So you found a speaker with a metal dome teweeter that is not harsh. I'll bet you that there are far more speakers with metal domes that are considered "bright", "edgy" or "harsh" than are not.
BTW, the tweeter in the Harbeth is one of the few metal domes that is excellent. I believe it to be a Seas and it has been used succesively in some of the best speakers over the past twenty years. However if you look closely at it you will see that they use a clear "acoustic lens" on the back side of the grill to block the ringing that leads to a harsh high frequencies.
