Hi Deane - for what it's worth. I think for most non-critical (non-contest, non-DX) users, the K3 standard 2.7 kHz SSB filter does a good job for CW and SSB modes. The K3 DSP software allows you to narrow the bandwidth for CW to 500 Hz or less. The DSP works much better than the Yaesu and Icom (IC-746 -- nice radio in many ways) radios I have used recently in my shack.
HOWEVER -- the additional , narrow filters ( I have the K3 400 Hz filter ), do make a difference on CW when contests rule the band. I don't think you'll go wrong with a K3 with whatever configuration you choose now -- you can easily add filters and options in the future.
