Sugden Say….
Sugden HeadMaster is a dedicated Headphone Amplifier with exceptional qualities of musical performance. It has been specially developed to extend the boundaries of audio pleasure into the ultimate near-field listening conditions. It is suitable for use with most commercial headphones.
The unit is equipped with three stereo input facilities, a parallel tape output, and a switched pre amplifier output. These facilities create a very flexible piece of equipment, which can operate as a stand alone dedicated headphone system or be combined as a high quality pre-amp in a total Audio system. The special design features of the amplifier circuitry have been incorporated to enhance headphone performance but also facilitate a very high quality preamplifier performance.
The amplifier configuration is pure Class A constructed completely from discreet components. The application of the Class A circuit has been optimised to obtain its characteristic benefits of superb low level listening and low distortion. Particularly important to the use of headphones is the inherent avoidance with the Class A configuration of odd and high order harmonic distortion. The amplifier is wide bandwidth with a very neutral and transparent sound stage through the full musical spectrum and volume range. The inputs of the amplifier are selected through a logic operated relay circuit to keep the input signal paths as short as possible. The relays used are twin gold contact bifurcated crossbar types with a contact resistance of less than 0.05 ohms. These relays, which are used in all Sugden Hi-End pre amps, are chosen for their non-invasive handling of the incoming signals. The single ended phono connectors are all high quality individual, gold plated connectors with Teflon inserts.
The housing for the electronics is creatively designed and precision engineered from high quality aluminium in our own manufacturing facility. The sculptured presentation as well as advancing pride of possession includes full practical and ergonomic considerations. Its mass is particularly relevant to headphone use and superb Audio performance.
Together with all Sugden products the acoustic qualities are enhanced by many hours of listening and component testing with the most sonically compatible selected for use. By not compromising on quality and continuity of production by our own skilled workforce we guarantee years of musical pleasure.
