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

couple thoughts. I have a somewhat similar goofy room and found after much experimentation that I was able to "position" my soundstage by having different levels of toe-in. I tried for symmetry but always was skewed. GOt my distances right and played with toe in on one side and than the other. Found I could get what I wanted with roughly 3 or 4 degree difference. YMMV. On another note I would be really surprised if edge diffraction is at play here when so may reflections can have a field day. If I recall correctly the equations indicated to me that sound diffraction in something like this should be about nothing. Have to think but off hand I doubt it.
great news T,

where did you find the details on how to do this method? I googled and Binged with no result. My room blows as well but I think I have it sounding pretty good but..........
