Hi, I am looking for a schematic for a simple DIY headphone / line outputs setup. Can anyone recommend something?

I am looking for something like this that I could build myself in DIY format:

Thanks!

Thanks for the recommendation. I am also going with a non-inverting amplifier topology so I'm glad to see that is also used by someone else.

The circuit seems somewhat over-engineered in couple places however. Any idea why two op-amp are used for each output? Is this just to increase the current at the output?

Cap to ground on the output also seems a little weird. I guess that's just to provide a little lowpass filtration, but it seems like an odd choice though to go with a passive filter in one place when you have op-amps which could be used for that exact purpose.
