Old stuff, has been discussed before in this forum and also been changed in production. The bass filter was intentional and did not disturb anyone. The measurement results themself look like they have been done by a questionable software/process that has upset a lot of people and has never been fully explored or explained. The low cut in the Babyface input is totally overweighted in those results.

I wouldn't worry about it, there is a lot more questionable in that review. Like in most reviews...
