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

Get "Get Better Sound" by Jim Smith. You may have micro-misalignment you can fix with that book.

Download free RTA application for iPhone, run pink noise from speakers, and see what you get at listening position. Then repeat with each channel individually. This is very crude, but also very helpful. Something in your playback change probably has "balance". You can adjust this if you cannot rearrange your room to be more symmetric in response.
