Whether you're rediscovering old vinyl records or streaming modern audio, the A21 promises to envelop your room in warm, immersive sound.

Delivers Exceptional Dynamics and Bass

The A21 Signature amplifier is engineered with a single-ended voltage rail circuit, which creates an expansive soundstage with detailed imaging and depth. This design contributes to its remarkable ability to reproduce intricate dynamics, while the bass response is notably powerful and precise. This ensures a rich, balanced sound across all music genres—from delicate acoustics to hard-hitting electronic tracks. With an output of 25 watts per channel into 8 Ohms, it delivers ample power to drive a variety of loudspeakers, revealing musical nuances with an effortless ease.

Designed for Longevity and Enduring Performance

The A21 Signature embodies Sugden’s philosophy of building equipment that lasts. Its minimalist, durable construction ensures reliability, and many original A21 models from over 50 years ago are still in use today. The precision-engineered casing is both stylish and functional, providing a timeless design that looks great in any setting. This amplifier is built to withstand decades of regular use, ensuring you can enjoy its pure sound for a lifetime.

Flexible Inputs for Enhanced Connectivity

Featuring five line-level inputs (or four on models equipped with an optional phono input), the A21 provides versatile connectivity for all your sources, whether digital or analogue. Audiophiles with a love for vinyl can opt for the built-in MM/MC phono stage, making this an ideal amplifier for turntables. For those with a focus on line-level inputs, the A21L version omits the phono input, though it can be retrofitted later to suit your evolving needs.

Precision Volume Control with Remote Convenience

A remote-controlled volume system adds modern convenience to this classic amplifier, allowing for seamless control without sacrificing the quality of the listening experience. The volume adjustment is precise and smooth, ensuring accurate sound levels to suit any environment or listening session. Additionally, the inclusion of a pre-out (variable) and tape out (fixed) allows for integration with other high-fidelity systems, further expanding the flexibility of this integrated amplifier.

Built for the discerning audiophile, the Sugden A21 Signature delivers a wide frequency response of 10Hz–20kHz, with bandwidth extending from 6Hz to 200kHz, ensuring that every sonic detail is reproduced with clarity. The amplifier’s signal-to-noise ratio exceeds 83dB, providing a clean and quiet background, allowing the music to shine through without interference. Whether you're listening at low or high volumes, the sound remains detailed and transparent, with an absence of listening fatigue even during extended sessions.

The A21 Signature boasts a sleek, understated design that complements any home audio setup. With dimensions of 92 x 430 x 350mm, its compact size makes it a perfect fit for smaller spaces, while its robust build ensures longevity. The unit weighs 11kg when packed, making it manageable yet substantial enough to reassure users of its quality engineering.
