@rolee910 oh yeah I just looked closer. Then you need to get a coaxial SPDIF cable or use one that comes with the device to link to the coaxial SPDIF input on the back
Toslink is historically capped at 96kHz even though there are modern toslink cables and implementations that can do 192kHz.
So get a coaxial SPDIF interconnect and connect between the coaxial output on the CD player and the coaxial input on the DAC
