I originally asked if anybody sold a VCO with undistorted sine outputs. In summary here
are the replies I got:

1 - Manufactures claim they can spec any wave with rounded peaks as "Sine". Even if you
can clearly hear even harmonic distortion - any roundish looking shape is a close enough
to be called a Sine.

2 - Analog vs. Digital religion states that analog must always remain imprecise because
that is its character. We don't want a clean analog wave with no added harmonics in our
system because that would make it digital.

3 - Finally the topic police posted their overall disapproval of this discussion. Even
banning members was suggested!

So I learned if you want a real sine wave (as defined by Fourier), get Plan-B Model 15...
