Many high speed USB chipsets used in DAC's only accept 32-bit word length. In this case MPD/ALSA will zero-pad 16/24 bit to 32 bit. It's still "bit perfect" because none of the original bits are altered.
Note the "Formats" line in Audio info. It indicates your DAC reports S32_LE as the only PCM bit depth that it supports.
