The HP-3 sits within Solidsteel’s Hyperspike Prestige Series — the Italian manufacturer’s flagship range of ceramic audio racks. Where Solidsteel’s other ranges such as the S-Series and HF-Series use MDF shelves with polymer laminate or lacquered finishes, the HP-Series introduces premium ceramic slab construction for superior vibration damping and rigidity.
Ceramic Shelf Construction
Each shelf comprises a 5mm ceramic slab bonded to a 25mm core of medium/high-density polyurethane foam and wood fibres, finished with 25mm resin edges. The ceramic surface is scratch-proof, while the foam-and-fibre core provides internal damping that absorbs resonance before it can reach the equipment above. This hybrid construction combines the mass and inertness of ceramic with the energy-dissipating properties of foam — a fundamentally different approach to the MDF shelves used elsewhere in the range.
Stainless Steel Hyperspike Frame
The frame is built entirely from 39mm-diameter stainless steel (INOX) tubing, liquid-painted in either a Brass or Copper finish. Solidsteel’s Hyperspike system uses precision-turned stainless steel spikes at each shelf junction, decoupling each level mechanically. Between the spikes and the shelves, 3D-printed recyclable rubber isolation discs provide a further layer of vibration control, preventing energy transfer between the frame and the ceramic surfaces.
Practical Design
The HP-3 provides three shelves with clearances of 315mm and 215mm between levels, accommodating standard-height hi-fi separates on the upper shelf and smaller components below. Each shelf supports up to 90 kg. The modular Hyperspike design allows future expansion — additional shelf modules can be added without compromising the mechanical integrity of the rack.
