Introduction
Welcome to the global
family of proud owners of
fine audio components
from Gryphon Audio
Designs of Denmark. Your
new Gryphon unit has
been painstakingly
designed to re-create the
sound of live music taking
place in its original
recorded space. Every
Gryphon product is
designed to cater
to the needs of the
most discerning
music enthusiast
with sumptuous
styling and superb userfriendliness which elevate
it above the mundane
world of conventional
audio components.
As audiophiles, the members of the Gryphon
design team are constantly reminded to keep their
priorities straight. We are
not involved in “hi-fi” for
its own sake, but strictly as
a means to an end, in the
service of our life-long
love of the live music
experience in all its sonic
and emotional glory.
Our higher goal is to
bring to the listener a
“You-Are-There” sensation. In taking up this challenge, the Gryphon
designers go back to
basics to analyze the
essential nature of the live
music experience. For us,
an awareness of
soundstaging, ambience and concert
hall dimensions are
necessary components. Dynamics and an
unambiguous sense of
instrument location even
in the loudest passages
are also high priorities. To
achieve these objectives,
Gryphon products offer
exceptional speed and
agility along with seamless coherence in the time
domain.
Since 1985, Gryphon
Audio Designs has quietly
gone about the business
3
of creating fine home
audio components. We
know that you will appreciate and enjoy the benefits of our accumulated
experience and share our
abiding passion for music.
The Gryphon
In Greek mythology: A
fabled creature, half-lion
and half-eagle, combining
the power of the “King of
Beasts” with the grace of
the “King of Birds”. The
guardian of the source of
gold and protector of the
Dionysian cup of infinite
wealth.
In the real world: An
acclaimed Danish audio
engineering company
employing cutting edge
technology and common
sense in the pursuit of the
purest musical experience. We feel that the
gryphon is an appropriate
symbol for our high sonic
goals.
The Man
Gryphon Audio Designs is
the brainchild of
Flemming E. Rasmussen
and the fulfillment of a
lifelong dream to allow
the purest essence of the
live music experience to
be recreated in the home
environment.
Rasmussen holds a
degree in painting and
graphic arts from the
Aarhus Art Academy,
Denmark. During his studies, Rasmussen developed
close relationships with
the local music community and designed many LP
covers and concert
posters. After graduation,
he taught photography
and painting and
designed textiles, before
founding 2R Marketing,
which quickly became
Denmark’s leading High
End audio import company.
Gryphon Audio Designs
was founded in 1985 as an
offshoot of 2R Marketing,
The first product, the now
The Gryphon Head Amp 1985

Flemming E. Rasmussen painting 1967
legendary Gryphon Head
Amp, grew from a one-off
spare time project developed only for the designers’ own home systems.
Although the Gryphon
project was initially strictly a hobby, not an actively
pursued commercial venture, demand generated
by reviews and word-ofmouth led to the formal
establishment of Gryphon
Audio Designs as a separate corporate entity.
Following the immediate
success of the Gryphon
brand, all import business
was phased out in 1993, so
that Rasmussen could
dedicate his efforts entirely to Gryphon.
Made In Denmark
Every product from
Gryphon Audio Designs is
designed and built in
Denmark. This is much
more than just a geographical fact. It is also a
seal of approval, a stamp
of quality. Living in a
region with no natural
resources (no oil, coal,
precious metals, etc.), the
Danes have learned to
rely on their quick wits
and skilled hands.
Innovative technology,
beautiful craftsmanship,
pride in one’s craft and a
keen eye for attractive
design are some of the
long-standing Danish traditions which are distilled
to their finest essence in
every unit that bears the
Gryphon name.
Musical Objectives
While scientific method
and sophisticated technology play an important
role in our electronics
design work, at Gryphon
we never lose sight of the
fact that the keen ears of
an experienced listener
are the most crucial “calibration tools.” Therefore,
every Gryphon product
exists for one simple purpose: to bring the user
closer in the never-ending
quest for a more natural
and convincing musical
illusion.
Gryphon is located in beautiful tranquil
surroundings.
5
every Gryphon design
has been built to cruise
effortlessly through even
the most demanding
musical passages, regardless of volume level, with a
musical presentation
defined by supreme articulation and immediacy,
subtle dynamic shading
and razor-sharp focus.
Refinement and delicacy
are combined with power
and authority for a natural,
involving listening experience.
The Gryphon Master
Tape Collection
In the Gryphon listening
rooms, we are fortunate to
possess a unique library
of more than 1,000 original master tapes of
recordings made during
the Golden Age of studio
engineering from 1956-
1976.
Unlike conventional commercial releases, our 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 name 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
6
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 artifacts
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 um thick,
Gryphon employs at least
70 um 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 ultrasonic frequencies with no
difficulty ensures linear
phase across the audible
frequency range.
distortion. All Gryphon
preamplifiers are
designed with zero, or
extremely low, negative
feedback. Gryphon power
amplifiers apply negative
feedback judiciously 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.
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
radiation and other electrical interference.
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 compromising signal purity and signal path simplicity, with no
conventional relays in the
signal path to degrade or
compress sound.
The ground path has been
The implementation of
circuits with wideband
frequency response is a
painstaking endeavor in
which the actual layout
and ground pattern of the
PC 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 soundstaging and
imaging.
All Gryphon designs are
realized with an absolute
minimum of negative
feedback, which when
present in large amounts
can actually increase TIM

carefully 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
underlies the selection of
every component 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 simplicity, a
short signal path and a
unity of purpose with a
single,well-defined
objective: musical purity.
In the interest of ultimate
fidelity, tone controls, balance controls and other
unnecessary components
have been banished from
the signal path.
Exterior Design
From the very beginning,
every Gryphon product
has offered stunning
audio performance,
sumptuous styling and
superb user-friendliness,
catering to the needs of
the discerning audiophile
who demands musicality,
convenience and aesthetics, all without compromise.
In every Gryphon product, form follows function
in a unique synthesis of
aesthetics and practicality. Gryphon stands for
sophisticated technology
with a high standard of
industrial finish that also
incorporates the best of
handcraftsmanship.
The peerless finish, build
quality, ergonomics and
pride of ownership that
contribute to the totality of
the Gryphon concept can
only be fully understood
and appreciated up close
and in person.
Rasmussen’s background
in fine arts and industrial
design gives every
Gryphon product a distinctive, luxuriant finish
which arises organically
out of the audio circuit
design and the user interface for a truly unique
integration of form and
function.
Manufacture and
Assembly
At our laboratories and
manufacturing facilities in
Denmark, we maintain full
control over every aspect
of development and production, and the members
of our conscientious staff
diligently follow each
Gryphon model from initial concept to early prototype, through to final quality control.
Printed circuit boards are
assembled by a supplier
of precision military and
medical equipment with
strict standards of quality
control and pre-inspection of components.
Chassis parts are manufactured by a specialist
chosen solely for the outstanding quality of workmanship. In every aspect
of every Gryphon product, the same stringent
standards of excellence
apply.
Following a 48-hour burnin, each product is tested
again, before being subjected to Gryphon’s custom-developed transport
simulator which simulates
the inevitable shaking that
a product will encounter
in transit.
Correct AC polarity contributes greatly to optimum performance. If you
are not using a three-pin,
non-reversible power
plug, please experiment
with the orientation of the
9
plug for optimum performance.
Burn-In and Warm-Up
Your Gryphon unit has
been thoroughly tested
and burned in before
shipping. Performance
will continue to improve
during the first 40 – 50
hours of normal use. After
this period optimum performance will be reached
approximately 45 minutes
after turn-on. With the
exception of Class A
power amplifiers, we recommend leaving your
Gryphon components
powered up at all times.
Balanced Connections
All Gryphon products
uses the AES standard for
balanced connections.
1. Ground
2. Positive
3. Negative
We recommend the use of
dedicated balanced
cables. Avoid the use of
adaptors as they degrade
performance.
Choice of Cables
Because your Kalliope is a
high-resolution Gryphon
audio device, it will immediately reveal the characteristics and possible limitations of the other components in your system, as
well as those of the interconnects and loudspeaker
cables used to connect
your system.
Wiring should never be
utilized as "equalizers" to
correct errors elsewhere
in the system. Instead, any
error should be corrected
at the source, so that interconnects and loudspeaker
cables can be selected
solely on the basis of
sonic neutrality. For this
reason, we employ
Gryphon's own range of
interconnects and cables
in every stage of the
design of every Gryphon
product.
Care and Maintenance
Gryphon products are
handcrafted by individuals who take great pride in
10
the high level of fit and finish which we achieve. To
maintain your Gryphon
components in pristine
condition, please follow
these simple instructions.
Metal surfaces may be
cleaned with a damp
cloth. Some product made
for treatment of vinyl interiors in cars may be useful. Test the product on a
non-visible surface,
before using any fluids.
Unpacking
During unpacking and
installation, please take
care to avoid scratching
the Gryphon Kalliope.
Hard, sharp objects such
as tools should not be
nearby during this
process. You might want
to remove your wristwatch, rings or other jewellery before handling
the preamplifier. Please
keep the carton and all
packing materials in a
dry place for safe future
transportation.
