I'd like to suggest that amirm use the same SMPTE IM distortion versus output level in his amplifier evaluations that he uses in his DAC evaluations.
Measurement of harmonic distortion at 1KHZ reveals very little about an amplifier's quality of design or listenability, but the IM distortion measurement
separates the wheat from the chaff.
