See my circuit "current", there is a difference between them, can u find it?^^

Going out symetrical from first stage to second will short circuit the VAS diodes (voltage adapation stage) of second stage! Anyway, second stage is in Class B mode, there is almost no Iq for class A. I would recommand to increase the current a lot for VAS diodes second stage (e.g. <1kOhm both resistors) to drive a low impedance in Class AB mode. Keep it up
