I've recently built a few headphone amps that fit in Altoid tins.
It's barely about boosting the output level (though it will do that)
and more about making the source device's output work less hard and 
possibly distort.

The URL below goes to a page that compares many different op-amp chips
and discusses (among other things) the wau they affect the sound.  I
ended up using the TI OPA2132P (a dual version of the Burr-Brown OPA132)
and I quite like the way it sounds.
