I have tried to so some research to clear up the controversy surrounding the "day and night" claims that have been made for the LOD.
The chip used in the Fuze is the AMS 3525. Here is the full AMS 3525 data sheet
I have clipped out the specs for the DAC input to line output and the DAC input to HP output for easy comparison:
The outputs are .035 apart
The SNR is slightly better on the HP output by 2 dB
The DR is slightly better on the HP output by 1 dB
The THDs are exactly the same
