 24bit/192kHz & DSD support over all inputs: USB Audio, AES, TOSLINK, COAX and Network(RJ45)
