I fully agree with you but I see where this is going... Well, there are many non-diamond speakers out there as expensive (or more expensive) than their diamond competitors. Manufacturers are always looking for improvements and pushing each other. Call
it hype if you will, but my ears never heard as good speakers as we have nowadays (diamond or not) and the best ones are unfortunately big, heavy and quite expensive, regardless of the material used for their drivers. Such is life...
