Center image on left side and don't know why

I have this problem too and concluded that in my case it is a room/speaker placement problem. My "center image" is usually 3-5 dB to the left of center (but it varies with music). I can center it by moving my listening position, but don't like this solution in my room, so I only use pre-amps with balance control.

Some good pre-amps with balance control are Sonic Frontiers Line series, ARC LS-25, and Levinson SS pre-amps. I use the SF Line 2SE, and there are several good but inexpensive pre-amps with balance control, ie Adcom. Cheers. Craig

The problem occurs with all of my speakers(BG Radia, Green Mountian, EFE Tech, Michaura) amps(Jolida, ASL, Vecteur, Sansui) and sources(CD, digital music, tuner). It's got me baffled. I do notice that when I move my head laterally to the left about six inchs the image stabilizes in the center. When I look at the left soundstage the image moves even further to the left than when I look straight ahead. It occures on both the long and short wall. My room is 15x30x8 and symetrical. I'm begining to think it is my hearing. Even thought the doctor said my ears are clear I bought some Murine ear cleaner anyway.

Do others listening to your set-up experience the same phenomenon? If no, then it sounds (pun intended) like a hearing problem (right ear).

Just experiment with moving 1 single speaker foward or back to get it to lock in, that will likely fix the symptoms and may even be the cause....

Socrates you are on the mark. I moved the right speaker about 9 inches forward and the center image locked in. It must be the ear. Maybe the ear drops with perform magic but it looks like I'm stuck with a bad ear at 38.(<:

Now is when I wish I had an amp with a balance control. It kinda bothers me that one speaker is ahead of the other, you know.(<:

Thanks to all for your advise.
