Reference Audio Equipment Isolation & Resonance Control | Brisbane HiFi Specialist The Nordost Sort Kone is a directly coupled mechanical resonance control device engineered to provide a controlled mechanical path between sensitive audio equipment and its supporting surface. Unlike conventional soft isolation feet or rubber pads that absorb and potentially reflect mechanical energy, the Sort Kone functions as a mechanical ground, directing unwanted chassis vibration and resonance away from sensitive electronics. Placed beneath components such as CD players, DACs, streamers, preamplifiers, phono stages, power amplifiers, and power distribution equipment, Sort Kones are designed to improve system focus, transparency, imaging, and low-level detail retrieval. At Brisbane HiFi, we recommend Nordost Sort Kones for audiophiles seeking to optimize the mechanical environment of their existing HiFi electronics across Brisbane, Queensland, and Australia. Key Features & Audio Engineering Highlights Direct Mechanical Grounding The Sort Kone bypasses conventional equipment feet to establish a direct mechanical path between the component chassis and supporting rack surface. Designed to help control: Chassis vibration Mechanical resonance Transformer vibration Microphonic interference Internal Mechanical Damping The three-piece construction incorporates: Post Base Internal coupling sphere The mechanical interface is designed to control structural energy while maintaining a rigid coupling path. Reduction of Mechanical Interference By controlling unwanted vibration around sensitive electronics, the Sort Kone is designed to improve: Background clarity Micro-detail retrieval Stereo imaging Dynamic focus Acoustic transparency Flexible 3- or 4-Point Configuration Sort Kones can be positioned beneath compatible equipment in three- or four-point configurations, allowing the support arrangement to be optimized for: Chassis size Equipment weight Weight distribution Transformer location Four Material Performance Tiers AS — Aluminum / Steel Features an aluminum post and base with a hardened steel internal coupling ball. AC — Aluminum / Ceramic Combines aluminum construction with a Si₃N₄ ceramic coupling ball for fast mechanical energy transfer. BC — Bronze / Ceramic Uses bronze construction with a ceramic coupling ball, providing a different mechanical and tonal character. TC — Titanium / Ceramic Features titanium construction with a ceramic coupling sphere, designed for maximum speed, dynamic precision, and transparency.
