I have two questions:
1 Do you already have a headphone amplifier?
2 Would you mind using e.g. a Chromecast Audio streamer instead of a computer? I ask because computers usually have usb output, but amplifiers with usb input tend to be less common/more expensive.
In a situation like yours you want the cheapest decent amplifier you can find (e.g. a Yamaha AS 501), to have as much budget as possible for the speakers. In a small room like yours I would avoid floorstanders.
Small active speakers would be a good alternative, but the choice is more limited.
