Symmetrex tonearm on WTA?

What is this? Can't find information. All the website says is that the Amadeus 2 includes the new Symmetrex tonearm.... not sure what that all means. It looks like they've replaced the golfball with some other thing.

Has anyone heard the new WTA with it?
It's still a golf ball but it's cut in 1/2 and attached to a little metal cover. Makes it look less like a science project, but it's really the same concept. I have the Amadeus Mk2 and love it. I haven't heard the original version in order to be able to compare the old tonearm to the symmetrex, but I'm really enjoying my table. Could be the best Christmas present ever.
