@backdoor , It is, but I have no idea what you will accept as reasonable performance. You might be perfectly happy with a system I would deem sub par. But you have spent a lot of money already so my guess is it is important to you. If it is imaging you want the first thing you have to provide your system is a symmetrical environment. Stereo is all about symmetry. If one channel differs from the other in any way the image is chipped away at depending on the severity of the infractions and in the situation I see in your picture they are legion.
In a residential situation with the size rooms we normally have you want a flat front wall and two clean corners That extend for at least 6 feet in front of the speakers This should be on the short wall of the room. Both speakers see a corner and the listening position will be somewhere in the middle of the room away from the back wall. If you use the long wall the listening position will be up against the opposite long wall which will really create amplitude problems. With the type of speakers you have you will need sound absorption on the front wall, side walls and ceiling. The speakers need to see an exact mirror image environment. From there if you want SOTA performance it takes a little digital signal processing which scares the h-ll out of the analog crowd. Suites me. It keeps the price of digital processors down.
I only mean to help and do not want to see you wasting money chasing a faulty situation that might be able to improve a little but still will never approach the performance it should, the performance you expect.
