*** In fact, I seem to remember a feature of good audio amps - "damping 
factor".  It's basically a measure of
how low-low-low - much lower than the speaker impedance - the output 
impedance of the amp is.  A good damping factor
helps control inertia effects in the speaker cone - helps give you 
"tight bass".
