This is a circuit I found at this sight for headphone amps:

I really like this circuit and I need some help from someone to modify it into a discrete op amp.
I was thinking of using it in an I/V and filter circuit of a DAC.
The input and driver parts I think will work perfect. The output stage is a high current one for driving headphones.
Using only one pair of bjts instead of 4 is a good idea?
Should the emitter resisotors be smaller like 4R7 or 10 Ohm ?
Could I just avoid the servo?
I don´t have so much space for it.
Also it has no overall negative feedback. Can you just apply it from output to negative input like an opamp ?
