If you want to run the drivers hard, to keep up their speed, then maybe try as low as 30r.
Yes, tiny changes in driver current result in enormous changes in output current. Your sim should show that, if you apply a signal and monitor the IC of both driver and output.

learn how the circuit operates from first principles (pencil and paper), or use the sim to investigate the operation.
But, ignore the complexities of distortion etc, until you understand enough about it's operation to ask the right questions and then able to interpret the answers the sim gives to those questions.
