The PCM1748 is a single-ended, voltage output DAC, whereas the PCM1794 is a differential current output DAC, so the Passive Output Stage is not compatible with the PCM1748. If you want to eliminate the op amps from the signal path following the PCM1748, you will have to use a coupling capacitor (to eliminate the considerable DC bias) and then either use this output directly or run it through a 1:1 transformer. The PCM1748 is a low cost DAC, so it doesn't provide the higher end flexibility of the PCM1794 in terms of audio interface.

To ease your way into the RAKK dac world you might want to hang around here until a Mk I comes up for sale by an upgrader to Mk II. It happens from time-to-time.
