Connecting the Stellar gaincell DAC to external Audio interface via I²S

Hello from Germany :slight_smile:

Just purchased an Matrix Audio X-SPDIF3 audio interface to optimize my connection between PC and DAC.
My aim is to use DSD via Audirvana Studio.

There are 4 differnet IIS schemes of HDMI ports (plugs?) in the Manual of the Matrix SPDIF3 (A,B,C,D) The device has the option to set jumpers. Which is the one that fits best on my Stellar DAC?
Anyone else uses a matrix device to connect an PSAUDIO DAC here?

Best regards,
