If speakers disappearing is your desire, my experience is that Audio Physic can’t be beat. I’m using Scorpios in a similarly small room with vacuum tube electronics. Huge spacious soundstage - disappearing walls. My room has lots of variable bookshelf, record racks, desk and such to break up any constant reflections - so that contributes to the effect.
Have also used A P Virgo with similar result. Should be available on A-gon for your price range.
