[Elecraft] K2 CW monitor

[kt5x at cybermesa.com]

This may seem odd, but the main reason I have not yet sold my FT-1000MP in 
favor of a second K2 is the CW monitoring.  The CW side-tone in the K2 began 
with a terrible sound.  Various mods improved the sine wave attritubes, but 
it remains relatively poor, harsh at the make and break, and in between I 
don't know how to say.  In comparison, the MP side-tone has a soft rise and 
fall, while the tone in between is rich in overtones, very pleasant to 
monitor.

Why is the K2 side-tone so lacking?  Could a better one be a mod?
