[Elecraft] Compare: K3 to Collins S-line receiver

[Bob McGraw K4TAX]

There is a clear and accurate technical reason.  Musically pleasing to 
our ears is the difference between an audio signal containing 2nd or 
even order harmonics vs. a signal containing 3rd or odd order harmonics.

Even harmonics (i.e., second order harmonics) are considered to sound 
fat and warm, although they can be muddy and soft sounding as well. Odd 
harmonics (i.e., third order harmonics) are considered harsher and 
edgier sounding.  A pure square wave gives only odd harmonics.  A pure 
sawtooth wave gives both even and odd harmonics.  A pure sine wave has 
no harmonics other than the fundamental.

And now you know the rest of the story.
