Yes, I can confirm that the R60 and R61 resistor positions are empty on the Terasic ADA board, at least with the CIII starter kit. Putting a 0ohm resistor on R60 ane removing the transformer does indeed give you single ended (DC- coupled) operation at the DAC with very little impact in terms of additional noise.

However, if you require also a single ended input, please note it is much more complicated to achieve this at the ADC end and I have not yet been able to do it.
