So it sounds like you’re dealing with a room issue more than anything.  If that’s the case and you otherwise like your speakers then playing with placement would be the first thing to do, and there’s no guarantee switching speakers will leave you any better off if it is a room issue.  My guess is pulling the speakers further into the room could help a lot given you noticed an improvement pulling them 4’ into the room, and generally speaking getting the speakers 25% into the room away from the side walls is also beneficial to decreasing room modes.  If you can’t mitigate this with placement then bass traps may be the next thing to explore if you haven’t already.  At least playing with placement is free, so there’s that.  Hope this helps, and best of luck.

I completely agree. I would not give up. My fist thought was bass traps… and if you already have them then maybe one between the speakers against the front wall, and definitely keep working on positioning. 

I have Sabrinas and they produce enough bass to overwhelm a small room. The way I mitigated it was by placing GIK Limited Range tri traps in the corners behind the speakers in addition I have 204 bass traps. I also changed interconnects to Nordost Tyr 2 that are better balanced top to bottom without emphasis on any particular frequencies. Bass is right on at this point. 
Take a look at my system pictures.
