For over thirty years, the team at J.E. Sugden & Co. Ltd. have been applying their extensive knowledge and experience to the development and production of specialist audio amplifiers for the discerning music lover. Sugdens very first product was the revolutionary A21, the world's first commercial, solid state, Class-A amplifier. Designed developed and manufactured in the mid-1960s by James E. Sugden, the Company's founder. The Sugden company's belief in the benefits of Class-A technology to musical performance makes it a paramount consideration to product design. The original circuit of the A21 has been subjected to continuous improvement, a policy which has resulted in the A21A (right) after 30 years being the amplifier against which others are judged.
The Class-A technology, with its total avoidance of switching distortion, is present in all Sugdens current generation of products and will be found in forthcoming generations of Sugden products. Sugden products are hand crafted in West Yorkshire, England by a team of people who care for the presentation of their skills and the performance of their products. Sugdens - a special company that develops a long term association with its customers through the musical performance and long life of its products
