I recently accuired an old Elektor Magazine from 1983. In it is a design of a 160mW Class-A discrete headphone amplifier.
I want to build it, but is it worthwhile to build a discrete amplifier (with way more components) or can I use a LM833, which I’ve bought already, and get the same quality sound?
I have no problem building either, but will have to design a PCB if using the LM833.
If the op-amp variation is better, is there a good PCB layout around?

1st question is what impedance are your headphones
high Z headphones like the senn hd series (300 Ohms) can be sucessfully driven by many op amps
low Z headphones like grado (32 Ohms) require more current than many op amps can supply
