Dynamic range is part of the story.  Look at MDS values for those high DR 
SDR receivers.  High DR, BDR and IP3 figures are of little value in and of 
itself if MDS isn't also reasonable.   100+ dB DR does not guarantee good 
MDS figures.

Every SDR receiver I've seen to date either needs RF pre-amplification (and 
all the warts that come with it) or better (and not yet available) 
performance from a demodulating sound card to achieve MDS numbers 
commensurate with many of the traditional architectures, including the K3.
