cost don't matter much. application is mic pres.

Personally I've never found the couple of hundred microvolts output noise (
audio band ) to be a problem. If you're getting more than that, your problem
is something else.

If to make it really quiet, considered an emitter follower output buffer
after the 317/337 with an R to the base and C to ground ? Really cheap
although you'll lose about a volt.
