On this curve (B) we can clearly see that intrinsic symmetry due to the matching of the two
halves reduces the distortion by a factor of 10. Supersymmetry (D) creates a more perfect
match, and results in an additional reduction by a factor of 10. However there is essentially no
difference in the distortion figures at the output (C) of each half of the circuit considered alone.
Supersymmetry does not work by reducing the distortion per se, rather it works to precisely
match the two halves of the circuit and lets the balanced output ignore the unwanted
components. As long as the two halves are matched, this performance tends to be frequency
independent, and does not deteriorate over the audio band. With mid-level distortion figures
on the order of .002%, this is very high performance for a single balanced gain stage.
The following pages include a copy of the cover page of the patent, a diagram of the
appropriate AC power outlet, a typical distortion curve of the amplifier, a list of specifications
for the amplifier, and where to reach us.
