Speakers for a unique small room

So I have been going about speakers all wrong.  I am used to having a large listening room, but due to a divorce i am in a house that is pretty small.  I will be buying a new house in July but I need some good speakers for a small room now and hope maybe they will blow me away for when I get a dedicated room. 

So first here are some specifics the size of the area where I listen.  The room is 10 feet (3.1 meters) x 14 feet (4.3 meters) and the listening position from a speakers which front is 3 feet (1 meter) off the wall is 8 feet (2.4 meters).  The 14 foot wall has a large window, behind the listening area are stairs going up to the 2nd floor and their is no right wall as it is open to other parts of the house.  Here are some pics to put things into perspective:

So right now I am running a NAD M12 and M23 as well as an SVS 3000 Micro, My speakers are PSB Imagine X2T an 8 feet is just WAY to close.  I want something that if I am sitting 8 feet away from sound amazing!  I cant listen anything fatiguing, I am looking for a bookshelf.  I also would like something that would be amazing when I have a dedicated room as well.  I have tried the LS50 Meta, still have them but thought they were mediocre at best.  

So I am hoping I can get two pieces of advice, great speakers for a small listening space.  Harbeth P3ESR XD's are the only speakers I have seen that can be great in small spaces.    I want something that will be great and I have a budget of $2500 with a little wiggle room.  Would love as wide of a sound stage as i can in a small room, No Klipsch and no Focal please.  Great speakers but just way too fatiguing to me.  

I listen to a lot of Jazz and Classical the rest is filled with Grunge, Punk, and Classic rock but Jazz and Classical are my priority.  

Based on the pictures if anyone sees any opportunities for treatments in any way please call them out and I will get them.
