Hi, marcmccalmont!

I am not familiar with Audio GD DAC. According to the description "3.3V" on the picture you showed, their I2S seems to be CMOS Level compatible and single ended. As you may know, PS Audio I2S interface is based on LVDS with differential.
I'm afraid that you might have no good result.

In general, you need such a level converter from LVDS to CMOS;

(This schematic shows examples of PS Audio type transmitter and receiver designed by Fidelix company in Japan. The receiver includes an additional I2S isolator.)
