Driving me crazy


Wow where do I begin.
About seven years ago I drove the volume up on my amps to high on accident and popped the bass drivers on my dynaudio c-4 speakers. Sent them in to dyn and had them fixed. Seven years later and two different systems, acoustic treatments, new speakers, cables, cd player, moved the system four different places in the room and the left side always has more bass and sounds crystal clear. Now here is the cool part, if I switch the speaker cables on one end of the amp or pre out at the preamp the right side gets better.
Sometimes I move things around and it plays good for a day or two then goes right back to it. When I am sitting in front of the speakers and change the balance on the pre-amp I can clearly hear the difference.
The only thing I have left is something in the AC power, and I did have it checked.
I could go on and on about all the things I have tried in seven years, but it would take me a month to explain it all and I figured no one would believe this story anyway. Next up is a priest.
I can tell you a little is my room and I know that, my hearing is fine but I am ready to get a baseball bat and put an end to my misery. If anyone has a good suggestion I'm all ears.

I have cleaned them many many times thinking the same thing, but not the problem.

I have been doing this off and on for seven years. I built a wall in my living room, I gone so crazy with this.

I moved the system to the other side of the room, where my sofa is in the pictures is where my system has always been.
I do have a guy in Sarasota maybe comming to help me.
By the way i have bought all kinds of acoutic treatments from GIK and even a Dspeaker 2.0 dual core, no help. treatments make it sound worse.
And please dont laugh, but bought new speakers thinking my dyns were still broke. But the little cheap speakers do the same thing, so i jumped the gun again
To eliminate its not the room caused the problem, can you connect a headphone to your power amp speaker output by using a headphone adapter to confirm it?  
I have a retired audio expert coming by tomorrow afternoon to help.
I will keep you posted.
