I was impressed by the Zylon material used on the Yamaha NS5000 tweeter. However, my impression could be a product of the complete speaker package because the mid-range and the 12 inch woofer are also made from Zylon.
I am also a big fan of the driver in the RAAL SR1a "earspeakers". I do not consider them headphones because they do not sound like headphones but 2 channel speakers. The detail out of that driver is incredible.
