Help please

I am really starting to think my room is possessed

Sorry gents was fairly upset when i wrote that.
So heres the scoop,
Eight years ago I accidentally turned up the volume and blew the drivers in my dynaudio C-4 speakers. Sent them off for repair and when they returned I noticed one side (left side ) was clearer , right side not so good. So I thought the speakers had to be broken still, eight years later and new speakers new cables, new amps and left side still plays great and right side like crap. Have move the system five different places in room ,same thing. Even built a wall in my living room to even bass. Thousands of dollars worth of GIK acoustics. Now my new speaker on the right side sounds like a midrange diver is blown and I’m pissed off. My system used to play wonderful until that day eight years ago. I have tried a lot of other things , just to much to list.

Dynaudio did the repairs. I have had three other pairs of speakers in the room. Same thing. All my electronics are Simaudio and had them tested at sim and was told everything was good. My cables at the time was MIT oracle and i had a problem with one of the interconnects before this happened so i even bought new cables.
I have even had my AC tested. Over the eight years i have  got the system to play great for a week or two then rifgt back to the same old crap.

My speakers turned out not to be the problem. I still think it was in my electronics somewhere. But now one of my new speakers sounds like a blown driver. My dealer moved out of state, but told me just to start over. I laughed

I need a fresh set of ears, that's one reason i started this post .

I can put the speakers a foot apart from each other and hear it plane as day. Now I know my room is far from perfect but this is very noticeable. I have switched cables and it will follow somewhat, but i have two of everything and its always exactly the same. I wish i was kidding.

I will try to explain a little more detail,
My system eight years ago consisted of all MIT oracle ma speaker and interconnects, Dynaudio C-4 speakers , Simaudio supernova cd,Simaudio P-8 preamp , Simaudio W-10 mono blocks pluged into a dedicated outlet, everything else into a shunyata hydra. I was on the couch listening to music when wife walked in and I accidentally hit the up volume . By the time i realized what i had done ,pop pop pop pop, well i think you get it.
The system has never played right from that day. Speakers were repaired by dynaudio, bought new ones just to make sure it was not the speakers (Eggleston works andra 3 se ) and just bought new amps trying to cross off the amps as the problem.
So my system now is Transparent mm mm2 cables and cheap audioquest cables , Eggleston works speakers , Theta Prometheus mono blocks , Simaudio P-8 and P-5 preamp , Simaudio andromeda cd player into a PS audio P-5. The new amps have been in only about a month and my speakers about a year and they sound like they are having problems. Left speaker good deep bass and very clear sounding , Right speaker sounds softer, bass is gone and it sounds like its laboring to play music in the midrange area. If i switch the speakers in the room the speaker that was on the left now dominates on the right side. I believe i have somehow damaged the midrange driver in the other speaker now. Very upsetting.
I am not sure what is good in the system anymore, thats why i am trying to hire someone to help at this point in time.

Maybe a bad time to mention this but I will be doing a review of my new amps (Theta Prometheus mono blocks) they seem to be quite good.

Update 
I have been emailing Jim Thompson all day , owner of Eggleston works speakers. What a great gentleman. So i put my Dynaudio C-4 speakers back in and everything is good again, so i told Jim what im hearing different and we are going through it step by step as i have something wrong with the Eggleston speakers. I still dont know what started all this mess, but with the new amps and my back up pre amp in there its working for now. Thanks to everyone for your suggestions.
