It has been said that the perfect amplifier is a "straight wire with
gain." In the last couple of decades even low priced amplifiers have
approached this performance so closely that it would be impossible to
hear any difference, even if it was perfect. This leaves amplifier
companies with a problem: How can they make an amp that actually
sounds different than the competition?

Make it worse, instead of trying to approach the asymptote of
perfection even more closely. It appears that that is what Wavac has
done--marketed an amp with performance that is bad in such a way that
some people will prefer its sound.

Of course a side "benefit" of such an approach is that it is sensitive
to just about anything, like AC line noise, or capacitances at the
output. Seeing how the output has spikes at 100KHz and so on, it is not
surprising that some loads and perhaps some cables may make the amp
oscillate. Some people call it very "revealing". Did anyone else notice
that the balanced input simply has one side grounded?
