Quadraspire SVT Bronze Upgrade Spikes (Set of 4)
To celebrate the twentieth anniversary of the Q4 hifi rack Quadraspire have developed the Bronze upgrade that can be easily retro fitted to any Q4 or SVT rack or wall shelf. Bronze has a broader tonal spectrum and greater sustain that opens the soundstage of your system making it more musical and enjoyable without losing detail.
All Quadraspires racks are designed to be light and rigid to deliver a clearer, cleaner musical performance. This is achieved by combining Wood or Bamboo shelving with solid Aluminium columns & feet. The advantages of Aluminium are its low weight, high strength and nonmagnetic properties as well as being a good thermal and electrical conductivity. Quadraspire wanted to find out what other metals do, so they carried out a lot of research into the composition of other metals such as Stainless Steel, Titanium, Brass and Bronze.
Central to all their research was extensive listening tests using the tried and tested technique of tuning by ear in the same way as the finest musical instruments are developed. In fact Bronze is one of several high copper content alloys used as a substitute for the more common types of brass to construct the bodies and bells of metal wind instruments. Even some instrument strings for acoustic guitars, mandolins and violins are wrapped with bronze. In addition to the distinctive appearance provided by the reddish-orange hue of bronze, it provides a broader harmonic response spectrum for a given instrument design.
The main design features of the Bronze upgrade spike assembly are the SVT curve design of the top bolt and the rounded spikes that together encourage any residual mechanical resonance to flow and dissipate more easily. The assembly consists of a Top Bolt and Lock nut and then a small rounded spike and smaller locknut that screws into the top bolt – all engineered at their factory south of Bath. The upgrade can be easily fitted to the top shelf of your rack or Wall bracket for the benefit of the source component placed onto that shelf.
Any component placed on a shelf fitted with the bronze upgrade will have a noticeable improvement, music becomes more open and involving without loss of detail.
