But, if this is the issue, you can tell because the distortion character
will change with the load impedance. You can see it on a scope and you
can hear it change as you add shunt resistances to your load.

Yep. More current makes this better. But better yet is some gain in
front and an external feedback loop that comes from the emitter pin.
Op-amp anybody?

No need to go that far, the simple Ring of Three circuit family can be found
in all sorts of applications like that. Gain is cheap in the solid state
world, so it's frequently to your advantage to trade it for linearity.
