In-Wall Audio for One Room?

["joelfinkle" <joelfinkle@xxxxxxxxxxx>]

1) I'm adding one room, the rest of the house would be tough to do
multi-room audio.
2) I've got 50+GB of (legal) audio on my home net
3) The new room is a kitchen, so small components like a Roku or Slim
Devices network
media streamer sounds ideal
4) I plan to put in wall or ceiling speakers

So can I use an in-wall amplified volume control and single input
without a multi-room controller?  Or am I hopelessly naive.  It looks
like I'd need to get power to it at the very least, but that's not
insurmountable.
