That one's got me curious too.  I'm particularly fussy about DSP 
noise reduction, and there are very few that I actually like.  The 
one I use is made by Michels Engineering in Germany, which provides 
an excellent degree of noise reduction and doesn't distort the audio 
as severely as many others.  For me, that distortion interferes with 
my ability to pull a signal out of the mud, and most of the DSP noise 
reductions work best for me in the "off" position, as far as 
readability goes.  The Michaels one, OTOH, has no impact on 
readability at worst, and often a modest improvement, as well as 
excellent noise reduction.  On very weak FM signals (ideal for SO-50 
:) ), the readability is dramatically improved, and the DSP can 
almost act as an FM voice activated mute.
