It's a HiFi amplifier for my AKG 272HD.It can use for other earphones or speakers,too,you only need to change the feedback resisters.2N3055 and 5532 can make it.

The regulating loop is only for AC and does not take care about DC. This is because of the caps at opamp output. This will cause a DC drift of the opamp output endup with clipping. Test it by changing the AC input to 1% phase offset and restart simulation. Measure the opamp output and see how close it comes to 15V or even clipping. Keep it up!
