[Elecraft] K3 Was - Which headphones for stereo cw work? Now - Audio Spread Spectrum

This thread reminded me of something that I read back in I believe the 
'80s. There was a circuit in which the CW audio was spread spatially, 
i.e., the lower frequencies were heard toward your left side while the 
higher frequencies were heard toward the right. The idea was that the 
brain could do a good job of separating closely-spaced CW signals if 
they apparently came from different directions. This would require 
stereo headphones to implement.

With the advent of DSP this might be a mode that Lyle could implement in 
the K3 if there was enough interest and if there was really an advantage 
in this mode.
