Solidsteel Hyperspike HY-4 Four-Shelf Audio Rack

Best Audio Racks 2025 - Robb Report

Enjoy A Significant Sonic Improvement with Your AV Gear

Give your AV system a lift with this affordable high-end rack from Solidsteel. Premium materials and two kinds of decoupling on each shelf allow your electronics to perform at their best. Turtables particularly love the four-shelf Hyperspike HY-4, but it can enhance the sound of all your audio gear.

"How do you grade an equipment rack for its sound quality?" asks Mark Gusew in his February 7, 2020 StereoNet review of the HY-4. "Well, I came away confident that the Solidsteel rack contributed to my reference system's overall performance significantly, and I am sure that many audio manufacturers – and indeed exhibitors at hi-fi shows – will agree."

The HY-4 is 35" tall, 23.6" wide, and 19.7" deep. Usable shelf dimensions are 23.6" wide, 19.7" deep for the top shelf and 20" wide, 19.7" deep for the lower shelves. The distance between first and second shelf is 7.3" – between the second and third shelf is 7.3" - and between the third shelf and the fourth shelf is 11.2". The distance between the fourth shelf and the floor is 3.9". The weight capacity is a maximum of 155 lb. per shelf.

Award-Winning Performance

The Solidsteel HY-Series grabbed the Best Audio Racks Award 2025 from the Robb Report.

"Finding the right furniture for audio components is a challenge… Enter Italy’s Solidsteel, audio furniture that has stood the test of time, not just with practical performance, but with aesthetics befitting the best gear placed atop their thick shelves."

"Machined steel legs and damped supports in black, wood, or even marble complement any environment, and allow users the freedom to adjust height based on clever extensions to individual legs. The HY (Hyperspike) Series – our favorite based on its Le Corbusier looks and true functionality – hits a sweet spot."

"Well Able to Sink Unwanted Vibrations"

"Due to its top-class design, and its weight and overall rigidity, there was no discernible colouration from the HY-4," reports Mark Gusew at StereoNet. "This held true even when listening at high volume levels or playing music with particularly heavy bass. It seemed well able to sink unwanted vibrations."

This stunning four-shelf rack features stainless-steel frames made of 1.5"-diameter tubes, providing rock-solid support for black-lacquered MDF shelves. The modular design lets you combine HY racks to expand your storage capability as your system grows.

For maximum control of floor-borne and component-generated vibration, each shelf features precision cone point isolation feet for decoupling from the shelf below, plus internal decoupling pins. The rack floor feet use height-adjustable spikes plus included floor-protection discs.

Acoustical Research and Innovation

Since its first official launch in 2006, the Hyperspike series racks have occupied the top tier of Solidsteel AV racks. The Hyperspike series marries our premium Italian design to acoustical research and innovation, making these racks famous worldwide.

In 2018, Solidsteel's new HY series Hyperspike racks wrote a new chapter of the company's esteemed history as Europe's premier AV rack architect. Solidsteel defines the HY series as one of "Functional Beauty," in which the performance enhancing features are accented in an arresting, eye-catching design that absolutely exudes quality on every front.

Despite the high-end performance, these racks offer exceptional value for the money. The HY series is an evolution of the bestselling Hyperspike Junior (HJ Series) models, which for decades have offered the benefits of Hyperspike stands at affordable prices.

Best Audio Racks 2025 - Robb Report

"Finding the right furniture for audio components is a challenge. The best – Harmonic Resolution Systems, without debate – can be as costly as most gear itself, while inexpensive racks don’t provide the stability and vibration isolation needed, especially when stacking three or four shelves high."
