The
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 pre-amplifier 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
[not solid state] 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.
