In the pro audio world, we think of a 16 bit card as being more like 90 
dB, which is FAR more than we need as an audio interface for a radio. 
The 6dB difference is due to noise and non-linearity of the A/D and D/A 
converters at the low end of their range. As noted, the 24-bit and 
higher bit rate cards are appropriate for uses like SDR and LP-Pan.
