I have no bias against soft domes, I like both, but don't count out metal domes when done right. I believe a well designed metal dome does not necessarily have that sharp or ringing signature. I would think it has a lot to do with crossover design also. On the other hand, -sometimes- soft domes can tend to sound soft on leading edges, and don't do the sound of metal percussion well.
In my experience some Totem and Alon speakers using metal have stood out as having vivid high end response without harshness.
