Those are certainly valid settings for one way of operating. I choose to 
keep K3 RXEQ set flat for both modes. My reasoning for CW is I'm mainly 
a contester, so I want to hear off-frequency signals calling me at the 
reduced levels that result from the IF bandwidth I've set. On SSB, 
because I'm already limiting the LF response by setting of the IF 
bandwidth, and high frequency peaking tends to increase the audibility 
of splatter.

But the important point is that there's no single setting that is 
"right" for everyone, or for every style of operating.

I do things differently with the KX3, because the audio output stage is 
current-starved, so it doesn't have much headroom. So for the KX3, I 
roll off the three lowest bands on both modes (max cut), leaving the 
others set flat (no boost, no cut). I would suggest the same settings 
for the new KX2.
