Oops, haven't replied to your question of last week yet. I've come to love ceramic drivers ..., if they are expertly done (Avalan, Ayon, Tidal, Thiel). Though I can't say I've heard so many as to justify a statement of general superiority, so I won't. The thing is, they seem to perform exquisitely in an area that's high on my list of virtues: they are fast. Immediate attack, very natural decay. Is it they don't store energy that much as e.g. metal that upon release can muddle up the signal? The other thing is, they appear very uncoloured to my ear. For instance, I very much like Antonio Forcione recordings; the Tidals make for a beautifully melodious acoustic guitar where the instrument is played like that. On the other hand, Forcione will suddenly accelerate, hard slaps on the strings and the wood and... no speaker to spoil the fun! If it's inexpertly built though, you can get an edginess that is hardly enjoyable. Also, combining ceramic drivers with other material must be a very delicate art mastered by not so many. But again, I'm not fixated on ceramic drivers. (Well, I like to work with ceramic kitchen knives also, but apply them wrongly and you can bid farewell to your knife, so I use Aritsugu knives just as often ;^))
