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
