Magnepan, Ohm, Spatial or ??

I had a set of Maggie 1.6qrs that I really enjoyed, but they do take up a lot of room and have to be out from the walls. This really complicates their use in a smaller or multi-purpose room. When I moved a number of years ago, I had to sell those. After trying several other speakers, I settled on a set of Ohm 1000s that I really, really enjoy. The current room is roughly 13' X 15' with some odd openings. The Ohms work perfectly for me.

@soundchasr  The three speaker examples you listed have very different presentations of sound. I'm a big fan of omnidirectional speakers and horns (which you did not mention).

Besides the Ohms, which are great speakers, I would recommend Shahinian Obelisks (my personal choice) and Larsen. Obs are in your price range used and the factory support is great.

In the horn camp, there are Klipsch Heritage (Heresys would work great in your room) and other vendors. I just purchased a pair of JBL L200T3s for one of my daughters. Baby butt cheeks! They sound great and work in her room which is similar to yours. Powered by a tube amp - she's happy.

Ohms would work and you wouldn't need to wonder which side of the room your black absorption device decided to lay. 

I have both MMG's and MicroWalsh Talls and they sound nothing alike. I enjoy both presentations but they are different beasts altogether. Never had the pleasure of hearing Spatial.

I've been looking at a similar group of speakers: Magnepan, Ohm, Spatial, and Eminent Technology.

Amongst several unknowns and challenges is the "direct sales model", used by all but Magnepan, which makes auditions difficult here in Dallas. 

I just made my choice of speakers based upon available room placement. 

Three of the contenders require 3 feet of rear clearance from the wall: Magnepan 1.7i, Eminent Technology LPT 8b, and Spatial M3. That is doable only on the short wall of my 14' x 24' living room.

HOWEVER, that position creates a cascade of issues: furniture placement, re-installing a tiled-in HDTV, removal of a beautiful bookcase to gain space, and odd room orientation once accomplished.

Choosing the long-wall position and a narrow Ohm speaker, which must be used close to the wall, has multiple benefits.

Positioning the Ohms on the long wall flanking my fireplace allows the use of the stereo gear in support of HDTV videos. The HDTV itself will not have to be removed from its tiled-in nest in the fireplace, and the resulting room will focus on the fireplace and HDTV as I think it should.
It might seem strange that I've given so much consideration to things other than speakers' sound. As I cannot easily audition 3 of the 4 contenders, and that a good used pair of Ohms has come available, makes it very reasonable to me.
