While the black looks really good, I'm not sure it's going to match my F700BT, as it's "off" black. Think I might have to get a stainless now. Hah!
don't worry about that. if you look closely you can tell the black knobs in the original post are just the silver knobs flipped horizontally and then digitally altered so that the color looks black. I would wait until you see actual pics of the black knobs before you decide against them due to color matching issues.
