Probably best to post in the 'Discless Circle' vs. in the Starting Block. According to the manual "The SPDIF outputs include one each of COAXIAL & OPTICAL.
• When playing PCM files of 16 – 24 Bit, 44.1 kHz - 192 kHz, digital output will match the
source. If using TruBit™ Upsampling above 192 kHz, there will be no SPDIF digital output.
• When playing DSD files, there will be no SPDIF digital output."
