I will use driverstage too... and will have chance to bias output stage to class A...
whats your supply voltage-?

Supply is +-25V.
I think the darlington model in the simulation is wrong because it is missing the inner resistors in the transistor. I changed the circuit a little bit and biased for 150mA. Still have about 620mV at the base. I don't understand the 2V and -1.8V in the simulation.
