Amplimo transformers for uncompromising audio performance

A high-quality amplifier starts with a high-quality power supply. That is why audiophiles, amplifier builders and professional manufacturers have relied on Amplimo toroidal transformers for decades. As the largest supplier of toroidal transformers in the Netherlands, Amplimo has built a strong reputation in high-end audio, professional audio and industrial applications.

Amplimo manufactures both standard and custom transformers and provides solutions for tube amplifiers, solid-state amplifiers, DACs, preamplifiers and professional audio equipment.

At SoundImports, you will find a comprehensive range of Amplimo toroidal transformers for new builds, restorations and upgrades of high-end audio equipment.

Why do audiophiles choose Amplimo?

Within high-end audio, the power supply is often considered the foundation of the entire amplifier. A stable and low-noise power supply contributes to lower noise levels, improved dynamics and optimal amplifier performance.

Amplimo transformers are known for:

- Extremely low magnetic stray fields

- High efficiency

- Silent operation

- High build quality

- European manufacturing and quality control

- Availability of standard and custom solutions

- Applications in high-end audio and professional audio equipment

Thanks to their toroidal design, these transformers generate less magnetic interference than traditional EI transformers, which is especially important in sensitive audio circuits.

What is a toroidal transformer?

A toroidal transformer uses a closed ring-shaped core around which the windings are wrapped. This design offers several advantages over traditional transformers:

- More compact dimensions

- Higher efficiency

- Lower electromagnetic radiation

- Less hum and vibration

- Higher power density

This is why toroidal transformers are widely used in high-quality amplifiers, DACs, power supplies and professional audio equipment.

When should you replace a transformer in an amplifier?

A power transformer often lasts for decades, but there are situations where replacement or upgrading is beneficial.

Restoration of vintage audio equipment

In classic amplifiers from brands such as Marantz, Leak, Dynaco, Quad, Luxman or DIY projects, an aging transformer can cause mechanical hum, heat generation or voltage-related issues.

Upgrading an existing amplifier

Many audio enthusiasts replace standard transformers with high-quality toroidal transformers to:

- Reduce hum

- Lower noise

- Increase current reserve

- Improve dynamics

- Enhance power supply reliability

DIY high-end audio projects

DIY amplifier builders often choose Amplimo because of the wide selection of secondary voltages, power ratings and configurations suitable for both solid-state and tube amplifier designs.

Does a new transformer improve sound quality?

A common question among audiophiles is whether a transformer actually affects sound quality.

Indirectly, the answer is yes.

The transformer determines the quality of the power supplied to the amplifier. A stable power supply with sufficient current reserve helps the amplifier perform better under load. This can improve dynamics, bass control and overall noise performance.

Within the audio community, linear power supplies with high-quality toroidal transformers are still highly valued for their simplicity, low noise and predictable performance.

Amplimo for tube amplifiers

Tube amplifiers place high demands on their power supplies.

Amplimo transformers are widely used in:

- Single-ended amplifiers

- Push-pull amplifiers

- EL34 amplifiers

- KT88 amplifiers

- 300B amplifiers

- 2A3 amplifiers

- Preamplifiers

The combination of stable voltages and low magnetic stray fields makes these transformers particularly suitable for sensitive tube circuits.

Practical applications of Amplimo transformers

Amplimo transformers are used daily in a wide range of commercial audio solutions.

High-End Hi-Fi Amplifiers

Many European amplifier manufacturers and DIY designers use Amplimo transformers as the foundation for high-quality integrated amplifiers, power amplifiers and preamplifiers.

Professional Audio Equipment

Amplimo also supplies transformers for professional audio applications, including studio equipment, signal processing systems and 100V line systems.

OEM Audio Manufacturing

Thanks to the possibility of producing custom transformers, Amplimo products are used by various OEM manufacturers developing high-quality audio equipment.

DIY Audio Projects

Within the international DIY audio community, Amplimo toroidal transformers have been among the most widely used power supply solutions for custom amplifiers and DIY audio equipment for many years.

Frequently Asked Questions About Amplimo Transformers

Are Amplimo transformers suitable for high-end audio?

Yes. Amplimo has developed dedicated product lines for high-end audio and has been supplying transformers for audiophile applications for many years.

What are the advantages of a toroidal transformer?

A toroidal transformer typically offers lower stray magnetic fields, higher efficiency and a more compact design than traditional EI transformers.
