Ok, but does your audio gear have rotons (metamaterials)?

Not yet. But get ready for the LS50 Meta Meta.

"A group of researchers is working on metamaterials that "grow" rotons. Metamaterials exhibit optical, acoustic, electrical, or magnetic properties that are not found in nature.…Thus, it might be possible in the future to better manipulate sound waves in air or in materials, for example, to bounce them back, redirect them, or create echoes. These materials have not been demonstrated experimentally yet; however, it should be possible to produce them by using technologies such as ultra-precise 3D laser printing." https://www.sciencedaily.com/releases/2021/06/210610135559.htm
