The general theory here is that there's no way to recover extra data from an input in the digital stages so you want to apply as much gain as possible in the analouge domain there. On output the reverse applies so you want to do any attenuation in the analogue domain so you get the maximum resolution from the DACs and attenuate their noise floor.
