Anything as " fast" as SPECTRAL gear?

Omsed. Hope you feel better now. There,there.

Psag. Our departed Harry Pearson gave them all the guide. Be part of a system reproducing the sound of orchestral instruments as heard live.

Wow, very interesting reading in this post. Better than most!
I don't know what "Fast Gear" is. I would steer away from such terms.
Low noise, low distortion. That's what sounds good.
As for transient response, that's what it's all about. Laplace showed that awhile ago.
Steady state is dead when it comes to music!

Sorry, my mistake.
I meant Fourier.
What a dope I am!

@Mapman ... I seem to recall Ralph (Atmasphere) posted comments some years back about the impact and import of high damping factors (DF) on woofer control. DF, of course is simply speaker impedance at a particular frequency (usually in the bass range), divided by the amp's output impedance at the same frequency. 
I'm just enjoying warm brandy and reviewing this old thread--and this statement confuses me. If it's correct how can an amplifier have a DF in its specs?
