So Logitech with whatever experience it has in headphones used Graphene and was able to make this G Pro X2 Lightspeed headphone sound quite good (objective review is in RTings). I wonder what would a company like Austrian Audio would be able to do with it. AFAIK Graphene is not as expensive (G Pro X2 Lightspeed costs ~350 CAD with a 50mm driver) as Beryllium used in the Utopias but its material properties are on par, if not better than Be (which takes a role in making the drivers non sibilant). Now the Composer is not super expensive, and not sibilant, and the driver has high excursion .... I am just trying to add 2 and 2 lol.
