If you live in the city, I wonder if you might prefer either the KDSP2 
or the KNB2 over the KAF2.  I live on a busy intersection in a big city, 
so 've got pulse noise more often than not.  The KNB2 takes it out 
pretty well.  I think the KDSP2 will deal with pulse noise, also, but 
the KAF2 alone won't do any more than dull the high frequency component 
of pulse noise.

Also (but this is probably just me), I find that the KAF2 blurs the 
edges of the dits and dahs, making signals harder to copy rather than 
easier.
