I have a slightly smaller sized room, about 10m x 4m with a Naim Super Uniti and CDX2, my speakers are Neat Elite SXs which I find to be excellent, since I ungraded from a Uniti. They are placed relatively close (30cm) to the wall/window. The base is controlled and the soundstage perfect.
I compared these with some Momentum 4 which gave overpowering bass, for my taste at least.
Very happy with the set-up and I would suggest you give it a try in your room.
