Sugden A21SE Signature Integrated Amplifier

Sugden A21SE Signature Amplifier Delivers Pure Class A Performance

The Sugden A21SE Signature Integrated Amplifier is a refined evolution of the celebrated A21, optimised for audiophiles seeking an authentic, high-fidelity experience. Built on the classic Sugden philosophy of pure Class A single-ended operation, this special edition A21SE amplifies its predecessor's strengths with remarkable upgrades, including a significantly larger power supply and an advanced pre-amplifier stage. These enhancements elevate sound clarity, dynamics, and control for an even more immersive listening experience.

Enhanced Power Supply Boosts Dynamic Range and Detail

A fifty percent increase in power supply capacity ensures that the A21SE Signature delivers exceptional power and stability across a wide range of speakers. Operating at 30 watts per channel into 8 ohms (and 40 watts into 4 ohms), the amplifier produces not only higher output but also enhanced dynamic response. This power reserve allows it to maintain precise control even at low listening levels, with enriched micro-dynamics that reveal subtle tonal details and textures. With this setup, users can experience delicate nuances and expansive sound stages even at lower volumes, making it ideal for both intimate and energetic listening sessions.

Sophisticated Pre-Amplifier Stage Elevates Clarity

The A21SE Signature's advanced pre-amplifier stage refines audio fidelity, enabling crystal-clear highs and balanced mids without the harshness often associated with other high-powered systems. This stage is finely tuned to maximise clarity while retaining the warm, natural tonality Sugden amplifiers are known for. By minimising colouration and distortion, the pre-amplifier gives the music a transparent, yet rich sound profile. Even complex arrangements come through with superb separation and depth, making every listening session feel immersive and realistic.

Flexible Connectivity for Modern Audio Setups

Equipped with five line-level inputs operated by relay, the Sugden A21SE provides flexible connectivity to various audio sources, including CD players, DACs, and turntables with a phono stage. It also features one variable pre-out for seamless integration with external amplifiers or powered subwoofers, plus a tape-out option. The binding posts are multi-way and robust, accommodating high-quality speaker cables for secure connections. A remote control with RC5 handset compatibility further enhances usability, allowing for easy volume adjustments from anywhere in the room.
