Remember your first live concert...


For over twenty years, Quadraspire have been enhancing the quality of customers’ hi-fi systems with their beautifully designed and manufactured hi-fi racks. The company was established by Dutch designer Eddie Spruit in an East London studio in 1995. The companies design, development and craftsmanship now all takes place at it’s manufacturing facility south of Bath. In the same way that the finest musical instruments are developed, Quadraspire use the same tried and trusted technique of tuning by ear.

Quadraspire X Reference
– an exceptional stage for your hi-fi

In the same way that every musical performance needs a stage so a hi-fi needs a stage to bring music to life in your home. Combining the technology of the SVT rack and the bronze upgrade, Quadraspire effectively created a rack within a rack making the entire system more musical end enjoyable.

The Xreference is a rack within a rack with each X shaped shelf supporting and SVT shelf with solid bronze feet. Finally small bronze spike locators hold the SVT shelf and bronze feet in place on the X shelf.

The X shelf is made from laminated bamboo coated in Nextel for damping without added mass. Each X shelf is supported by 44mm concave alluminium columns. The Xreference uses a larger diameter column and thread to lock the 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 Xreference rack are the solid bronze feet and spike locators. These two components have been specifically tuned to deliver the most natural performance on the Xreference. 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.

The X Ref shelf is coated in Nextel and the SVT shelves are available in Solid Bamboo or Natural Wood veneer finish. The natural wood veneered shelves are available in Cherry, Oak, Maple, Wenger and Black.
