Product Description

The Sugden Audio Sapphire FBA-800 is a pure Class A stereo power amplifier which draws on Sugden's extensive experience with Class A amplification to offer immense resolution and soundstage, the kind which only a Class A design could offer. Comparatively, the FBA-800 offers substantial power, and is suitable with a wide range of loudspeakers.

As with all Sugden products, the FBA-800 is designed and manufactured by Sugden in West Yorkshire, and their use of through hole components (as opposed to surface-mount) enhances the life, performance and reliability of their products.

Sugden have utilised their extensive experience in Class A amplification with the FBA-800, and have certainly proven their belief that Class A offers sonic advantages. It is always exciting when a new project reaches the performance stage and Sugden state that the FBA-800 amplifier has continued to astound and excite through thousands of hours of tuning and development.

What Makes the FBA-800 special?

The FBA-800 Power Amplifier is a Stereo, Class A amplifier operating in the Bridged Mode with the Output earth Floating. Each channel consists of two amplifiers working as voltage amplifiers driving an output stage of Bridged Power transistors. The advantages are a low noise floor, better power output relative to the voltage rails (x2) and with the fixed current of the Class A mode, low output impedance and better load tolerance. The Amplifier has been designed for modern high efficiency loudspeakers.

The Power amplifier is D.C. coupled, with a servo lock, ensuring excellent low frequency detail. For safety purposes the amplifier includes a d.c. protection circuit. This circuit is statically switched using extremely low impedance Mosfet switching devices. This circuit also soft switches the Power Amp On and Off.

The power supply is a low impedance design with a single custom made bi-filar wound transformer, with four separate windings, The main smoothing capacitors for the output stage are specially developed for professional audio applications with excellent ripple characteristics and long life. The Four power transistors per channel in the output stages are multi emitter devices with an output capability of 26 amps per device.

The FBA-800 operates in the full balanced mode from the input of the unit to the output. This is accomplished by using the two amplifiers per channel in the balanced mode. For people who want to experience all the emotions of music this Amplifier is set completely in Class ‘A’. No compromise has been taken with the build quality of its electronic circuitry, electronic components, or case work. It includes gold-plated circuit boards, and high quality internal silver wiring all designed to give long life and the ultimate musical performance.
