Solidsteel Hyperspike HF Series 4 Shelf Rack

Four-Tier Flagship Hyperspike Decoupled Audio Rack | Brisbane HiFi Audio Specialist The Solidsteel HF-4 is a four-tier reference equipment rack from Solidsteel's flagship Hyperspike High-End (HF) Series, designed for extensive high-end audio systems requiring substantial equipment capacity and advanced mechanical support. Handcrafted in Italy, the HF Series combines 39 mm solid stainless-steel structural pillars, substantial 30 mm MDF platforms, and precision mechanical-support hardware to provide a rigid foundation for sophisticated analogue and digital systems. With a specified 80 kg load capacity per shelf, 320 kg total shelf capacity, and generous 535 × 500 mm usable shelf dimensions, the HF-4 provides four substantial platforms for turntables, DACs, network streamers, preamplifiers, phono stages, amplifiers, and power supplies. At Brisbane HiFi, we recommend the HF-4 for extensive reference systems requiring four dedicated equipment levels while retaining the substantial construction and mechanical architecture of the flagship HF Series. Key Features & Mechanical Engineering Highlights Hyperspike Decoupling Architecture: Incorporates solid stainless-steel structural elements, precision mechanical interfaces, and decoupling hardware derived from Solidsteel's Hyperspike design philosophy. 39 mm Solid Stainless-Steel Pillars: CNC-machined 39 mm INOX structural pillars provide a substantial rigid framework for the four-tier rack. 30 mm Heavy-Duty MDF Shelves: Dense MDF platforms provide substantial mounting surfaces with premium polymer laminate or real-wood veneer finishes. 80 kg Load Capacity Per Shelf: Each level is rated for up to 80 kg, giving the complete rack a specified combined shelf capacity of 320 kg. 535 × 500 mm Usable Platforms: Generous shelf dimensions provide substantial space for large source components, amplification, and power supplies. 305 mm Lower-Level Clearance: The lowest equipment level provides additional room for large power amplifiers, valve electronics, and substantial power supplies. 205 mm Upper-Level Clearances: The three upper equipment levels provide useful space for DACs, streamers, preamplifiers, phono stages, and other source components. Adjustable Stainless-Steel Spikes: Precision-adjustable floor spikes allow accurate levelling and establish a defined mechanical interface with the supporting floor. Protective S Series Floor Pads: Included floor discs help protect timber, laminate, tile, and other finished flooring from spike contact. Fully Modular Construction: Compatible HF Series shelf kits allow the rack to be expanded or reconfigured as the system develops.
