Vantoo Transparent Zero (good) or Vantoo Transparent One Encore (better) are great choices if you need a compact system that has volume control. They are active speaker systems. They include multiple inputs (USB, Toslink Optical, Coax, analog and Bluetooth wireless) and a remote.
I do not own these speakers, but I've read the reviews and there are some trustworthy owners here on this forum. Hopefully they will reply, or you can do a search on "Vantoo".
This is what I would buy if I were in the position you described.
