Yes, you could use the combo input board and differential line stage kit with your DAC. You would have to change the I/V resistor values to account for the lower current output of the PCM63, but that's no big deal.

Ok, thats great news, so how do I wire the combo input board to my dac.
Do I wire it direct to the output pins of the PCM63 and bypass the filter and i/v resistors, already there on my dac. or do I wire it to the output of the dac after the filter i/v resistors.
" You would have to change the I/V resistor values to account for the lower current output of the PCM63, but that's no big deal."
what value resistor would I need?

  You would wire directly to the output pins on the PCM63, deleting your existing filter and I/V resistor. For 2vRMS output, you would need about 15K by my quick calculation. This resistor is on the secondary of a 1:10 transformer rather than at the DAC; that's why the value is so high compared to a resistor used directly across the DAC's output pins.

    Hi!
    thanks for the info. could you please explain how you calculate for the I/V resistor. I am new to audio transformers, so would be glad for some help here.
