    I imagine the words mean what you want them to mean.

    My interpretation is that a buffer isolates the source from the load, possibly by having a high input impedance and a low output impedance.

    A preamp amplifies the signal, it may or may not have controls.

    A buffer typically has no voltage gain. An amplifier typically, does.
