Room acoustics how ? My image is not centered


The sound of my system is not good. the image is tending a bit to the left and not centered, the sound is "hard" and there is no much stage.

I own Merlin MMe, VAC Avatar super, Electrocompaniet EMC1 CPD, cables: audience au24, cardas golden reference

as for the unbalanced, I tried all the combination's of switching cables sides and every time the sounds is bit stronger on the left. so I suspect my problem is with the room acoustics. the left wall is made of concrete bricks and the right wall is all glass-fronted (maybe this is the cause?) the ceiling is made of wood.
do you know how can I scientifically measure and check the sound in my room ? and scientifically found the places where I need to put some materials for better acoustics ?
any good info and/or reference for web site explaining on room acoustics ?

about my amplification (VAC AVATAR SUPER), I suspect (only syspect) its really not match the Merlins since the sound is bright and "hard". anyone have experience with it with the Merlins ? better suggestions for amp or pre& for the merlins ? (for used price ~5500$)

thanks

I assume that you have done all the measurements perfectly. One method is Jim Smith with Get Better Sound. It is not mathmatical but is acoustical. Money well spent. Once perfectly positioned then room treatments will help balance the frequencies. I have a problem with channel tracking at very low volumes with my preamp which will favor the left at very low settings. I am getting new matched tubes. Just a thought. Good luck.
Based on this post and my difficulties with my room I had tried everything I could think of, until I tried the Sumiko Master Set method. Its the only one that worked. Everything snapped into focus. The images float in the air. I can't hear one speaker over the other no matter where I sit. The midrange is natural and lifelike. The bass is even and full without exaggeration. It took about 2 hours but finally I can rest easy. No bull. It works. I have an odd room with a ceiling that is lower on one side and asymmetrical furniture. It doesn't matter. You are tuning the speakers to the room. No formulas. Similar to Jim Smith but infinitely easier.
There are several post on Audiocircle. I'm not home now. Try "Sumiko master set speaker placement" and look for the audiocircle posts. Email me if you don't locate it and I'll send you a link. Good luck!
