Interesting, I wouldn't have expected that. Maybe the dampening effects that the J$'s have on dynamics cannot be compared to that of orthos...? They definitely make my dynamic cans sound way bassier. Maybe, as you and davidsh mentioned, they have a more brightening effect with orthos. Not sure my curiosity is high enough to peel off modulor's pads
muhahaha, you really should give in to the curiosity, just so that you can "hear it" at least once.
