The three front speakers ideally should all be the same distance from the listening position. If that is not practical, the delay settings in the 950 can compensate. The problem with the dialog being too low in level is something I run into all the time. This should not be the case, and I have my system calibrated to an insane degree, but it is a problem. I just leave my center at +3 in the trim menu above the reference level arrived at with the RadioShack meter.
