Why don't higher end amplifiers come with a separate power chassis?

Now it's car audio, two entirely different sets of parameters.

I believe early perfectionist audio systems were derived from equipment used in moving picture show houses.  There has been much evolution since.

Yeah.

Car audio is responsible for the ability of speakers to handle highpower.

Right

Small drivers, that can handle higher power came about when higher power solid state amps became a viable option as opposed to the lower powered tube amps that came before that necessitated big, high efficiency drivers in big boxes.

Got nothing to do with car audio…

True. Like the home speakers from the late 1940's early 1950's. See below:

Why do amplifiers come with such cheap power cords.  The power cords they come with might cost $5.
