I've once seen a chart explaining the usable dynamic range of a compact disc in
professional use (with 16 bit depht). What I remember is :

1)  On the upper end of the theoretical 90dB range they have to cut off 10dB as
a clipping reserve, since digital clipping would immediatly destroy a whole
recording.

2)  You cannot really use the lower 30-40dB of the 90dB range, since distorsion
becomes too high (up to 40% in the first 10db range, as far as I remember). The
reason for this is the decreasing resolution of the sampling device at lower
input levels.

Thus the reamining usable dynamic range of a compact disc doesn't exceed
40-50dB, that is still a lot but can be outperformed by analog recordings.
