Output Impedance in the sub milli-ohm range resulting in a five-digit Damping Factor.

Another takeaway from this graph is the close spacing of the traces -- all within about 0.1dB of each other. This indicates the amplifier's very low output impedance across its operating range, and its commensurately high damping factor. Although it's not shown here, when we measured the output impedance and calculated the damping factor with a 4-ohm load, we got a very high 1600 from 20Hz to 4kHz -- and from 4 to 20kHz the damping factor rose even higher, to almost 2000.
