All the board changes do is improve low end response, which in my opinion is already more 
than good enough for CW and SSB work.

The 'filter' mentioned is not a peak or null filter, but just a lowpass filter to remove 
some very high-pitched DSP artifacts that bother some operators.

In my opinion, this replacement board is not something that everyone needs. I will 
probably order the filter sub-board by itself when it becomes available even though I'm 
probably too old to hear the DSP artifacts in question, but don't intend to bother with 
replacing the DSP board.
