The Sugden A21SE Signature is a high-end stereo integrated amplifier built around Sugden’s distinctive pure Class A single-ended voltage-rail topology. Developed as a special edition of the classic A21SE, the Signature version combines the character of Sugden’s established Class A design with an upgraded power supply and refined pre-amplifier stage.

The A21SE Signature features a 50% larger power supply than the classic A21 design, providing increased power reserves, improved dynamics and greater control over a wider range of loudspeakers. Its sophisticated pre-amplifier stage is engineered for greater clarity and detailed high-frequency reproduction without introducing excessive brightness.

With 30 watts per channel into 8 ohms and 40 watts per channel into 4 ohms, the amplifier provides excellent control and musical expression while maintaining the smooth, natural presentation associated with Sugden Class A amplification.

The amplifier includes five relay-operated line-level inputs, a variable pre-out, fixed tape output and stereo multi-way speaker binding posts. A motorised volume control can be operated using the supplied RC5-compatible remote handset, providing convenient adjustment from the listening position.

The A21SE Signature also offers an exceptionally wide 12Hz–141kHz ±1dB frequency response, 6Hz–280kHz bandwidth and a signal-to-noise ratio above 90dB, making it an excellent choice for a refined, high-resolution two-channel hi-fi system.
