Quadraspire Buyer’s Guide

 

X-Reference

The culmination of years of development at Quadraspire, the new X-Reference heavily features phosphor bronze to tune the acoustic response of the system. SVT bamboo shelves are fitted onto Nextel- coated bamboo X frames and isolated by bronze spike assemblies, the X-frames being supported by massive 44mm solid aluminum columns. This “double isolated” design brings heightened levels of detail, a supremely open sound across the registers, taught and extended bass, and perfect timing. Further tuning via optional aids, allows the rack to be optimised for your system.This truly is the best Quadraspire has achieved to date, designed for world-class HiFi systems.

starting at $1799 per level

Sunoko Vent T (SVT)

Suitable for mid to upper priced HiFi systems, SVT represents a sizable improvement over the entry level Q4. Shelf thickness and depth are increased, allowing for more sizable components. Core to the Quadraspire philosophy of sound, mass is kept in check via slots cut through the shelf, which has added benefit of increased ventilation.The shelves are support by concave 32mm solid aluminum columns, tuned to reduce resonance optimism quick energy transfer from level to level. The resonance of the shelf is tuned further via brass inserts where the columns make contact. Available in veneered MDF, or solid bamboo to further improve sound.

starting at $449 per level

Q4 Evo

Designed expressly to prove that furniture makes a different, Q4 makes improvement to the sound of any HiFi system that is easily appreciated.The curved and chamfered edges of the shelves reduce standing waves and resonances.The undersides are carved with an intricate pattern that further reduces mass and breaks up any remaining vibration. Shelves are supported by straight-sided 19mm solid aluminum columns. In fact all, ferrous metals are eliminated which has a very positive impact on sound. Leveling spikes are included, isolating the rack from the floor.Available in veneered MDF, or solid bamboo to further improve sound.

How to Order Your Quadraspire Rack

Quadraspire is a modular equipment racking system, therefore racks of various sizes and configurations can be built, much like Legos. Many parts are interchangeable within a series of products, i.e. SV/SVT products and Q4/Q4Evo products. In addition, your rack can be upgraded to higher levels of sonic performance. This guide will show you how to build a basic rack and demonstrate the modular concept.

Panda Friendly

Bamboo, lauded by many as the “Material of the Future”, is perfect for the manufacture of Quadraspire furniture.With its high tensile strength and vibration suppressing qualities, it further improves sound quality over traditional MDF. Its natural beauty, sustainability and eco-friendliness are sure to please discerning audiophiles and environmentalists alike.

The Quadraspire Method

As beautiful from below as it is from above.

For 20 years, Quadraspire has crafted modular furniture systems around a lightweight, rigid design philosophy.The concept is simple- create furniture that looks appealing and heightens the performance of HiFi audio systems. Doing that, while offering quality UK manufacturing and reasonable prices, is what Quadraspire is all about.

Quadraspire continues to please the eye and delight the ear.

Step One: Choose your performance level. Q4 Evo (good), SVT/2T (better), X-Reference (best). Splitting your equipment across multiple racks can improve performance (sources and preamps in one, amplification and power in another). Each individual rack requires a foot/cap set for the bottom shelf. Keep racks as short as possible for maximum stability.

 

 

Step Two: Decide how many shelves you need per complete rack. Each component should have a shelf, if possible. Columns should be selected to allow proper space for ventilation and isolation from stray RF and other electronic noise. Be mindful that components with fixed cabling may limit space between shelves.

Step Three: Pick the shelf color or material, and hardware color. Bamboo shelves are slightly thicker than standard Q4 Evo, and slightly thinner than standard SVT/2T. Bamboo offers higher performance because of its low mass, high rigidity and naturally anti-resonant character. Due to the nature of real wood, finish can vary slightly shelf to shelf, and will change with age.

Step Four: You are ready to build! This might be a good time to consider performance additives such as the Bronze Upgrade kit or QX7 isolators. X-Reference performance can be further optimized with optional stainless steel or aluminum locators. An interactive product builder is available on the
