High fidelity (Hi-Fi) sound systems aim for quality sound reproduction with minimal distortion, mirroring original recordings. Equipment racks enhance these systems by isolating components from vibrations that can affect sound clarity. Hi-Fi racks utilise varying materials for vibration absorption, structural integrity, and aesthetic qualities. Solid woods improve acoustic performance by absorbing vibrations, metals provide sleekness and durability, and tempered glass offers a modern look without compromising sound.
