Solidsteel S3-5 Five-Shelf Audio Rack - Walnut

The Solidsteel S3 — Italian Engineering, Built Around What You Put On It

Solidsteel has been making audio supports in Italy for more than twenty years, and the S3 is where that experience meets a real-world budget. Anodized aluminum columns, powder-coated steel, and shelves cut from laminated MDF, sized for full-width components.

What separates it from furniture is what happens inside the columns. Each one is filled with damping material, so the structure under your system has somewhere to send the vibration it picks up, instead of handing it straight back to the components.

Will Your Tallest Component Fit?

Every shelf measures 580 by 430 millimeters — about 22.8 by 16.9 inches — and is 30 millimeters thick. The top platform gives you that full width. Between the lower shelves the columns bring the usable span to about 19.7 inches, which is still wider than the great majority of full-size components.

Set the Shelves Where Your Amplifier Needs Them

This is the part that decides whether your amplifier goes in. Shelf positions adjust from 145 to 365 millimeters apart — 5.7 to 14.4 inches — so a tall tube amplifier or a stacked pair of small boxes can have the room it needs, taken from a shelf that does not.

Put Your Heaviest Amplifier on Any Shelf

Each shelf carries up to 60 kilograms, or 132 pounds. That is a serious power amplifier per level, not a nominal figure, and it comes from columns that thread together rather than welded joints that flex.

It Grows With the System

The S3 is built to be added to. An inner shelf and a set of four poles turn a three-shelf rack into a four, or a four into a five, using the same hardware the rack was assembled with — so the rack you buy now is not the rack you are stuck with.

Your Turntable Goes on the Top Shelf

Always. The top platform has nothing above it, so a dust cover opens freely, and it is the one position where the deck sits farthest from everything else that vibrates. It is also the widest surface on the rack. Browse our turntables for the deck to put there.

How It Manages Vibration

Floors carry vibration. Speakers put it into the room, the room puts it back into the floor, and whatever your components stand on either passes it along or gives it somewhere to go. That is the whole argument for a proper rack rather than a shelf.

Why These Columns Don't Ring

The S3's support poles are anodized aluminum, and each is filled internally with sound-absorbing damping material. A hollow tube rings; a filled one does not. That is the difference between a structure that stores vibration and one that drains it away.

Spikes, and Something to Stand Them On

Adjustable stainless steel spikes on M8 threads couple the rack to the floor and level it on boards that are never quite flat. Stainless steel floor-protective discs come in the box, so the spikes can do their job on a wood floor without marking it.

Mass in the Right Places

Galvanized steel under powder coating, anodized aluminum columns, laminated MDF shelves. Three materials with three different resonant behaviors, which is the point — no single frequency finds the whole structure sympathetic, so nothing rings in unison.

Keeping Your Components Cool

An open frame lets air move freely around every side of a component, which is something no closed cabinet can offer. Amplifiers and streamers shed heat upward and sideways, and here there is nothing in the way of either.

The adjustable spacing matters here too. A class-A amplifier that runs warm can be given 14.4 inches of clear air while a thin streamer takes 5.7, rather than every component getting the same gap whether it needs it or not.

You Can Build It by Hand

The columns thread into the shelves by hand and the spikes screw into the column ends. Solidsteel publishes an official installation guide, linked below, and the sequence is worth watching once before you start — assembling each shelf's hardware upside down first makes the whole job quicker.

Level it with the spikes before anything goes on the shelves, not after. A rack that starts level stays level once it is loaded, and the spikes are far easier to reach with nothing standing on top of them.

Where It Will Live in Your Room

Black and walnut, both on the same structure. The lines are plain enough to sit quietly beside most furniture, which is usually what you want from something holding several thousand dollars of electronics.

Who Is the Solidsteel S3 Best For?

• You want a support engineered rather than styled — damping-filled aluminum columns and 132 pounds a shelf come from an audio company, not a furniture maker.
• Your components are different heights — adjustable spacing from 5.7 to 14.4 inches means the tall amplifier and the slim streamer each get what they need.
• You run a turntable — the top platform is the widest surface on the rack, with nothing above it to limit a dust cover.
• Your gear runs warm — an open frame puts air on every side, and you choose how much sits above anything that needs it.
• You expect the system to grow — add a level whenever you need one with an S3 inner shelf and a set of four poles from our add-on shelves.

Pairs Well With

A rack is the foundation; these are what usually go on it and under it:

• Isolation feet or platforms — the S3 handles what comes up through the floor, and these address what a component generates on its own.
• A turntable — the top platform is sized and sited for one.
• Interconnect cables — components spread over several levels need longer runs than a single shelf does.
• An add-on shelf and poles — the way an S3 grows a level at a time instead of being replaced.

Frequently Asked Questions

Will my tall amplifier fit?

Almost certainly. Shelf positions adjust from 145 to 365 millimeters apart, which is 5.7 to 14.4 inches of clear height. Measure your tallest component, add room for air above it, and set the shelf to suit.

How much weight will each shelf hold?

Sixty kilograms, or 132 pounds. That is per shelf, and it is the figure Solidsteel publishes for the S3 — a step up from the 110 pounds per shelf of the S2 series.

Can I add a shelf later?

Yes. An S3 inner shelf and a set of four poles with hardware will take a three-shelf rack to four, or a four to five. The parts are the same ones the rack was built from, so the result is a factory rack rather than a modification.

How hard is it to assemble?

The columns thread into the shelves by hand and the spikes screw into the ends. Solidsteel publishes a step-by-step installation guide, which is embedded above — watch it once and the sequence is obvious.

Where should the turntable go?

On the top platform. Nothing sits above it, so the dust cover opens freely, it is the widest surface on the rack, and it puts the deck as far as possible from everything else.

What comes in the box besides the rack?

Adjustable stainless steel spikes on M8 threads, and a set of stainless steel floor-protective discs so the spikes can be used on a finished floor. The hardware to assemble it is included.
