[Elecraft] The amp I would like to see Elecraft build.

FALSE.  CW is 100% modulation of a carrier by a rectangular wave, and 
that modulation, like ANY amplitude modulation, produces sidebands, 
which will excite distortion in a non-linear amplifier.  I don't know 
enough about Warren's Pure Signal system to know if it could be used on 
CW. IM sidebands can be clearly seen in the display of a CW signal on a P3.
