I wonder if the OP is still with us. You know, it's now been some time since I did those auditions, but I think the first time I heard the F100/200, I was at Best Buy and compared either the F100 or F200 against the KEF R11, not the R11 Meta. I do remember thinking there was more clarity with the ML's, which would make some sense in that they measure brighter than the R11's. With my old man ears, maybe I just need more highs. I do also remember that I felt they offered such powerful highs and clarity, yet without any obvious distortion. The R11's in comparison just seemed a bit "lame" at the time. They also had a set of B&W and a set of Definitive Technology towers, neither of which I cared much for.
Now, I later heard the F100's at a Best Buy location and they had the R11 Meta's. I'm not sure why, but in that audition, I felt the KEF's just about equaled the F100's in clarity. I'm not sure if the R11 Meta's measure a bit brighter than the R11's, but it seemed that way to me. If I went KEF, I would definitely get the Meta's.
As to the bass, I don't think there was a big advantage with either brand, at least in those Best Buy audition rooms where they have a bunch of speakers lined up.
