This TV I am really considering. On a previous thread however, one user stated he was using a magneticlly shielded center speaker and when he placed it on top of the TV, the picture would distort. This is keeping me away from purchasing the TV til I hear more feedback about this problem. Has this happened to anyone else who has placed a center channel speaker on top of the 34HFX84? For reference, the center channel I am using is a Definitive Tech C1.
