To extend the benefits of the Bronze upgrade to all the components in a system Quadraspire developed the X Reference. Combining the technology from the SVT rack and the bronze upgrade they effectively created a rack within a rack making the entire system more musical and enjoyable.
All Quadraspire racks are designed to be light and rigid to deliver a clearer, cleaner musical performance. Quadraspire achieve this by combining Wood or Bamboo shelving with solid Aluminium columns & feet.
Another key to the success of their racks is the shape of the shelves. Square or rectangular shelves encourage standing waves which can distort the sound of your system. By using a curved design they avoid parallel lines thereby reducing standing waves as well as reducing mass. Quadraspire extended this principal to the Xreference shelf employing extensive listening tests using the tried and tested technique of tuning by ear in the same way as the finest musical instruments are developed. The end result is the Xreference shelf with a cut out in the middle to also reduce mass as much as possible. The X shelf is made from Laminated Bamboo and is coated in Nextel for sound deadening, and the edges employ a more acute edge than normal to lower weight and assist energy dissipation. Finally small Bronze spike locators hold the shelf in place, shaped conically to give a natural sound.
The Xreference uses a larger diameter column and a larger thread to lock the X shelves together to be very rigid whilst still remaining reasonably light. SVT shaping on the columns and internally where the columns clamp the X frame further reduce parallel lines to reduce standing waves and improve sound. 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.
