I'd be more interested to see how it operates at frequencies other than 1k. The way their signal looks, at 10k to 20k their harmonic distortion would go through the roof.

You are looking at a version of the amplifier aimed at voice for cell phones. Depending on which screen shot you are looking at, it is either 10 kHz or 15 kHz, with the amplifier clocked at 166kHz. Contact me at tlawson@cognipower.com, and I will send you a screen shot of a 20 kHz sine wave with the same amp being clocked at 1 megahertz. A very small notch filter removes the carrier frequency quite nicely.
