I'm assuming you ran the soundcard calibration, which uses the analog connections. If you keep that cal file and use the SPDIF output you will be compensating for low freq roll-off in the analog output stage which is no longer there, hence the boosted displayed results there. If you have not run soundcard cal you will still see a boost (of half as much) at frequencies below the point the analog output's low feeq response starts to roll off.
