Yes, many of us do that exact same thing. I usually bump my CC up by 1.5 to 2 dB's over the mains. I'm not sure if it is related to my 60's being 8ohm and the VP150 being 6ohms? If I don't people are always saying, what did that actor/actress say? And if you turn up the main volume to hear the center, then the other speakers are to loud. At least that is my situation.
