NHT M-OO powered monitors with a Bellari VP-129 phono preamp. It has a volume control and a headphone jack. A passive pre-amp can be added for little money if you want multiple inputs and a sub if you need more bass. All this can be done incrementally. Your space is too small to warrant concern about most of the audiophile issues you see addressed here.
I wouldn't spend a lot of money unless you will be using headphones, in which case the room is not an issue. Not only is your room small, it is a cube. That's the worst acoustic obstacle you can face so headphone or very nearfield are your best bets.
