a single transistor stage with, say an emitter follower would suffice
though these days the over designers would probably use an Ic.

**And just to nit-pick: With a single transistor, operating as emitter
follower, you have a Voltage gain of less than 1. Just sayin'. I think
you mean 'common emitter'.

An OP amp is very, very easy, cheap and simple to implement. Distortion
is almost non-existent too.
