Kharma, Wilson Sophia, JM Labs I'm confussed????

I currently have the JM lab Micros (non BE). I'm driving them with a YBA passion integrated at 100w/ch. My room size is about 16x14x12. I'm thinking about upgrading to a full size speaker vs the monitors. I'm currently running my system with a REL Storm sub. It does fill in the bottom well, but it doesn't have the full range sound. I want to spend under 10k. my thought was used wilson's, or JM lab mezzos, or one of the Kharmas. i'd be anxious to hear some advice?
