Newbie Q re: opamp drop in substitute



I got this little headphone amp board from a Japanese hifi magazine. It uses an OPA2134PA opamp chip (plus another 2 for balanced operation). I think I've seen somewhere before that opamps in a headphone amp can be easily swapped with substitutes to have a different sound, but I have no idea what chips are proper drop-in substitutes. Any idea?

Thanks.
