Audio T Verdict
The Solidsteel S3-B is the compact amplifier stand in the S3 family, giving substantial amplification a proper low-level support without occupying as much floor space as the deeper S3-A.
At approximately 404mm wide and 480mm deep, it is particularly well suited to more compact power amplifiers, integrated amplifiers, monoblocks and large power supplies. Solidsteel's current specification rates its dedicated S3 amplifier stands to support up to 120kg, so weight is unlikely to be the limiting factor for most domestic equipment.
The construction is more sophisticated than a simple equipment board. The 30mm MDF platform is supported by anodised aluminium components incorporating StratoCell damping material, while adjustable stainless-steel spikes allow the stand to be properly levelled and matching floor-protection discs are included.
If your amplifier comfortably fits the S3-B footprint, we would choose it over the larger S3-A simply because it takes up less room. If the amplifier is particularly deep, however, the S3-A's additional front-to-back space is likely to make installation and cable routing easier.
Check the Amplifier Feet Before Ordering
The S3-B platform measures approximately 404mm wide x 480mm deep. Many conventional hi-fi amplifiers are wider than 404mm at the chassis, so check the position of the equipment feet rather than chassis dimensions alone. All support feet must sit securely on the platform and the component must remain completely stable.
Solidsteel S3-B Compact Amplifier Stand
The Solidsteel S3-B is the smaller dedicated amplifier platform within the company's current S3 Series of specialist hi-fi furniture.
Designed and manufactured in Italy, it provides a stable low-level support for power amplifiers, integrated amplifiers, monoblocks and other substantial audio components that do not need the additional depth of the larger S3-A.
The compact 404 x 480mm platform is combined with damped aluminium supports, steel structural components and individually adjustable stainless-steel floor spikes.

Why Use a Dedicated Amplifier Stand?
A large amplifier can be one of the most demanding components to accommodate within a hi-fi system.
Amplifiers are often:
- Heavier than source components
- Connected to substantial mains and speaker cables
- Hotter running
- Fitted with large heatsinks
- Difficult to accommodate within normal shelf spacing
A dedicated low-level amplifier stand can therefore make practical sense even before considering vibration control.
Keep Heavy Amplification Close to the Floor
Positioning a substantial amplifier close to floor level can reduce the amount of weight carried high up in the main equipment rack.
It can also make a heavy component easier to install and provide more straightforward access to rear connections.
With a current dedicated-amplifier-stand capacity of up to 120kg, the S3-B has ample load capability for the vast majority of domestic amplifiers that physically fit its platform.
120kg Maximum Load
Solidsteel's current S3 specification rates its dedicated power-amplifier stands for loads of up to 120kg.
That is approximately 265lb.
This is substantially greater than the 60kg rating used for each shelf on the conventional multi-level S3 racks.
Weight Is Only One Part of the Equation
An amplifier can be well below the S3-B's load limit but still be unsuitable if its feet are too widely spaced or its chassis and rear connections require more room than the platform provides. Always check dimensions, foot placement, ventilation and cabling as well as weight.
Compact 404 x 480mm Footprint
The S3-B is deliberately smaller than the regular S3-A amplifier platform.
Its approximately 404mm width and 480mm depth make it particularly useful where:
- The amplifier itself is relatively compact
- The equipment feet sit comfortably inside the platform
- Floor space is limited
- The stand needs to sit relatively close to a wall
- The additional depth of the S3-A is unnecessary
If the equipment fits properly, there is little reason to use a larger platform simply for the sake of it.
Check the Width Carefully
The S3-B is approximately 404mm wide, while many conventional full-width hi-fi components measure somewhere around 430mm to 450mm across their chassis.
This does not necessarily rule them out because the support feet can sit well inside the outer edges of the case.
The important question is whether every foot is safely supported and the amplifier remains completely stable.
Do Not Balance Equipment Across the Platform
A small amount of chassis overhang may be harmless where the equipment feet remain properly supported, but an amplifier should never be used on the S3-B if any support foot sits beyond the platform or the component feels unstable.
480mm Platform Depth
The 480mm depth suits many conventional integrated and power amplifiers while keeping the stand relatively compact.
However, the amplifier's published chassis depth does not include everything attached behind it.
Allow Room for Rear Connections
Additional space may be needed for:
- IEC mains plugs
- Substantial mains cables
- XLR interconnects
- RCA interconnects
- Speaker binding posts
- Banana plugs
- Spade connectors
- Trigger and control cables
Check the Installed Depth
A 450mm-deep amplifier may require considerably more than 450mm once its rear cables are connected. Allow enough space for cables to leave their sockets naturally without tight bends or excessive pressure.
30mm MDF Equipment Platform
The S3-B uses a substantial 30mm MDF equipment platform.
Solidsteel's current S3 specification describes its platforms as ennobled MDF with a premium polymer-laminate finish.
The engineered MDF core provides a consistent structure, while the considerable thickness gives the platform useful rigidity beneath heavy equipment.
Anodised Aluminium Supports
The supporting components beneath the platform use anodised aluminium.
Aluminium provides the necessary rigidity while helping to keep the complete S3-B stand to a manageable weight of approximately 6kg.
Internal StratoCell Damping
Solidsteel fills the aluminium support sections internally with StratoCell sound-absorbing material.
The idea is to damp resonant behaviour within the metal structure rather than leaving the supports as completely hollow tubes.
This combines mechanical rigidity with internal damping instead of making the complete support soft or compliant.
What Is StratoCell?
StratoCell is the sound-absorbing damping material Solidsteel uses inside the aluminium support poles of the S3 Series. Its purpose is to help control resonant behaviour within the supporting structure.
Galvanised-Steel Frame and Fixings
Solidsteel's current S3 construction uses galvanised-steel components for the frame and fixing hardware, finished with durable powder coating.
The complete S3-B construction combines:
- 30mm MDF equipment platform
- Premium polymer laminate
- Anodised aluminium supports
- Internal StratoCell damping
- Galvanised-steel frame and fixing hardware
- Adjustable stainless-steel spikes
- Stainless-steel protective floor discs
- ABS protective interfaces
Adjustable Stainless-Steel Floor Spikes
The S3-B uses adjustable M8 stainless-steel spikes at floor level.
Each support point can be adjusted individually, allowing small irregularities in the floor to be compensated for and the equipment platform to be levelled accurately.
Why Levelling Matters
The first job of an amplifier stand is to provide a stable base.
A substantial amplifier should not rock or shift because one support point is not making proper contact with the floor.
Correct adjustment of the S3-B's spikes helps make sure the platform remains solid before the equipment is installed.
Stainless-Steel Protective Floor Discs
Solidsteel supplies stainless-steel S Series floor-protection discs with current S3 products.
These sit underneath the pointed spikes where direct metal contact could otherwise mark the floor.
Protect Timber and Hard Floors
Use the supplied protective discs on timber, laminate, tile, stone and other surfaces that could be marked by direct contact with a pointed spike. Position and level the stand before installing particularly heavy amplification wherever practical.
Improved Amplifier Ventilation
One of the strongest practical arguments for a dedicated amplifier platform is unrestricted space above the component.
Many power and integrated amplifiers generate substantial heat and rely on airflow through their chassis or heatsinks.
A low open stand can therefore make more sense than placing the amplifier beneath another equipment shelf.
Useful for Class A Amplifiers
Class A amplifiers can run particularly warm because their output stages remain heavily biased even when little or no music is being reproduced.
Where the amplifier fits the S3-B platform, the completely open space above it can provide a very practical installation.
Useful for Valve Amplifiers
Valve amplifiers can also benefit from unrestricted vertical space.
The S3-B can be used where the amplifier fits safely and remains within the load rating, although the equipment manufacturer's ventilation guidance should always take priority.
Always Follow the Amplifier Manufacturer's Ventilation Guidance
An open amplifier stand cannot compensate for being positioned underneath low furniture, close to curtains or in another location that restricts airflow. Maintain the clearances specified for your amplifier.
Suitable for Integrated Amplifiers
The S3-B is not restricted to separate power amplification.
A substantial integrated amplifier may also benefit from a dedicated stand where it is:
- Heavy
- Hot running
- Connected to thick speaker cables
- Better positioned separately from source equipment
- Taking up useful space in the main rack
Suitable for Monoblock Amplifiers
A pair of S3-B stands can provide individual platforms for left and right monoblock amplifiers.
Where the monoblocks are sufficiently compact, the smaller S3-B footprint can be particularly useful when placing an amplifier beside each loudspeaker.
This arrangement may also allow shorter speaker-cable runs depending on the system layout.
Suitable for Power Supplies and Other Heavy Components
The S3-B can also support other substantial hi-fi components where the dimensions are suitable.
Possible applications include:
- Large external power supplies
- Mains regenerators
- Power-conditioning components
- Heavy control electronics
The same rules apply: check the weight, footprint, feet, ventilation and cabling before installation.
Free a Shelf in the Main Equipment Rack
Putting the amplifier on a separate S3-B can leave the main rack available for more mechanically sensitive or frequently accessed components.
For example, a three-shelf rack could hold:
- Turntable
- Streamer or digital source
- Preamplifier
while the power amplifier sits separately at floor level.
Does an Amplifier Stand Reduce Vibration?
The S3-B is designed to provide a rigid, damped and accurately levelled mechanical support.
Its construction combines a substantial equipment platform with damped aluminium supports and defined floor-contact points.
The degree to which that produces an audible change will vary with the amplifier, floor construction, loudspeakers and wider system.
The Practical Benefits Matter Too
Even where a change in sound is subtle, a dedicated amplifier stand can still provide better stability, improved ventilation, easier cable routing and more useful space within the main equipment rack.

Which Solidsteel Amplifier Stand Should You Choose?
The choice between S3-A and S3-B should mainly be determined by the amplifier footprint rather than assuming the larger model is automatically better.
Choose the S3-B when the amplifier and all of its feet fit comfortably within the 404 x 480mm platform. Its smaller footprint makes for a tidier installation.
Choose the Solidsteel S3-A if the amplifier is wider, considerably deeper or requires more room for substantial rear connections.
Part of the Solidsteel S3 System
The S3-B shares its finishes and broad design language with Solidsteel's multi-level S3 equipment racks.
It can therefore be used alongside:
This allows heavy amplification to be positioned separately while retaining a consistent appearance across the complete system.
Black, White or Walnut
The S3-B is available in three standard finishes:
Black gives the most conventional hi-fi appearance, White suits lighter contemporary rooms and Walnut provides a warmer furniture-style finish.
Walnut Is a Laminate Finish
The S3 Walnut option is a wood-effect polymer laminate over the MDF platform rather than genuine timber veneer.
Made in Italy
Solidsteel has designed and manufactured specialist hi-fi, home cinema and professional audio furniture in Italy since 1990.
The S3-B remains part of the company's current Made in Italy S3 Series.

Yes. A pair of S3-B stands can provide individual platforms for left and right monoblock amplifiers, provided each amplifier fits the platform correctly.
Can I use the S3-B with an integrated amplifier?
Yes. Large or heavy integrated amplifiers can benefit from the same dedicated support, ventilation and cable access as separate power amplifiers.
Is the S3-B suitable for Class A amplifiers?
Yes where the equipment fits the platform safely. The completely open space above the amplifier can be useful for hot-running Class A designs, although the amplifier manufacturer's ventilation requirements should always be followed.
Can the S3-B be used with valve amplifiers?
Yes where dimensions and weight allow. A low open platform can be particularly useful with valve amplification because there is no shelf directly above the valves.
Does an amplifier stand improve ventilation?
It can. A low-level stand leaves the area above the amplifier completely open, which may provide better natural airflow than positioning the same component beneath another rack shelf.
Does an amplifier stand reduce vibration?
A specialist amplifier stand provides a stable and controlled mechanical support. The S3-B also uses damped aluminium supports and adjustable floor-contact points. Any audible effect will depend on the equipment, floor and wider system.
Does an amplifier stand improve sound quality?
The audible effect varies from system to system. More universal benefits include stable support, improved ventilation, easier cable management and separation from other equipment.
What is StratoCell damping?
StratoCell is the sound-absorbing material Solidsteel uses inside the S3 Series aluminium support sections to help control resonance within the structure.
Are the Solidsteel S3-B spikes adjustable?
Yes. The S3-B uses individually adjustable M8 stainless-steel spikes for accurate levelling.
Can the S3-B be used on wooden floors?
Yes. Solidsteel supplies stainless-steel protective floor discs that should be used beneath the spikes on timber, laminate and other surfaces that could be marked.
What is the difference between the Solidsteel S3-A and S3-B?
The S3-B is the smaller model at approximately 404 x 480mm, while the S3-A measures approximately 430 x 583mm. The S3-B takes up less floor space, while the S3-A provides more room for larger and deeper amplification.
