According to the K3 Owner's Manual, the K3 uses a 24-bit ADC. From the
schematic, it appears to be the Burr-Brown PCM1804DB, a very nice
part.

Interesting. Can you explain how exactly you define "DSP horsepower"? Is
there evidence that K3 does not have enough "DSP horsepower"? Are you sure
the current K3 DSP software used full potential of the TI DSP chip?
If we talking about processing, somewhere I heard that KX3 use 24 bit
sigma-delta ADC. Now that is something new with potential. If I remember
correctly, the K3 uses 16 bit codec. I am a little skeptical that 24 bit SD
will give measurable advantage over 16 bit ADC in ham radio application. I
guess at some point it will be measured.
