Sugden A21 Signature

Integrated amplifier

Sugden A21 Sig.

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.

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.

Brand

Sugden Audio

1981 - 2023 Under Tony Miller in 1981, production was relocated to their current factory in Heckmondwike, a short distance from where it all began. For 40 years Tony was the managing director of Sugden Audio until his passing in 2021. ​Patrick Miller began working at Sugdens in 1982 under the guidance of his father Tony. He worked in all areas of the business from assembly and packing through to sales and subsequently to leading their small but dedicated team. ​Patrick, Tony and the talented Sugden team have made it the brand it is known as today, with approximately 100 products being released between this time. ​Patrick Miller, Managing Director of Sugden Audio passed away in September 2023 following a short illness. A21 Pure Class A The A21 was the worlds’ first production pure class A transistor amplifier and a great success. The partnership with Richard Allan was short lived and within a year the amplifier was renamed the SUGDEN A21. Shortly afterwards, manufacturing was moved to larger premises in Cleckheaton, West Yorkshire Sugden A21 Present day Today they still manufacture in the same tradition with each Sugden product being handmade by a single highly skilled team member. Half of the team have been with the company for over thirty years enjoying a life-long career. Our involvement in the full manufacturing process still exists from design to despatch. We operate our own custom engineering shop , screen printing and assembly room. Sugden products are a truly handmade quality British product.​
