Audio T Verdict
The Solidsteel S5-5 is the largest standard rack in the S5 family, combining five individual equipment levels with the range's more sophisticated decoupled shelf construction. It is designed for systems where the box count has grown substantially but equipment support and vibration management remain just as important as sheer capacity.
Each level uses a separate secondary equipment platform supported above the main structural shelf through dedicated decoupling points. The aluminium uprights are internally filled with StratoCell damping material too, giving the S5 a more technically involved approach than Solidsteel's conventional S3 furniture.
The important thing to understand is the standard shelf spacing. To accommodate five levels without making the rack excessively tall, the S5-5 uses four equal 185mm equipment intervals. That is excellent for streamers, CD players, DACs, preamplifiers, phono stages and other conventional-height separates, but large integrated and power amplifiers need particularly careful checking.
If you genuinely need five equipment levels and most of the system uses relatively low-profile electronics, the S5-5 offers a lot of capacity within a conventional 584mm-wide footprint. If one large amplifier needs considerably more vertical room, however, the S5-4 may actually be the better fit despite having one fewer shelf.
185mm Shelf Spacing Needs Careful Checking
The standard S5-5 provides four approximately 185mm equipment intervals. This is less vertical space than the S5-4, S5-3 and S5-2. Large integrated amplifiers, power amplifiers, valve amplifiers and hot-running Class A designs may not have sufficient ventilation within an enclosed level even if the chassis itself physically fits.
Solidsteel S5-5 Five-Shelf Hi-Fi Rack
The Solidsteel S5-5 is the five-level model within Solidsteel's current S5 Series of advanced specialist hi-fi racks.
Designed and manufactured in Italy, the S5 Series combines modular aluminium construction with a distinctive two-level decoupled shelf arrangement intended to provide audio components with stable, purpose-designed mechanical support.
The S5-5 provides five equipment platforms with four equal approximately 185mm standard intervals, making it particularly well suited to larger systems built around conventional-height source and control components.

Five Equipment Levels
The S5-5 provides the greatest number of equipment platforms in the standard S5 range.
Five levels can be particularly useful for systems containing combinations such as:
- Turntable, phono stage, streamer, CD player and integrated amplifier
- Turntable, phono stage, preamplifier, power supply and power amplifier
- Network transport, DAC, preamplifier, power supply and power amplifier
- Streamer, CD player, DAC, headphone amplifier and integrated amplifier
- Several analogue and digital sources feeding a common amplifier
Every major component can receive its own equipment platform rather than being stacked directly on another chassis.
Advanced Two-Level Decoupled Shelf Design
The most important difference between the S5 and a conventional hi-fi rack is the construction of each equipment level.
The main shelf provides the structural foundation, while the component itself sits on a separate secondary platform positioned above it.
Dedicated mechanical contact points sit between these two surfaces, introducing a controlled interface rather than rigidly coupling the equipment platform across the entire structural shelf.
What Is a Decoupled Hi-Fi Shelf?
A decoupled shelf separates the surface directly supporting the hi-fi component from the main rack structure through defined mechanical contact points. The aim is to reduce direct transmission of unwanted mechanical energy while retaining a stable supporting platform.
Reinforced Main Shelves
The primary structural shelves feature perforated central areas and reinforcing elements as part of Solidsteel's S5 design.
These provide the structural foundation of each level, while the secondary shelf above carries the actual hi-fi component.
Separating those two functions allows Solidsteel to introduce its additional mechanical decoupling stage between the equipment and rack.
Secondary Equipment Platforms
The secondary platforms are supported through dedicated decoupling cones.
These defined contact points form the mechanical interface between the equipment surface and structural shelf beneath it.
This arrangement is the principal reason for moving from Solidsteel's conventional S3 furniture to the more advanced S5 range.
Why Can Hi-Fi Equipment Support Matter?
A listening room contains numerous potential sources of mechanical energy.
These can include:
- Loudspeakers
- Subwoofers
- Footfall
- Suspended floors
- Turntable motors and bearings
- CD and disc mechanisms
- Transformers inside amplifiers and power supplies
No rack can completely isolate equipment from everything happening around it, but specialist furniture can provide a stable, level and deliberately engineered mechanical support.
Particularly Relevant for Turntables
Solidsteel specifically recommends the S5 Series for turntable owners.
A turntable is mechanically sensitive by its very nature. The stylus is intended to respond to tiny movements in the record groove, making unwanted movement entering through the supporting furniture worth controlling wherever practical.
The completely open top level of the S5-5 provides an obvious place for a record player while leaving four further platforms for the rest of the system.
Floor-Borne Vibration Still Depends on the Room
A specialist rack can provide a much more considered equipment support, but severe footfall on a flexible suspended floor may still be better addressed with a properly installed turntable wall shelf fixed to a suitable structural wall.
Four Equal 185mm Equipment Intervals
The standard S5-5 uses four approximately 185mm gaps between its five equipment platforms.
This makes the rack particularly suitable for conventional-height electronics such as:
- Network streamers
- CD and SACD players
- Digital transports
- DACs
- Preamplifiers
- Phono stages
- Headphone amplifiers
- Tuners
- External power supplies
- Compact integrated amplifiers
Will My Amplifier Fit?
The S5-5 needs more careful amplifier matching than the shorter S5 models because every standard enclosed interval is approximately 185mm high.
When checking an amplifier, consider:
- Overall chassis height
- Height including equipment feet
- Top-panel ventilation openings
- Heatsinks
- Manufacturer-recommended cooling clearance
- Normal operating temperature
Physical Fit Is Not Enough
An amplifier measuring 170mm high may technically fit within a 185mm opening but would leave almost no room for heat to escape. Never treat the published shelf clearance as the maximum safe amplifier height without checking the manufacturer's ventilation requirements.
The Open Top Platform
The uppermost equipment platform has unrestricted space above it.
This can be particularly useful for:
- Turntables
- Tall integrated amplifiers
- Power amplifiers
- Class A amplifiers
- Valve amplifiers
- Equipment exceeding the 185mm enclosed shelf height
If a large amplifier is the only tall component in the system, positioning it on the open top may be more practical than trying to fit it within one of the standard enclosed intervals.
A Five-Box Vinyl System
The S5-5 is particularly useful when a vinyl-based system has evolved beyond a simple turntable and integrated amplifier.
One possible configuration could be:
- Top: turntable
- Level 2: phono stage
- Level 3: network streamer
- Level 4: preamplifier
- Level 5: power supply or suitable amplification
The precise layout should always be determined by dimensions, ventilation and ease of use rather than by a fixed rule about which component belongs on which level.
Ideal for Multi-Box Digital Systems
Five levels are equally useful with more complex digital systems.
For example:
- Network transport
- DAC
- CD transport
- Preamplifier
- External power supply or suitable power amplifier
Each major component receives its own dedicated support surface.
Avoid Stacking Components
A five-level rack removes much of the temptation to stack one component directly on another.
Stacking equipment can introduce several avoidable problems:
- Restricted ventilation
- Heat transfer between chassis
- Additional load on lower components
- Difficult access to connections
- Direct mechanical interaction between components
Providing each major component with its own platform is usually the cleaner solution.
Approximately 584mm Overall Width
The S5-5 retains the conventional-width footprint used throughout the main S5 rack family.
At approximately 584mm wide, it remains considerably narrower than specialist AV furniture and can fit comfortably into many conventional hi-fi installations.
Approximately 500mm Usable Equipment Width
The supporting structure occupies part of the overall rack width, leaving approximately 500mm of usable equipment space.
This is sufficient for most conventional full-width hi-fi components based around chassis widths of approximately 430mm to 450mm.
Use the Internal Width for Large Components
The rack itself is approximately 584mm wide, but unusually wide electronics should be checked against the approximately 500mm usable space within the supporting structure.
430mm Rack Depth
The S5-5 measures approximately 430mm front-to-back.
This comfortably accommodates many source components, although particularly deep amplifiers, power supplies and high-end electronics should be checked carefully.
Allow for Rear Connections
The quoted depth of a hi-fi component normally describes the chassis rather than its complete installed size.
Additional space may be needed for:
- IEC mains plugs
- Heavy mains cables
- RCA interconnects
- XLR connectors
- Speaker terminals
- Banana plugs and spades
- Network cables
- USB and HDMI connections
Check Installed Depth Rather Than Chassis Depth
A component approaching 430mm deep may need substantially more space once its rear connections are fitted. Allow enough room for cables to exit naturally without tight bends or excessive pressure on sockets.
55kg Capacity Per Equipment Level
Solidsteel's current specification rates each S5 equipment shelf for a maximum load of 55kg.
That is approximately 121lb per equipment level.
This comfortably covers the majority of turntables, source components, preamplifiers and integrated amplifiers.
The S5 Is About Decoupling Rather Than Maximum Load
The conventional S3 rack shelves are currently rated slightly higher at 60kg. The reason to move to the S5 Series is its more sophisticated two-level equipment support and decoupling architecture rather than simply increased carrying capacity.
MDF Equipment Platforms
The S5 shelf system uses high-quality MDF with a premium polymer-laminate finish.
MDF provides a relatively consistent engineered structure without the continuous natural grain found in solid timber, while the laminate gives the furniture a durable and uniform visible surface.
The standard S5 shelf finishes are not genuine wood veneer.
Anodised Aluminium Support Tubes
The rack structure uses anodised aluminium tubular supports.
Aluminium provides useful rigidity while keeping the complete structure more manageable than an equivalent rack constructed entirely from solid metal.
StratoCell Internal Damping
The aluminium support tubes are internally filled with StratoCell sound-absorbing material.
A hollow metal tube can itself exhibit resonant behaviour when exposed to mechanical energy. Internal damping is intended to help control that behaviour while retaining the structural rigidity needed to support the system.
What Is StratoCell?
StratoCell is the sound-absorbing material Solidsteel uses inside the aluminium support tubes of its current S Series furniture. Its role is to help damp resonance within the supporting structure.
Stainless-Steel Structural Components
Solidsteel specifies stainless steel for a number of important components within the current S5 structure.
These include:
- Upper terminations
- Lower terminations
- Adjustable floor spikes
- Protective floor discs
- Adjustable cones
- Fixing hardware
ABS Shelf Interfaces
ABS protective discs are incorporated at the shelf interfaces.
These create defined contact surfaces between different parts of the rack rather than allowing the MDF platforms to bear directly against surrounding metalwork.
Adjustable Floor Spikes
The S5-5 uses individually adjustable floor spikes so small variations in the underlying floor can be compensated for.
Correct adjustment helps ensure that the complete five-level structure sits securely rather than rocking between its support points.
Why Levelling Is Particularly Important on the S5-5
The S5-5 stands over a metre high and can become extremely heavy once five components are installed.
Accurate levelling helps provide:
- A stable equipment foundation
- Consistent floor contact
- Correct turntable setup
- Reduced rocking or movement
- A more secure tall equipment installation
Protective Floor Discs
Solidsteel supplies S Series protective floor discs for use beneath the rack's pointed spikes.
These should be used on timber, laminate, tile, stone and other surfaces that could otherwise be marked by direct spike contact.
Position the Rack Before Fully Loading It
The S5-5 weighs approximately 47kg before any equipment is installed. Once five components are added, moving the complete assembly can become difficult and potentially unsafe. Assemble, position and accurately level the rack before fully loading it wherever practical.
Fully Modular Construction
The standard four-by-185mm configuration is not the only possible arrangement because the S5 structure is modular.
Solidsteel offers custom height kits that allow the spacing between equipment levels to be adapted around different systems.
This can be particularly useful with the S5-5 because one tall amplifier may otherwise be the only component preventing the standard configuration from working.
Custom Spacing Can Transform the S5-5
If most of your components are relatively slim but one amplifier needs additional height, a customised arrangement may be preferable to abandoning the five-level format altogether. Speak to Audio T with your component dimensions before ordering if the standard 185mm intervals look restrictive.
S5-4 or S5-5?
S5-4
- 4 equipment levels
- Approximately 1010mm overall height
- 305mm / 205mm / 205mm standard clearances
- Approximately 37kg rack weight
- 55kg current load rating per level
- Much more accommodating of taller amplification
S5-5
- 5 equipment levels
- Approximately 1085mm overall height
- 185mm / 185mm / 185mm / 185mm standard clearances
- Approximately 47kg rack weight
- 55kg current load rating per level
- Greater component capacity for lower-profile equipment
When Is the S5-4 Better?
The Solidsteel S5-4 is likely to be the better choice where the system includes a substantial integrated or power amplifier.
Its 305mm largest standard interval is considerably more generous than any of the S5-5's four 185mm gaps.
When Does the S5-5 Make More Sense?
The S5-5 becomes more useful when five genuine equipment levels are required and most of the components are relatively conventional in height.
It can be especially effective with systems containing:
- Separate phono stages
- DACs
- Streaming transports
- CD transports
- Preamplifiers
- Headphone amplifiers
- External power supplies
Only 75mm Taller Than the S5-4
Despite adding an entire extra equipment level, the standard S5-5 is only around 75mm taller overall than the S5-4.
It achieves this by reducing the standard internal spaces to four equal 185mm intervals rather than retaining the S5-4's much taller 305mm amplifier section.
This neatly explains the trade-off between the two models: S5-5 prioritises component count, while S5-4 provides greater vertical flexibility.
S5-3, S5-4 or S5-5?
Fewer but Taller Components
The S5-3 and S5-4 provide a 305mm standard interval and are therefore generally easier to accommodate around large amplification.
More Lower-Profile Components
The S5-5 provides five equipment levels but uses four shorter 185mm standard intervals, making it particularly suited to systems with several conventional-height source and control components.
S5 Series or S3 Series?
S5 Series
- Two-level decoupled equipment platforms
- Secondary support surfaces
- Dedicated mechanical decoupling points
- StratoCell-damped aluminium supports
- 55kg current shelf rating
- Particularly relevant for mechanically sensitive equipment
S3 Series
- Conventional single-platform shelves
- Simpler equipment-support architecture
- StratoCell-damped aluminium supports
- 60kg current rack-shelf rating
- Excellent general-purpose hi-fi furniture
- More conventional shelf-spacing options
S5-5 or S3-5?
The Solidsteel S3-5 is the more conventional five-shelf alternative.
Its standard configuration also provides five levels, but uses conventional single-platform shelves and approximately 205mm equipment intervals rather than the S5's advanced two-level decoupled arrangement.
The S5-5 therefore places greater emphasis on mechanical decoupling, while the S3-5 offers slightly more standard vertical room and a slightly higher current rack-shelf load rating.
The Current S5 Range
The S5 Series is available in several standard configurations:
- S5-2: two levels with approximately 305mm clearance
- S5-3: three levels with approximately 305mm / 205mm clearances
- S5-4: four levels with approximately 305mm / 205mm / 205mm clearances
- S5-5: five levels with four approximately 185mm clearances
The right model is therefore determined by equipment height as much as the number of components in the system.
Black and White Finishes
The S5-5 is offered through Audio T in:
The equipment platforms use a polymer-laminate finish rather than genuine timber veneer.

How much usable equipment width does the S5-5 provide?
Approximately 500mm of usable width is available within the supporting structure, suitable for most conventional full-width hi-fi components.
Is the Solidsteel S5-5 good for turntables?
Yes. Solidsteel specifically recommends the S5 Series for turntable owners, and the open upper platform provides a natural position for a record player.
What is a decoupled hi-fi shelf?
A decoupled shelf separates the equipment-supporting surface from the main structural shelf through defined mechanical contact points, reducing the amount of direct mechanical coupling between the component and rack.
Does the Solidsteel S5-5 reduce vibration?
The S5-5 is designed to manage unwanted mechanical interaction through its decoupled equipment platforms, internally damped support tubes and defined floor-contact points. No rack can completely remove every source of vibration.
Does a hi-fi rack improve sound quality?
The audible effect depends on the equipment, room and floor. Turntables and other mechanically sensitive components can be particularly dependent on their supporting furniture. Stable positioning, ventilation and individual equipment support remain useful practical benefits regardless.
What is StratoCell damping?
StratoCell is the sound-absorbing material Solidsteel installs inside the aluminium support tubes to help control resonance within the rack structure.
Will a full-width amplifier fit on the S5-5?
Most conventional amplifiers around 430mm to 450mm wide should fit within the approximately 500mm usable width, but height, depth, weight, rear connections and ventilation must also be checked.
Can an integrated amplifier fit inside the Solidsteel S5-5?
Potentially, but the standard enclosed shelf intervals are only approximately 185mm high. Check the amplifier's total height and manufacturer-recommended ventilation clearance carefully.
Can a power amplifier be used on the Solidsteel S5-5?
Yes where its dimensions, weight and ventilation requirements are compatible. Large or hot-running power amplifiers may be better positioned on the open top or supported separately.
Can a Class A amplifier be used on the S5-5?
Potentially, although Class A amplifiers can run very warm. The open upper platform or a separate amplifier stand may be preferable where an enclosed 185mm interval cannot provide sufficient airflow.
Can a valve amplifier be used on the Solidsteel S5-5?
Yes where dimensions and weight permit, although the open top is generally the most appropriate position for valve amplifiers requiring unrestricted space above their valves and transformers.
Can the Solidsteel S5-5 shelf spacing be changed?
Yes. The S5 Series is modular and Solidsteel offers custom height kits so the standard shelf spacing can be adapted to different equipment requirements.
Can the Solidsteel S5 Series be expanded or reconfigured?
Yes. The S5 is a modular system available in two, three, four and five-level configurations, with separate customisation kits available for changing shelf spacing.
What is the difference between the Solidsteel S5-4 and S5-5?
The S5-4 has four levels with standard clearances of approximately 305mm, 205mm and 205mm. The S5-5 adds a fifth platform but uses four shorter 185mm intervals, making the S5-4 better suited to taller amplification and the S5-5 better suited to a larger number of lower-profile components.
Is the S5-5 much taller than the S5-4?
No. The S5-5 is approximately 1085mm high compared with around 1010mm for the S5-4, an increase of only about 75mm despite the additional equipment level.
What is the difference between the Solidsteel S5-5 and S3-5?
The S3-5 uses conventional single-platform shelves with approximately 205mm standard intervals, while the S5-5 uses advanced two-level decoupled equipment platforms with four approximately 185mm intervals. The S5 places greater emphasis on mechanical decoupling, while the S3 provides slightly more standard vertical clearance.
Is the Solidsteel S5-5 suitable for vinyl systems?
Yes. Its five equipment levels can accommodate a turntable, separate phono stage and several supporting analogue or digital components while retaining an individual platform for each.
