Wilson Sasha 2 or Alexia for small room 10' x 17'?

Thankfully the room and system does not suffer from the boominess or imbalance possible in a small room . The  bass is tight, involving,  and quite pleasing without fatigue experienced over long sessions. 
Vitop, I have not heard the Personas but am curious about how they sound.
The very talented horn player Sebatian Studnitsky's KY Organic on  a pair of Sasha 2's is heaven. He is a recent joyful discovery and would recommend his music!

996cupracer, gratulations with your speakers i really enjoyed reading this thread
( the parts that is about wilson )
I have been auditioning Focal Sopra 2 and 3, and then went to hear what Wilson is all about , i listened to Sabrina with ARC ref6 and ref 150 as well as Sasha 2 on same equipment, heard the Yvette on Devialet, and all i can say is that i was blown away, over the soundstage 3D, bass precise, height incredible.... it was so good and i could have listened forever.
I will for my part "only" be able to opt for the Sabrina sometime in the future....the interesting thing is that your room size is almost the same as mine, so i can only say if i had the money i would go for the Sasha 2 after reading your quest.
How close to the wall are they , i think back of speaker to wall ?
Lots of happy listening, i am sure.

996cupracer, I don’t have anything that I would call a practiced ear so I am not sure I can really describe it very well. I just know what I like.
Against the Wilsons, the Personas (in my opinion) are more detailed. Everything seems clearer and more detailed. And that is strange to say when comparing to a Wilson because I love Wilsons. So you would think that the Personas are a better speaker with my having said that, but I’m not sure that is true. They are different. I love the Wilson sound and could listen to them forever. The Personas can sometimes come off as a little bright but they are tremendous speakers.
Like I said, sometimes the dialog in a movie can be muffled or there can be a lot going on along with the dialog. The Persona will resolve all of that better than anything I have heard and you just kind of hear all of it at once with absolute clarity. Pretty amazing really.
Right now, I am really thinking about a set of used Wilsons for music (I still like the Wilsons for music better than the Persona), and the Persona for home theater. So far, those are my favorites for those two functions.
I am going to hear some Legacy Audio Speakers also, but am not able to hear them head to head against either the Persona or the Wilsons, so going to be hard to say if they will be better or not, but they are a speaker I want to listen to. Has anyone does a really good comparison between the three?

Similar to tires, it is very difficult even at the very high end to find one product for all applications. Some music just sounds better on certain speakers. We also hear differently and variably appreciate nuances in sounds. Hence the success of the multitude of manufacturers. 
I thought the Sashas were very detailed but your comments piqued my interest in hearing the Personas (not to buy but to experience). Besides the sound and build quality,  I like the fact my Wilsons and electronics are made in the US.
