Solidsteel Hyperspike HY Series 4 Large Shelf Rack

Four-Tier Extra-Wide Reference Decoupled Audio Rack | Brisbane HiFi Audio Specialist The Solidsteel HYL-4 is a four-tier extra-wide equipment rack from Solidsteel's reference Hyperspike (HY) Series, designed for comprehensive high-end audio systems requiring substantial horizontal platform area alongside multiple equipment levels. Handcrafted in Italy, the HYL Series combines solid stainless-steel structural elements with Hyperspike-inspired mechanical-support architecture and an expanded 790 mm-wide footprint. With a usable shelf area of 690 × 500 mm and a specified 80 kg load capacity per shelf, the HYL-4 provides four substantial platforms for large-format turntables, wide-chassis electronics, side-by-side components, substantial amplification, and external power supplies. At Brisbane HiFi, we recommend the HYL-4 for extensive reference systems where both horizontal platform area and multi-tier equipment capacity are important considerations. Key Features & Mechanical Engineering Highlights Extra-Wide 790 mm Architecture: The extended frame provides substantial horizontal space for oversized components, wide-format sources, and large turntables. 690 × 500 mm Usable Shelf Area: Each platform provides considerable flexibility for large equipment and compatible side-by-side component arrangements. Hyperspike-Inspired Decoupling Architecture: Solid stainless-steel structural elements and precision mechanical interfaces provide controlled support for sensitive audio equipment. 30 mm Heavy-Duty MDF Shelves: Dense MDF platforms provide high-mass mounting surfaces with durable polymer laminate finishes. 80 kg Load Capacity Per Shelf: Each level is rated for up to 80 kg, giving the four-shelf configuration a specified combined shelf capacity of 320 kg. Solid Stainless-Steel Pillars: Stainless-steel support elements provide a rigid structural foundation for the wide-format rack. 285 mm Lower-Level Clearance: The generous lowest equipment space accommodates large power amplifiers, valve electronics, turntables, and substantial power supplies. 185 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. Modular HYL Architecture: Compatible HYL Series shelf kits allow the rack to expand as equipment requirements develop.

A possible configuration could be: Top Shelf: Large Turntable + Phono Stage / Wide Digital Source Second Shelf: Preamplifier + Network Streamer Third Shelf: DAC + Digital Transport Bottom Shelf: Power Amplifier + Power Supply The 690 × 500 mm usable platform provides considerable freedom for large components and associated electronics, subject to individual equipment dimensions, weight, and ventilation requirements. Wide-Format Turntable Integration The spacious upper platform is particularly suited to large-format turntables and analogue systems with substantial footprints. Brisbane HiFi can assist with: Rack levelling Turntable positioning Mechanical isolation Tonearm cable routing Cartridge-system planning Component placement Floor-vibration considerations Heavy-Component Load Planning With an 80 kg capacity per shelf and 320 kg total specified shelf capacity, the HYL-4 is designed for substantial equipment loads. Brisbane HiFi can assist with: Equipment weight assessment Horizontal and vertical load distribution Component dimensions Amplifier ventilation Side-by-side equipment placement Power-supply positioning Cable routing Future expansion Large heat-generating components should retain the ventilation clearances specified by their manufacturers. Home Audio & AV Applications The HYL-4's generous horizontal platforms can also be useful in combined audio-visual installations where multiple wide-format components need to be consolidated into a single furniture structure. Potential applications include: Large stereo systems Wide-format AV electronics Multiple source components Large integrated amplifiers Power amplifiers External power supplies Combined analogue and digital systems Any display or loudspeaker installed on or around the rack should be independently assessed for dimensions, weight, stability, and manufacturer requirements. Modular Expansion The HYL-4 is built around Solidsteel's modular architecture and can be expanded using compatible HYL Series shelf kits. This allows the equipment furniture to evolve alongside a growing system while retaining its wide-format platform architecture. HYL-4 vs HY-4 The HYL-4 retains the substantial four-tier architecture of the HY-4 while increasing the horizontal platform area and load capacity: HY-4 HYL-4 Overall Width 600 mm 790 mm Usable Shelf Width 500 mm 690 mm Usable Depth 500 mm 500 mm Load Capacity 70 kg/shelf 80 kg/shelf Total Shelf Capacity 280 kg 320 kg Lower Clearance 285 mm 285 mm Upper Clearances 185 mm 185 mm The HYL-4 is suited to systems where the additional horizontal space and higher shelf loading are important considerations.
