Eric,

Those are very good examples and reflect my experience with the KDSP2
as well, although I haven't had much opportunity yet to use it on SSB
(I just finished the KSB2 yesterday). 

There is practically an infinite combination of available settings for
the various features of the KDSP2, unlike much of the competition which
gives you perhaps a few pre-set values.  Although the default settings
are not bad, I suspect that most people will want to experiment a bit. 
The manual lists all the default values so it is fairly easy to return
to the starting point, if desired.  I have been keeping noise reduction
on in CW mode (it's easy to mistake the noise reduction for a dead
band!), but only use it for SSB when conditions dictate.

Do you recall what settings were used in capturing the demo audio?
