Of course, this idea might not be so applicable to solid state power amps and might be better posted on a tube amp forum, but then again, maybe not. It used solid-state components.
Also, even if there's some reason I'm not quite on the right track here, shouldn't there be some way of providing a reactive load that mimics the reactance of the speaker via feedback?
A somewhat related idea I recently had was to use some digital means of providing a reactive load as well as vary the frequency response of a small-signal amplifier for a line out to use as an active-load speaker emulator. Perhaps an arduino board doing some frequency counting could do the job. You could then programatically change the behavior of the active load and frequency response of the line-out as you wish to mimic several different speakers.
