The point is.....most speaker systems are nowhere near a constant 8 ohm load. They have a varying impedance curve that can wobble all over the place owing to resonances, crossover alignment, driver inductance rise, etc, etc, etc.

Damping Factor, per-se, is not the issue, but rather those varying impedance loads causing frequency shifts when using amplifiers with highish output resistance. This can be somewhat significant and this is what accounts for subjective differences between various tube amplifiers relative to solid-state amps.

This is easy to experiment with. Just take your nice solid-state amp and add a 2 ohm resistor in series with the output. A sensitivity loss, obviously, but will hear a tonal balance change as well.
