Sugden A21 Signature (AL + Phono) Available in Graphite Only**

A21 Signature Line and Integrated Amplifier

The Sugden pure class A design provides affordable high-end performance from a beautifully engineered single box integrated amplifier.

Compact in size with a simple but stylish design, the A21 is possibly the only amplifier you will ever need. With many of the original A21’s still in daily use after fifty years, it could also last a life time. Providing a large soundstage and depth to all types of music, the A21 is an amplifier you can listen to for hours without fatigue.

The single ended voltage rail circuit provides impressive dynamics and incredible bass.

This line (pre) amplifier is a modern update of Sugdens classic A21 and A21a amplifiers that became a reference standard on many continents, further improved to offer enhanced performance and available in black or silver. Sugdens 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. 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 standard. Further improvements have achieved significant enhancement of performance and the amplifier has been rebranded as the Sugden A21a Series 2.


The A21 Signature integrated amplifier is available with or without a MM/MC phono input. Without a phono input it is designated the A21L (line input only). A21aL models can be fitted with a phono input at a later date.
