    If the SB Audio Player PRO has an HDCD decoder, then you don't need to use the HDCD DSP when ripping.

The HDCD DSP in dbpa and the HDCD playback component in foobar2000 player are simply "reverse engineering" to get something close to what the HDCD capable player would use when playing. And to do this the file has to be upconverted.
