I have had my K2/100 with KDSP2 for 4 months now and almost never use the 
DSP.  The stock filters in the K2 seem to work just as good, and often 
better, than the DSP filters but that is very much a matter of taste I 
think.  I operate only cw and my comments apply only to cw mode.

I like the DSP 'de-noiser' but I live in a pretty quiet environment and 
rarely think to use it.  In a noisier environment it might be worth the cost 
of the DSP2 all by itself.

As you can see this is a very incomplete response to your question.  The 
answer depends a lot on your preferred modes and environment and I will be 
watching to see what others say.  The bottom line for me, though, is that 
both the DSP or KAF2 are minor enhancements to an excellent  receiver.
