I feel like that would be a shame. If Dr. Fang is so smart, why doesn't he just use the right shape/materials for cups, use the right amount of wool or other damping stuff in the right places, etc? If this is a "statement" "flagship" headphone, why ship it in a state such that an hour of amateur modding can immensely improve it?
There must be something about headphone production that I do not quite grasp.
Analogy: If I buy a Miata, I might expect to want to mod it to make it better as a racing machine. But if I buy the top of the line Ferrari, I would expect it to already be as good as it could be.
