8bit sound is poor but there is no real 32bit soundcard.
this 32bit stands for the data communication between soundcard and pc.
cd-audio is based on 16bit . there are 65535 possible steps and voltages to
studio equipment today is mostly based on 24bit technologie and so 18bit is
also a standard resolution for e.g. adat-recorders.
i dont't think that you realy can hear the nasty steping on cd players,
maybe it's a bad da-converter but there a no steping of a waveform in the
analog vonverted signal. the da-conversion is followed by an analog filter,
and if smoothed by this, so there is never this step in the waveform.
