Best Speakers Compatable with System

I'm in the procesw of upgrading my Artemis-Eos speakers, and am looking to spend about 8-10K new or used. My system consists of BAT VK 75SE amp, THOR pre-amp (tubed, and neutral sounding and dynamic), and a Cary CD301 cdp, which is also tubed with NOS Amperex. Cables are Magnum reference and Synergistic Designer Reference. Speaker cables are XLO, top of the line. Room dimensions are 13x25; sound treated. Listen primarily to Blues, Jazz and some rock music, especially female vocals. Would appreciate any suggestions with respect to speakers to consider that would be a good match for the rest of the system. Thanks for any feedback
