Keithley 2015 THD measurement on Leak Stereo 70 & NAD 3120

I demonstrate the sine wave generator and THD (Total Harmonic Distortion) function of the Keithley 2015. Then I take some measurements on the Leak Stereo 70 & NAD 3120. These readings simply serve as a metric to be able to compare amplifiers - they certainly do not indicate which amplifier will sound best (my favourite has the worst figures) and you certainly wouldn't buy an amplifier because of its THD figures.
