Seeking and making recommendations on speakers out of context (system discussion) is not productive.
I guess he has not heard a good metal dome tweeter, then, or at least set up in a beautiful system. I am reviewing now a dynamic speaker with a metal tweeter that has some of the most scrumptious high end I have heard in my room. The tweeter performs on a level with the ribbons I have used. Not the same dispersion, but every bit as erudite and flawless sounding. BTW, that is not a tacit endorsement of the speaker discussed in the OP. Everyone has their preferences.
Review will be out in time.
