[sdiy] Buffering an op amp's output

[Glen]

Does anyone have a favorite circuit for buffering an op amp's output, to
drive low impedance loads such as a 4 ohm speaker? I thinking of perhaps
adding buffer transistors to the output of the op amp, and including the
transistor buffer in the op amp's feedback loop. Would that be the
recommended way to approach this?

My end goal is to build a high-quality, low noise, low wattage, audio power
amp using a pair of 5532 op amps, along with some buffer circuitry.


thanks,
Glen
