The X shelf is made from Laminated Bamboo coated in Nextel for damping without adding mass. Each X shelf is supporting by 44mm concave Aluminium columns. The X reference uses a larger diameter column and thread to lock the X shelves together for increased rigidity. The curved shape of the column further improves performance by avoiding parallel lines and reducing standing waves and mass.

At the heart of the X reference rack are the solid Bronze feet and spike locators. These two components have been specifically tuned to deliver the most natural performance on the X reference. This results in a rack that makes equipment perform to a surprising level, offering a very low noise floor for greater definition of music and opening up the soundstage in all dimensions.
