Regarding:
http://www.mines.uidaho.edu/~glowbugs/clipper.htm

Aren't these diode clippers inherent distortion makers?
When you clip AF you make unwanted harmonics, which must then be filtered out. The 
resulting audio does not sound exactly like the original.

Some of us who have owend Johnson Valiants fixed the awful sounding audio by BYPASSING a 
circuit almost exactly like this one!

On the Valiant, even if you tuirned the clipping control down to ZERO, it still
introduced some raspiness. The change to hi-fi by removing the two tubes and
then running around the circuit with a 0.1 uF capacitor was such a dramatic improvement
that I was sold on removing all clippers!

It seems to me like a quality compressor-limiter device such as is used in
recording studios or for live sound wouldgive you a vastly superior result than a diode 
clipper.

Comments?
