It's the other way around: Adding resistance in the

a power amplifier is the reciprocal of output impedance.

Bob, I wasn't aware of that definition.
I was thinking of http://en.wikipedia.org/wiki/Damping_ratio
rather than http://en.wikipedia.org/wiki/Damping_factor

Is there an understanding of why high "damping factor" would be good?

Jont's findings suggest otherwise (I believe he's saying the current is typically more relevant than the volage).
