I got rid of my KEF Reference 5’s because I thought they were bright and quite analytical and replaced them with Sonus Farber Amati G5’s. While the price is above your price range, I would still say to check out the Sonus Farber Olympica Nova ll (new $11k, used $5-9k) If you can find used the Olympia Nova lll used. Or maybe the Sonetto Vlll ($8k new)
All the best.
