You might want to re-read what I said, which was- IF you wanted to tweak the levels. I don't. Most folks only make small level adjustments to the center and/or sub. By the way, a phantom center is great as long as there is only one (or two of you close together) occupying the "sweet spot". Having a center speaker works much better as it will anchor the dialogue and central sound effects way better for people sitting "off-center". I do like a "phantom center" when I'm listening to two-channel music.
