So what do you think it is that makes damping factor
*unimportant* ?

It's not that damping factor isn't important, its that it is an odd way to
express the underlying physical parameter which is amplifier source
impedance.

For openers, damping factor isn't an amplifier parameter, its a parameter
that is also strongly dependent on load impedance. Unfortunately the
underlying physical parameter remains pretty much unchanged, regardless of
load impedance.

With good modern amps, the amplifier's damping factor is generally so high
that it gets swamped by all sorts of things including voice coil DCR and
speaker wire DCR.

It means a lot more with tubed amps.


Which is probably why it was ever expressed as a value at all. When they
came up with it, tubes were dominant, then came good more accurate, less
volatile, transistors. :-)
