the HiFi performance upgrade

Give your HiFi the support it needs to sound its very best

Where you place your HiFi has a real impact on what you hear. Quadraspire performance HiFi racks are designed to help you get more from your system by reducing resonance, lowering the noise floor and opening up the soundstage, so you can enjoy greater clarity, more detail and a more immersive listening experience.

To celebrate twenty years of the iconic Q4 Evo HiFi rack, we introduced the bronze Upgrade, a simple way for you to enhance any Q4 Evo or SVT HiFi rack or wall shelf. Selected for its broader tonal spectrum and greater sustain, bronze helps your system create a more open soundstage, bringing added richness, musicality and enjoyment to every track you play.

Our research was guided by extensive listening and tuning by ear, the same trusted approach used in creating the finest musical instruments. That is one reason bronze stood out as such a natural choice. This high-copper alloy is prized for its rich harmonic qualities and is widely used in metal wind instruments and the strings of acoustic guitars, mandolins and violins. In your HiFi system, those qualities help reveal more depth, texture and natural musical expression, making your listening experience feel even more engaging.
