I have heard, from a local ham who tried one, that for a CW operator

If the DSP is killing the induced hum, then you are giving up some of 
the DSP's dynamic range. If you could do some shielding or balancing to 
get rid of that hum using traditional methods, so that the DSP does not 
have to do that work, then the DSP might work even better.
