Amplifier Output Impedance – It Matters - Samma3a Tech

As I understand it, the damping factor is the ratio of the impedance of the headphones to the output impedance of the amplifier, and the general rule-of-thumb here is that you’d ideally want the amplifier’s output impedance to be no more than 1/8 th of the headphone’s impedance. So, if you have a set of headphones with a 32-ohm impedance ...

other power amplifier. Keep in mind the output impedance is an abstract term as far as output voltage and current capabil-ity are concerned. To demonstrate the effect of output impedance when model-ing, use the highest and lowest expected values. The results will verify that output impedance plays an insignificant role in power amp performance.

It is much simpler to connect the amp output to GND and inject an AC current in the amplifier output, for example using another amp and a 8 ohm resistor. The voltage at the amp's output gives the impedance, an you can also visualize it on a scope, FFT it, whatever, to reveal all sorts of gremlins (crossover distortion has nowhere to hide).
