The amp signal side shouldn't ever have 400+ components! Only if your over into home theatre stuff and want all kinds of gimmicky effects stuff and then that's done with IC's like your wanting. That's not high quality audio territory, more like tons of buttons to impress the unknowing, unhearing masses.
It sounds like your referring to (1.4v) the supply rail and chips. The signal in will often be more than 1.4v and you don't want to drop it down and re-amp it. Not the direction you go with audio.
Just so you know, the typical amp structure is more like a voltage gain stage and then the output current driving stage. Each of those stages should be a handful of components, not hundreds. Also, you throw in one of the variety of specific to the design input circuits which could be another handful of parts. Neither of the two key stages is typically run on low voltage.
About half the amp should be the power supply. That's where quality originates. Little there is done in the IC world and less yet at the low voltages.
Big packages of chips are for solving munchies, not high quality audio.
