Matrix Audio X-SPDIF 2/3 USB Interface

Are these units compatible with PS Audio Stellar gain cell DAC/preamps i2s input or will the dip switches need to be changed.
Thnks

I use my X-SPDIF 2 with the SGCD and it worked out of the box

Appreciate the feedback, thnks,
Any input on the sound quality with the Matrix vs usb into SGCD, thnks
