Brand Sugden

The A21SE Integrated Amplifier is a single ended solid-state pure class ‘A’ design. The pre-amplifier has a cascode input stage, current feedback with the input and output being in phase.  Other design points include high input impedance, high voltage gain in the first stage with low distortion, wide bandwidth, low noise and very low output  impedance.  Left and right line stages have current shunt power supplies from a dedicated transformer winding.  The input signals are relay switched reducing signal paths to a minimum. The A21SE is capable of producing music in its most natural and organic form.  Free from crossover distortion, power can be delivered smoothly without the high frequency ‘pain’ associated with so many transistor amplifiers.

Facilities:

Inputs – Five line level operated by relays.

Ouputs – Pre-out (variable), tape out (fixed), one pair of stereo multi-way binding posts and LTVS supply for A21SE Stage One Phono Amplifier.

Remote Control – Volume up/down.

Specifications:

Line Input sensitivity – 110mV for maximum output.

Power Output – 30 watts pure Class ‘A’ into 8 ohms both channels driven.  40 watts pure Class ‘A’ into 4 ohms both channels driven.

Frequency Response – 20Hz to 20kHz +/- 0.5dB.

Bandwidth – 12Hz to 141kHz +/- 3dB.

Signal to Noise – >84dB.

Packed Weight – 14 kgs.

Rescuing Music From Technology

When only the sound matters, the look is simply a bonus! Designed and hand made in England for your ultimate listening pleasure.

Sophisticated Audio Technology coupled with the Finest Craftsmanship

Sugden Audio products reflect the best in the company’s long history of producing amplifiers, digital processors and loudspeakers with exceptional musical qualities. A history which stretches over forty-five years to the first commercially available pure class ‘A’ solid state amplifiers. Amplifiers which are hailed as classics and which are sought after even to this day.

The Sugden signature sound gives you the rich bodied sound of valve amplifiers without the related problems.

The company continues to hand-build products with each individual unit being the responsibility of one technician. This may appear indulgent in an age of automation and mass production, but it can be justified by the quality standards, which are the payback of a satisfied workforce. Sugden production methods are the antithesis of robotic mass production and the maelstrom of that working environment. Which other company can cite live key assembly staff with the experience of over one hundred years of continuous combined service? Their pride and satisfaction in producing Sugden products lifts the standards of all the employees, they are the team leaders. For Sugden is a team of special people, demanding of their own standards, creating an added dimension for the discerning owners of Sugden products.

Sugden design and development, whilst encompassing and considering the latest technological developments, only include them if they improve the perceived sonic performance. Whilst the personal computer has brought tremendous opportunities for extending design criteria, circuit modelling, product modelling and layouts, Sugden products are not designed by computer but are the products of computer aided design. The design and development priorities of Sugden have always been focussed on the final ability of the equipment to reproduce a total musical performance. The development of Sugden Products has a major subjective element to it. Hours of prototyping, component selection, measuring and listening to enable Sugden Audio products to deliver a complete musical experience. This is the sophistication that is added to Sugden products after the design tools have been fully exhausted.

The materials used by Sugden are selected for their intrinsic contribution to the overall performance of the equipment. The overall screening properties of full metal cases form an essential clean environment for the sophisticated electronic circuit.
