The Gryphon Master Tape Collection
In the Gryphon listening rooms, we have over the years had exclusive access to a unique library
of original master tapes of recordings made during the Golden Age of studio engineering from
1956-1976. Unlike conventional commercial LP releases, these master tapes capture the dynamic
contrasts and subtle inner harmonic structure of the musical event, forcing us to work to a higher
standard in our efforts to maintain the integrity of the original musical performance.
Design Principles
With state of the art technical equipment and some of the finest minds in the audio engineering field at
our disposal, the Gryphon brand continues to define the highest audiophile standards of subjective and
technical performance.
The dual mono configuration radically eliminates any possibility of crosstalk or other interference
between channels and provides infinite channel separation which contributes to the ability to create
space, focus, depth and transparency.
Because the electrical power coming out of your wall fluctuates wildly in terms of voltage and
distortion, Gryphon incorporates heavily regulated multi-stage power supplies that act as effective mains
conditioning filters. Displays and control circuits are fed by a separate power supply to isolate any digital
noise artefacts and effectively prevent them from contaminating the signal path.
While the printed circuit boards in more conventional audio products utilize conductor tracks a mere
35 µm thick, Gryphon employs at least 70 µm traces of the highest purity.
Beginning with our very first product, the Head Amp all Gryphon products have featured extremely
wide frequency bandwidth, because the ability to reproduce ultra-sonic frequencies with no difficulty
ensures linear phase across the audible frequency range.
The implementation of circuits with wideband frequency response is a painstaking endeavour in
which the actual layout and ground pattern of the circuit boards are crucial to the achievement of superior
sonic performance with no loss of inherent stability. Wideband frequency response ensures the high slew-
rate essential to the realistic handling of the ultra-fast transients which routinely occur in live music and is
crucial in recreating the natural decay of musical instruments.
Wide bandwidth also improves phase characteristics, for more correct sound-staging and imaging.
All Gryphon designs are realized with none or an absolute minimum of negative feedback, which when
present in large amounts can actually increase transient intermodulation distortion.
All Gryphon amplifiers are designed with zero negative global feedback except for the Gryphon
Antileon series of power amplifiers which have a minimum amount of negative global feedback for
improved linearity and bandwidth.
Gryphon research into the detrimental effects of magnetically induced distorted (MID) has led to the
elimination of magnetizable materials wherever possible. To eliminate the effects of stray magnetic fields,
non-magnetic materials are employed throughout, with the unavoidable exception of the transformer
shield box. The mechanical design of the cabinet and assembly methods are all carefully calculated to
ensure minimal resonance, either through the use of mechanically grounded high mass or decoupling.
Vibration-sensitive components, capacitors in particular, are thus guaranteed a non-resonant environment.
