Great Small Room Speakers for $3-5k

Hi all, I'm looking to upgrade from my current speakers (Zu Audio Omen) in my small room (13x10x7: WxLxH) and willing to spend $3-5k. I'm looking for a slightly more transparent speaker than the Zu's and also a smaller speaker. I'm open to new and used speakers. So, I've turned my attention to bookshelf speakers and small footprint floorstanders. I have a Rel subwoofer to buttress low end. Most of my listening these days focuses on blues, soul and R&B, classic rock, and alternative hip-hop. 

My system is: Rogue Audio Sphinx v3, Bluesound Node 2i, Rega P3 TT, Rel T7/X sub.

My nearest Hifi shop focuses on Harbeth, Spendor, and KEF. So far, I've liked the Harbeth P3ESR and Compact 7s and the Spendor A4. But, I'm curious to get other suggestions. I've been interested in the Devore Fidelity O'Baby but are just above my price range and can't be demoed right now.

Does anyone have experience with those aforementioned speakers in a small room? What else should I consider for a smallish room in this price range?
