Of course, the KX2 is *not* a superhet, it is a full SDR. If the "IF" were at a higher frequency, the VFO would be further away from the signal frequency - by the frequency of the IF.
I must disagree. All the digital processing takes place after the quadrature mixers. Up to that point, it IS a single conversion superhet, but with two mixers with quadrature outputs. The same is true of the KX3, though it can be operated as a direct conversion receiver, which is simply a superhet with a zero frequency IF.
This is in no way meant to disparage the design of the KX2 or KX3: They are truly excellent radios.
