I'm not exactly a professional in this area, so I have some questions:

1. What is so special about a harmonic that it could be heard @ 42kHz whilst
a Fundamental couldn't?  Does the Harmonic affect the lower frequencies
in some way through interaction?

2. How many amplifiers have you seen that even claim to respond to frequencies
above 40kHz (much less 20kHz)?
