Solidsteel Hyperspike HF-2 Two-Shelf Audio Rack - Gloss Black

The Solidsteel Hyperspike HF — Where Every Upright Ends in a Spike

Most racks bolt their shelves to a frame. On a Hyperspike the uprights carrying each platform end in a point, and that point sits in a dimple in the upright below it. The rack is a stack of separate levels meeting at contact points rather than one welded structure.

That idea is what the range is named after, and it is carried through to the floor, where four large spikes do the same job between the rack and your room. This is the top of Solidsteel’s line, made by hand in Italy.

Will It Hold What You Have Bought?

The Bottom Shelf Is Built for a Power Amplifier

The lowest bay has 12 inches of clear height where the levels above it have 8. Reviewing the HF-4 for hi-fi+, Alan Sircom called that bottom shelf “power-amp friendly,” which is exactly what it is for: the heaviest, hottest box in the system goes at the bottom.

Thirty Millimeters of Shelf Under Your Gear

The lacquered MDF platforms are 30 millimeters thick, which is close to an inch and a quarter and roughly double what most racks use. Each one carries up to 176 pounds, and that figure is the same on the top shelf as on the bottom.

Room for Gear That Ignores Standard Sizes

These are the largest shelves Solidsteel makes. The top platform is 25.4 inches wide and 22.1 deep, with 21.1 by 22.1 inches usable on the levels below. That depth is the point — esoteric components rarely respect a standard chassis footprint.

Add a Level as the System Grows

The HF is modular, so a rack gains shelves rather than being replaced. A level needs an inner shelf and a set of four 8-inch polished steel posts with hardware. Call us on 800-942-0220 and we will confirm the shelf in the finish you own.

Where the Uprights Meet, and Why It Matters

A floor carries vibration upward and speakers put more of it into the room. A rack either hands that on to the components or gives it somewhere else to go. The Hyperspike system makes its argument at the joints rather than in the materials.

A Spike Into a Dimple, at Every Joint

Each shelf’s uprights end in an adjustable spike with a locking mechanism, seated in a dimple in the upright beneath. Contact between levels happens at four points instead of across flat faces, so every shelf is isolated from the one under it rather than bolted to it.

O-Rings Between the Shelves

Rubber O-rings sit at those junctions, working much as piston rings do — tightening the fit while cutting what passes across it. Solidsteel calls the whole arrangement the Hyperspike Vibration Free System, and it is the reason the range exists.

Four Spikes, and the Cups That Go Under Them

At the floor, four large spikes carry the whole rack on minimal contact. Four metal cupped feet are supplied with it, and on a suspended wooden floor those are what you want under the spikes rather than the spikes themselves in the boards.

Nothing Boxes the Amplifier In

There is no back, no side panel and no door anywhere on this rack. A power amplifier on the bottom shelf sheds heat upward and sideways into open air, which is the one thing a closed cabinet cannot offer whatever is cut into its panels.

The 12-inch bottom bay helps twice over. It takes a tall chassis, and it leaves genuine clearance above a component that runs hot rather than the minimum a shelf spacing happens to allow.

Set It Level Once and Leave It

The rack goes together as a bolt-together frame, and Solidsteel publishes a step-by-step installation guide for the series, embedded below. Watch it before opening the carton and the order of operations makes sense from the start.

Level it on the spikes before anything goes on the shelves. These are heavy platforms and a fully loaded HF is not something you want to lift to reach a foot underneath, so getting it right while it is empty is time well spent.

Think about the floor as well as the rack. Loaded to capacity this is a great deal of weight standing on four points, so on older suspended floorboards use the supplied cups and choose a spot over a joist rather than mid-span.

It Is Meant to Be Looked At

The tubular supports are solid INOX stainless steel, an inch and a half across, polished rather than painted. Set against gloss black or gloss white lacquered shelves with rounded, corner-free edges, the frame is the part you see, and it has been finished accordingly.

Both finishes run on the same steel, so the choice is about what the room wants. This is a rack designed to be seen with the equipment on it, not one meant to disappear behind a door.

What Reviewers Are Saying

Alan Sircom, reviewing the HF-4 for hi-fi+: “Solidsteel has long been the choice of audio manufacturers at shows and demonstrations worldwide to show off their products in as neutral a way as possible, for good reason.”

On the rack itself he was direct. What it does, he wrote, is “inspire confidence” — set and leveled, it goes nowhere. He put much of its mass down to the 30mm shelves rather than the steel.

Who Is the Solidsteel Hyperspike HF Best For?

• You own a serious power amplifier — the bottom bay gives 12 inches of clear height and 176 pounds of capacity, with no need to hunt for a shelf that will take it.
• Your components are not standard sizes — these are the largest shelves Solidsteel builds, 22.1 inches deep, for gear that ignores the usual footprint.
• You want the joints doing the work — spikes into dimples and rubber O-rings at every level, rather than shelves bolted to a single welded frame.
• The rack will be seen — polished INOX uprights and gloss lacquered shelves, made by hand in Italy and finished to be looked at.
• You want to go further under the source — the platforms are neutral enough that isolation feet sit on top of them cleanly.

Pairs Well With

• HF-Series 8-inch post kit — four polished steel posts with hardware, the other half of adding a level to a rack you already own.
• Isolation feet and platforms — between a source and its shelf, on a platform neutral enough to make the difference audible either way.
• A turntable — the top platform is the widest surface on the rack and has nothing above it, which is where a deck belongs.
• Interconnects — work your runs out from where each component will actually sit, since the bottom bay is deeper than the rest.

Frequently Asked Questions

How much weight will each shelf hold?

A maximum of 176 pounds, which is 80 kilograms, and the figure applies to every shelf including the top. The platforms themselves are 30 millimeters of lacquered MDF.

Will my power amplifier fit on the bottom shelf?

The bottom bay has 12 inches of clear height against 8 inches for the levels above it, and it is sized deliberately for a large amplifier. Check your chassis width against the 21.1 inches usable between the uprights.

What does the Hyperspike name mean?

Each shelf’s uprights end in a locking adjustable spike that seats into a dimple in the upright below, and four larger spikes carry the rack at the floor. Levels meet at points rather than across flat faces.

Can I add a shelf later?

Yes. A level takes an inner shelf and a set of four 8-inch posts with hardware. Call us on 800-942-0220 before ordering and we will confirm the inner shelf available in the finish you have.

Will it damage my floor?

Four metal cupped feet are supplied to sit under the spikes, which is what you want on hardwood, tile or a suspended floor. Fully loaded this rack carries real weight on four points, so use the cups and pick a solid spot.

What is the difference between the gloss black and gloss white versions?

The shelf lacquer, and nothing else. Both run on the same polished stainless steel uprights with the same dimensions, the same capacity and the same hardware.
