Audio T Verdict
The Solidsteel HY-A is a dedicated low-level stand for substantial amplifiers and other audio electronics that are better supported independently from the main equipment rack. Its 600mm depth is the key difference from the smaller HY-B, giving deep power amplifiers considerably more room while keeping the overall width to a compact 404mm.
The construction is suitably substantial too. A 30mm lacquered MDF equipment platform sits on Solidsteel's four-pillar Hyperspike structure, with a full stainless-steel frame, rubber O-rings, adjustable floor spikes and matching protective discs.
At approximately 130mm high, the HY-A keeps heavy electronics close to the floor while raising the equipment platform approximately 100mm clear of it. With no shelf above the amplifier, ventilation is completely unrestricted vertically, which can be particularly useful with hot-running Class A, valve and high-power designs.
The current 70kg load capacity is more than sufficient for many serious amplifiers. The main compatibility checks are therefore physical size, foot placement, ventilation and the additional depth needed behind the chassis for mains, signal and speaker cables.
Check the Amplifier Feet and Rear Connections
The HY-A measures approximately 404 x 600mm across its equipment footprint. Check where the amplifier's feet or outriggers are positioned as well as its chassis dimensions, and remember that rear cables can add significant installed depth.
Solidsteel HY-A Power Amplifier Stand
The Solidsteel HY-A is the Regular amplifier stand in the current HY Series, designed to provide substantial power amplifiers, integrated amplifiers and other compatible audio or AV components with their own dedicated low-level support.
Its particularly generous 600mm depth makes it well suited to amplifiers that are difficult to accommodate inside conventional hi-fi furniture, while the open architecture provides unrestricted access for ventilation and cabling.

Why Use a Dedicated Amplifier Stand?
Large amplifiers can be awkward components to accommodate in a conventional equipment rack.
They are often:
- Heavy
- Deep
- Hot running
- Fitted with substantial heatsinks
- Connected to large mains and speaker cables
- Difficult to lift onto a high equipment shelf
A dedicated low-level platform gives the amplifier its own support without forcing it into a rack space that may compromise accessibility or ventilation.
600mm Depth for Large Amplifiers
The defining feature of the HY-A is its approximately 600mm front-to-back depth.
That is considerably deeper than most conventional hi-fi rack shelves and makes the HY-A particularly useful for substantial power amplifiers whose chassis, feet or rear connections require more room.
Why Is Amplifier Depth Important?
Many large amplifiers extend well beyond the dimensions of a conventional source component. Even when the chassis fits on a shelf, rear speaker terminals, mains plugs and interconnects can require significant additional room. The HY-A provides a much deeper supporting area than a conventional rack shelf.
404mm Width
The HY-A is approximately 404mm wide.
That may be narrower than the visible front panel of some conventional hi-fi amplifiers, but the important measurement is the location of the amplifier's supporting feet.
A chassis can overhang the platform slightly where all factory-designed feet remain safely supported and the finished installation is stable.
Do Not Assume a 430mm-Wide Amplifier Will Not Fit
Many conventional hi-fi amplifiers have a chassis wider than 404mm but use feet positioned well inside the cabinet edges. Measure the actual foot spacing before ruling the HY-A in or out.
Check the Complete Equipment Footprint
For any large amplifier, check:
- Chassis width
- Chassis depth
- Front and rear foot positions
- Any outriggers
- Oversized isolation feet
- Rear connectors
- Cable bend radius
- Total equipment weight
All manufacturer-designed support points should sit securely on the platform.
130mm Overall Height
The HY-A stands approximately 130mm high overall.
This deliberately low format keeps a heavy amplifier relatively close to the floor rather than raising its centre of gravity unnecessarily.
It also means less lifting is required when positioning equipment that may weigh several tens of kilograms.
Approximately 100mm Floor Clearance
Solidsteel specifies approximately 100mm of clearance between the floor and the underside of the HY-A equipment platform.
This raises the component away from the bare floor or carpet while retaining the deliberately low overall profile of a dedicated amplifier stand.
Excellent Ventilation
The HY-A places no shelf immediately above the amplifier.
This provides unrestricted vertical space for equipment using:
- Top-panel ventilation slots
- Natural convection cooling
- Large side-mounted heatsinks
- Valve or tube assemblies
There is also no enclosed side or rear structure to trap heat around the chassis.
Always Follow the Amplifier Manufacturer's Ventilation Guidance
An open stand provides plenty of physical freedom around the amplifier, but it does not override the manufacturer's cooling requirements. Maintain the recommended distances from walls, curtains, cabinets and other equipment.
Suitable for Class A Amplifiers
Class A amplifiers can produce substantial heat even when their physical dimensions appear relatively conventional.
The HY-A's completely open upper space makes it a useful choice for compatible Class A designs where an enclosed rack shelf would leave inadequate cooling room.
The amplifier must still fit safely within the platform and remain within the current 70kg load rating.
Suitable for Valve Amplifiers
The same open construction can work well with compatible valve amplifiers.
With no shelf directly above the equipment, valves and transformers have unrestricted vertical space, which can make the HY-A considerably more practical than placing a valve amplifier inside a conventional rack interval.
Useful for Stereo Power Amplifiers
The HY-A is particularly well suited to substantial stereo power amplifiers.
Keeping the power amplifier on its own low platform can also free valuable space in the main rack for source and control electronics.
Its generous depth is especially useful where the power amplifier has large rear binding posts and substantial mains connections.
Ideal for Monoblock Amplifiers
A pair of HY-A stands can be used beneath compatible monoblock amplifiers.
This allows each amplifier to have its own dedicated support and can make it possible to position the monoblocks closer to the loudspeakers, depending on the system layout.
HY-A for Monoblocks
The HY-A is particularly useful for long or deep monoblock designs. If the amplifier is relatively compact front-to-back, the smaller HY-B may achieve the same result while taking up less floor space.
Can an Integrated Amplifier Use the HY-A?
Yes. There is no requirement for the component to be a separate power amplifier.
A large integrated amplifier can make just as much sense on a dedicated stand where it is particularly heavy, deep or hot-running.
The HY-A can also be useful where moving the amplifier out of the main rack creates more suitable space for a turntable, streamer, CD player or other source components.
Can It Support an External Power Supply?
Yes. Large outboard power supplies can also be used where their dimensions and weight are compatible with the stand.
This can be useful with high-end systems where a power supply is similar in size and weight to the main amplifier itself.
70kg Current Maximum Load
Solidsteel currently specifies a maximum equipment load of 70kg for the HY Series.
That is approximately 155lb.
This comfortably covers many substantial integrated amplifiers, stereo power amplifiers and monoblocks.
Use the Current 70kg Specification
Older HY-A literature may quote a 120kg maximum load. Solidsteel's current HY Series specification now gives 70kg per equipment platform, so 70kg is the appropriate figure to use for new installations.
Weight Is Not the Only Compatibility Check
A 40kg amplifier may sit comfortably below the HY-A's load rating but still be unsuitable if its support feet do not fit safely on the platform.
Likewise, a physically compatible amplifier may require more space behind the stand than expected once speaker and mains cables are connected.
Dimensions, weight, support-foot spacing, ventilation and cabling should therefore always be checked together.
Approximately 8kg Stand Weight
The established HY-A specification gives an approximate unladen weight of 8kg.
Once a substantial power amplifier is installed, the complete assembly may become difficult to reposition.
Choose the stand location, route the cables and set the floor contacts before loading particularly heavy equipment wherever practical.
30mm MDF Equipment Platform
The HY Series uses a substantial 30mm MDF equipment platform.
MDF provides a consistent engineered structure without the continuous natural grain found in solid timber.
The HY platform uses a lacquered Black finish rather than a polymer laminate or genuine wood veneer.
Black Lacquered Finish
The current HY Series is available in Black.
The understated lacquered platform contrasts with the exposed stainless-steel structure and works naturally with both black and silver electronics.
Full Stainless-Steel INOX Structure
The HY Series uses stainless steel throughout its principal supporting hardware.
Current Solidsteel construction includes stainless steel for:
- The 39mm main frame
- Upper terminations
- Lower terminations
- Structural screws
- Adjustable floor spikes
- Protective floor discs
This gives the HY a fundamentally different construction from Solidsteel's aluminium-upright S Series amplifier stands.
Four-Pillar Construction
Four stainless-steel structural elements support the equipment platform.
The layout provides a rigid open frame without adding side or rear panels around the amplifier.
This helps keep cooling, cabling and equipment access straightforward.
Solidsteel Hyperspike Architecture
The HY Series is the four-pillar development of Solidsteel's established Hyperspike equipment-support concept.
The structure uses rigid metal components and defined mechanical interfaces rather than broad conventional furniture joints.
Rubber O-rings are also incorporated at selected points within the structure.
What Is Hyperspike?
Hyperspike is Solidsteel's specialist equipment-support architecture using rigid metal structures, carefully defined mechanical interfaces and adjustable pointed floor contacts. Its practical purpose is to provide audio and AV components with a stable and accurately levelled foundation.
Rubber O-Ring Interfaces
Rubber O-rings are positioned at selected interfaces within the HY structure.
The compliant material creates a different mechanical connection from simply joining every part through broad rigid metal-to-metal contact.
This forms part of Solidsteel's overall approach to mechanical support within the HY range.
Does an Amplifier Stand Improve Sound Quality?
The audible effect of changing equipment support depends on the component, floor, room and support being replaced.
Rather than promising a fixed sonic improvement, the HY-A provides several clear practical and mechanical benefits:
- Dedicated support for the amplifier
- Accurate levelling
- Unrestricted vertical ventilation
- Easy rear cable access
- Separation from general household furniture
- Defined mechanical interfaces
- Reduced need to place heavy amplification high in a rack
Any audible difference should be judged within the context of the complete system.
Adjustable Stainless-Steel Floor Spikes
The HY-A uses individually adjustable stainless-steel spikes at floor level.
This allows small variations in the underlying surface to be compensated for so the platform can sit securely and level.
Accurate adjustment is particularly worthwhile when a very heavy amplifier is being installed.
Stainless-Steel Floor Protectors Included
Matching protective floor discs are supplied for use beneath the pointed spikes.
They should be used on vulnerable surfaces including:
- Wooden flooring
- Laminate
- Tile
- Stone
- Other finished hard floors
Protect Hard Flooring
A heavy amplifier can place considerable pressure through the stand's floor contacts. Use the supplied protective discs on vulnerable flooring and make sure the stand is correctly positioned before fully loading it.
HY-A or HY-B?
HY-A
- Regular amplifier stand
- Approximately 404mm wide
- Approximately 600mm deep
- Approximately 130mm high
- Approximately 100mm floor clearance
- 70kg current load rating
- Best for particularly deep amplifiers
HY-B
- Small amplifier stand
- Approximately 404mm wide
- Approximately 480mm deep
- Approximately 130mm high
- Approximately 100mm floor clearance
- 70kg current load rating
- More compact where additional depth is unnecessary
Which One Should You Choose?
The Solidsteel HY-B is approximately 120mm shallower than the HY-A.
If the amplifier's support feet and rear connections fit comfortably within the smaller platform, the HY-B saves useful floor space.
The HY-A is the stronger choice for deeper amplifiers or where generous front-to-back room is a priority.
HY-A or HY-C?
HY-A
- Regular amplifier stand
- Approximately 404 x 600mm footprint
- Long, relatively narrow platform
- 70kg current load rating
- Excellent for deep conventional-width amplifiers
HY-C
- Large amplifier stand
- Approximately 600 x 500mm footprint
- Much wider supporting area
- 70kg current load rating
- Better for unusually wide amplifiers and compatible subwoofers
The Solidsteel HY-C is wider but slightly shallower than the HY-A.
Choose between them according to the actual equipment footprint rather than assuming the physically larger-looking stand is automatically the better fit.
HY-A or S3-A?
HY-A
- Full stainless-steel Hyperspike structure
- Approximately 404 x 600mm footprint
- 30mm lacquered MDF platform
- 70kg current load rating
- Black finish
- Greater platform depth
S3-A
- Damped aluminium S Series structure
- Approximately 430 x 583mm footprint
- 30mm polymer-laminated MDF platform
- 120kg current load rating
- Black, White and Walnut finishes
- Higher current manufacturer load capacity
The Solidsteel S3-A actually carries more weight under Solidsteel's current specification, so the HY-A should not be thought of simply as the heavier-duty option.
The HY-A's distinction is its full stainless-steel Hyperspike architecture and particularly generous 600mm platform depth.
HY-A or HF-A?
HY-A
- Approximately 404 x 600mm footprint
- Approximately 130mm overall height
- Approximately 100mm floor clearance
- 70kg current load rating
- Black lacquered MDF platform
HF-A
- Approximately 404 x 600mm footprint
- Approximately 175mm overall height
- Approximately 135mm floor clearance
- 80kg current load rating
- Flat Black, Gloss Black and Gloss White finishes
The Solidsteel HF-A uses a very similar equipment footprint but raises the amplifier higher from the floor, offers additional finishes and carries a higher current load rating.
The HY-A is the lower-profile choice where approximately 100mm of floor clearance is sufficient.

Is the Solidsteel HY-A suitable for a power amplifier?
Yes. Solidsteel specifically classifies the HY-A as its Regular amplifier stand within the current HY Series.
Can an integrated amplifier be used on the HY-A?
Yes, provided its weight remains below 70kg and all of its supporting feet fit safely on the platform.
Can a Class A amplifier be used on the Solidsteel HY-A?
Yes where its dimensions and weight are compatible. The open-top format can be particularly useful for Class A equipment because there is no shelf immediately above the amplifier to restrict vertical airflow.
Can a valve amplifier be used on the HY-A?
Yes where the amplifier fits safely and remains within the load limit. The unrestricted vertical space above the platform can be especially useful for valve equipment.
Can the Solidsteel HY-A be used with monoblock amplifiers?
Yes. A separate HY-A can be used beneath each compatible monoblock, particularly where the amplifiers have deep chassis or substantial rear connections.
Will a 430mm-wide amplifier fit on the HY-A?
Potentially. The platform is approximately 404mm wide, but many amplifiers position their supporting feet inside the outer cabinet edges. Check the actual spacing of the feet rather than chassis width alone.
Can an amplifier overhang the HY-A?
A small amount of chassis overhang can be acceptable where every manufacturer-designed support foot remains securely on the platform and the equipment is completely stable.
Is the HY-A suitable for deep amplifiers?
Yes. Its approximately 600mm depth is one of its main advantages and makes it particularly suitable for deeper amplification that is difficult to accommodate on conventional hi-fi furniture.
How much space should I allow behind the HY-A?
Allow enough additional room for mains, signal and speaker connections. Large plugs, binding posts and heavy cables can add considerable effective depth beyond the amplifier chassis.
