Speaker Placement Issue/Thoughts

I'm not sure if it's my hearing, my rooms (I've had the stereo in three different ones over the past few years), or a recording bias, but I consistently hear my image being biased slightly left of center.

I've had to resort to balance controls to fix this issue, but have also tried various speaker placement solutions (Thiel 1.6s and now 2.4s). When thinking about how to address the problem, I regularly get stuck in what feels like a logical paradox.

So, to shift the center image to the right, I can alternatively convince myself either that I should A) make the right speaker louder by moving it closer to me, or B) move the right speaker further away to shift the actual center of stereo speakers. Unfortunately every time I try to test this, so much ends up changing (the damn spikes are so hard to deal with) that I never figure out which is the appropriate solution.

Maybe I just need to pay a professional to come in and place everything for me...
