cally induced distorted (MID)
has led to the elimination of
magnetizable materials wher-
ever 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, capaci-
tors in particular, are thus guar-
anteed a non-resonant environ-
ment.

The heavy, thick chassis offers a
vibration-proof environment
for the sensitive electronics
inside and provides crucial
shielding from a polluted world
of low and high-frequency
radio waves, power-line radia-
tion and other electrical inter-
ference. Meticulous attention to
such issues makes a significant
contribution to the relaxing,
open and transparent Gryphon
sound.

Unique, non-invasive protection
circuitry offers reliable, fuss-
free protection without compro-
mising signal purity and signal

path simplicity, with no conven-
tional relays in the signal path
to degrade or compress sound. 

The ground path has been care-
fully laid out in order to achieve
superior sonic performance
with no loss of stability.
Component layout has been
designed to ensure the shortest
conceivable signal path.

Exhaustive investigation under-
lies the selection of every com-
ponent part and many original,
proprietary components are
custom-built exclusively for
Gryphon. Because what is left
out is just as important as what
goes in, an absolute minimum
of internal wiring is included.

By lavishing attention on each
aspect of the circuit and fully
understanding the purpose and
behavior of every single part of
the whole, our designers can
optimize performance in each
section, before moving on to
the next step. This ensures sim-
plicity, a short signal path and a
unity of purpose with a single,
well-defined objective: musical
purity.

In the interest of ultimate fideli-
ty, tone controls, balance con-
trols and other unnecessary
components have been ban-
ished from the signal path.
