Jjue,
Our cases are similar, difference is the electronics.
the MB2.5 crossed 120hrs, and the bass considerably improved, which helped other frequencies to emerge and it is listenable now, out of box the sound was nightmare.
I was even planning to return the speakers to dealer and get whatever refund the store can offer, however the good people in the forums helped me to stick to the speaker and will wait till the burn-in is complete(500hrs), however the from this point we can expect only good sound to come.
