Blue Grey sounded too weird for me, almost like FM Radio
Ymmv perhaps. With my setup, also using spinfits, listening to Radiohead for example ("how to disappear..." from Kid A or tracks from A mom shaped pool) I overall get nice presentation. I did give a little disclaimer when I found that grey+blue was mid centric with the bass being subdued, more than usual. Give it a shot with different recordings -- I'm just glad that the blue bass filters have their place because they contribute to the overall experience.
