Sugden Signature A21SE

A21 Signature Series SE Integrated Amplifier

Sugden's first commercial amplifier was the A21 in the mid-1960s. It is generally recognised as the first commercial, solid state Pure Class A amplifier to be available for audio enthusists. It was a very special amplifier with a single-ended Class A output configuration and current feedback. This design concept did not appear generally in commercial audio amplifiers until over a decade later. Capable of recreating a musical performance well in advance of its peers, it made the name of Sugden synonymous with musical performance. The true potential of the output configuration was realised in the 1980s when it was coupled to modern components, reduced internal filtering and multi emitter solid state output devices.

The result was an amplifier of extended and more controlled bass and treble but still retaining the wonderfully detailed mid range of the original design. The amplifier became the A21a, a reference amplifier on many continents. Further improvements have achieved significant enhancement of performance and the amplifier has been rebranded as the Sugden A21a Series 2.

The A21SE is a further expansion of the musical performance available from the Sugden single ended Class A output circuitry. Designed to provide more power output, greater speaker compatibility and a larger sound stage, it is not an uprated A21 Series 2 but a definitive amplifier in its own right.

The SE contains a pre-amp stage with high input impedance, high voltage gain, low noise, wide bandwidth, low distortion and low impedance to drive the Class A power stages. This pre-amp stage coupled to a fifty percent increase in the low impedance power supply enables a very dynamic sound stage to be developed with pin point imaging and fine tonal balance. An amplifier of unforced spontaneity which will satisfy the most discerning enthusiast with ‘simply more music’.

The A21SE is a line level input integrated amplifier without an integrated phono stage option. Sugden offer optional phono stages.
