Sugden Sapphire DAP-800 Digital Analogue Pre-Amplifier
Sugden Audio is pleased to introduce the new Sapphire DAP-800 High End Digital Pre-Amplifier & DAC which will further enhance the Company’s standing and reputation amongst discerning music lovers.
Sugden’s main objective in developing the DAP-800 has been musical performance coupled to a practical user interface, pride of possession and product longevity.
The market trends for new and fashionable technologies have not been ignored and the DAP-800 has been developed to complement and present the user with the very best euphonic experience.
As with all Sugden Products they are designed and manufactured by Sugden in its West Yorkshire, England premises. The use of through hole as opposed to surface mount components, where possible, enhances product life, performance and reliability.
The DAP-800 is an Analogue pre-amplifier with a separate in built DAC facility. It has:-
Analog Inputs:
One pair of Balanced Inputs.
Four Pair of Phono/RCA Inputs.
One Pair of By-Pass Inputs Phono/RCA.
Digital Inputs:
One x USB type B.
Two x Toslink Optical S/PDIF.
Three x Coaxial S/PDIF.
Analog Outputs:
One pair of XLR Balanced Outputs.
One pair of Phono/RCA Tape outputs.
Two pair of Phono/RCA outputs.
The individual sections of the pre-amplifier i.e. Analogue and Digital are self contained stages having their own Power Supplies voltage regulation and circuit board assemblies The analogue stage has a 50 watt toroidal transformer and the digital stage a 15 watt E core transformer. The digital facility power supplies are totally isolated from the analogue stage.
The Pre Amplifiers analogue stage incorporates a Sugden VCV circuit in its most developed advanced form. This circuit has a high impedance input section, current gain stage (without attenuation problems) which drives a folded cascode stage into a Class ‘A’ output stage. The folded cascode circuit facilitates a wide bandwidth with maximum dynamics and low capacitive connectivity.
The tonal balance is irrespective of the output level and the sense of headroom, imaging and soundstage is to be believed.
The DAC facility to interface with digital products includes inputs for USB, Optical and coaxial S/PDIF signals. The actual DAC is a non-oversampling, digital filtering- less, DAC where the digital interface transceiver is a Wolfson Micro electronics device. The DAC also includes Post Conversion Filtering in the analogue output stage. The USB signal received is converted via a circuit including a Texas Instruments Universal IC whose SPDIF output signal is re-clocked and de jittered by the Wolfson interface transceiver.
This DAC configuration has been adopted for Sugdens Digital Processing after many many hours of actual auditioning of a wide sample of DSPs. The auditory perception/Musical performance in terms of dynamic balance, tonal balance, voice and emotion, are so much more satisfying and Sugden’s preference.
Facilities:
Analogue inputs – Four line level inputs, one balanced input & bypass.
Digital inputs – Three S/PDIF coax, two S/PDIF optical & one USB type B Word length up to 24bit 96k.
Outputs – Two line level outputs, one balanced output, & tape output.
Volume control – Motorised remote control (analogue) RC5 compatible.
Mains power switching – Separate for analogue and digital circuits.
Technical Specifications:
Input sensitivity – 120mV for 1 Volt out.
Maximum output – 9 Volts.
Frequency response – 0dB 15Hz – 98kHz. 3dB 8Hz – 125khz.
Signal to noise – >85dB.
Distortion – <0.05% @ 1kHz, 1Volt out.
Nett Weight – 10 kgs.
Dimensions – 120 x 430 x 340mm (HWD).

Sugden Sapphire FBA-800 Floating Bridge Pure Class 'A' Stereo Power Amplifier
Sugden Audio is pleased to introduce the new Sapphire FBA-800 Pure Class ‘A’ Stereo Power Amplifier which will further enhance Sugden’s standing and reputation amongst discerning music lovers.
Sugden’s main objective in developing the FBA-800 has been musical performance coupled to a practical user interface, pride of possession and product longevity.
The market trends for new and fashionable technologies have not been ignored and the FBA-800 has been developed to complement and present the user with the very best euphonic experience.
As with all Sugden Products they are designed and manufactured by Sugden in its West Yorkshire, England premises. The use of through hole as opposed to surface mount components, where possible, enhances product life, performance and reliability.
Sugden has extensive experience in Class ‘A’ amplification and overwhelming belief in the sonic advantages of Class ‘A’ operation.
The FBA-800 is a, Floating Bridge Power Amplifier operating in Pure Class ‘A’ output mode. Power output is set at 40 watts / channel, the unit’s toroidal transformer is rated at 350va. The Amplifier has the input facilities of: Balanced Input or Phono/asymmetric input, (both stereo pairs) Output is through a Stereo pair of Speaker Binding Posts.
Selected optional facilities are:
Input sensitivity: this can be reduced in one step by -6dB. This allows the user to adjust the balance/ matching of the Audio, chain, i.e. PreAmp – Power Amp,- Loudspeakers. The sensitivity is selected by Push Button, located on the front Panel.
Balanced or Phono/RCA input: is also exercised by a Push Button on the front Panel.
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.
It is always exciting when a new project reaches the performance stage and the FBA 800 amplifier through its development has continued to astound and excite through thousands of hours of tuning and development. The finished product is a precious link to Simply More Music.
Facilities:
Inputs – Stereo line level, stereo balanced.
Outputs – Stereo pair multi way locking binding posts.
Front panel gain selector – 6dB input attenuation.
Front Panel input selector – RCA or XLR.
Specifications:
Input sensitivity – 735mV for full output.
Power output – 40 Watts into 8 ohms both channels working.
Frequency response – 0dB 20Hz – 80kHz.
Bandwidth – 3dB points 6Hz – 113kHz.
Signal to noise – >96dB.
Distortion at 1 Watt,1 kHz – >0.05%.
Net weight – 25kgs.
Dimensions – 206 x 430 x 460mm (HWD).
