Quadraspire
Q4 EVO
The Q4 EVO is Quadraspire's modular UK-built hi-fi rack, combining 32mm-diameter curved aluminum columns with solid bamboo-ply shelves that are CNC-machined with intricate grooves on their underside to reduce resonance and dissipate energy, an evolution of the company's original 1995 Q4 design. The rack builds up tier-by-tier from a wide range of column heights and bamboo or wood-veneer finishes, using a low-mass approach — aluminum columns to eliminate residual magnetism and self-damping wood shelves — rather than high-mass damping to control vibration.
