I will put in a strong plug for the Audio Physic Avanti III's. I have owned the Kharma's but prefer the AP's. They do very well in a nearfield set-up and will give you everything back you give them. I mistakenly thought I had their performance maxed out several times only to find there was more there as I upgraded/changed a component, wire, tweak or positioning.
The Piega P10ltd or P8ltd would also be at the top of my list given your room and based on price for performance.
