Sometimes I miss note thickness of my Sony MH1C, its mids was not a match with B3 but it sounds fuller. B3 sounds like it is tuned up to a half octave thinner note than RE400 or MH1C just for instance.
I listen both consecutively, and think that either Joker should have a very special RE-400 or I hear it differently. After listening them both, I put my beloved RE-400 in it's box to prevent collecting dust. Mid 8's is an insult for B3, if RE-400 is not Low 8's or High 7's
