Welcome to our world
Words by Flemming E. Rasmussen, CEO and
Founder of Gryphon Audio Designs
Two decades have passed
since the first Gryphon saw
the light of day. It wasn't a
case of planned parenthood,
more an inevitable love child the fruit of a long-standing
love affair with music and
audio.
Gryphon embarked on a long
journey back then, made long
not by detours, but simply
because our destination is so
far away. I have always believed that we experience
music with our hearts as much
as with our ears. For me, the
ultimate test is very simple the music must reach out and
touch the heart. Looking back
over the years, I must confess
that Gryphon has always
developed the audio products
that I personally needed and
wanted. Nothing was ever
built to meet a demand defined by market research.
Some might find that arrogant
and perhaps it is, but I prefer
to see it as an honest approach, while accepting that
not everyone shares my point
of view.
Fortunately, the passing years
have proven that there is a
sufficiently large group of likeminded individuals around the
world who have come together in this common quest.
I would like to take this opportunity to personally thank all
of you who have shared this
journey with me.
Down through the years,
Gryphon has expanded from a
single Head Amplifier to
encompass the full audio
spectrum with the definitive
music playback system. This
didn't happen because we can
do everything ourselves, but
because we recognize quality
when we encounter it and
have the ability to assemble a
team of dedicated specialists
for each new project. The
Gryphon company - like its
products - is greater than the
sum of its parts.
There is certainly a family
resemblance across the
Gryphon range and by that we
mean more than mere technology. We like to think that
Gryphon is not perceived as
Class A amplifiers, upsampling
CD players or silver cables,
but more as a degree of quality, a sense of "rightness" that
brings it all home for you. And
you don't reach that place by
following your ears, only by
following your heart.
In responding to queries as to
why Gryphon took the major
step of expanding into the
field of loudspeaker design,
the temptation is to take the
easy way out with a flippant
reply like "Because it's there."
But the simple fact is that,
having earned a global reputation for unsurpassed excellence in amplification, it was a
natural evolutionary move to
broaden our scope and turn
our attention to the other links
in the audio chain.
Flemming E. Rasmussen
Gryphon founder and CEO
Beginning with source components, Gryphon designed the
world's first single-chassis CD
player with onboard upsampling. The third generation of
this innovative technology, the
Gryphon Mikado, has won
numerous awards around the
world. The next logical step
was to apply the uncompromising Gryphon take-no-prisoners approach to the final link
in the chain. But this decision
was by no means made on the
spur of the moment.
In fact, the Gryphon speaker
adventure began nearly 18
years ago with a chance
encounter between Gryphon
founder Flemming E.
Rasmussen and Steen
Duelund, a Danish mathematician who has dedicated his
professional life to loudspeaker theory.
Duelund's theories on constant phase in crossover networks can be summed up in a
single statement: "All drivers
must be in phase at all times
at all frequencies." Following
this theoretical "Eureka," the
hard part then becomes
making that happen in a real
room with a real loudspeaker.
Initially on a strictly informal
basis, an in-depth exploration
was undertaken that would
take full advantage of
Gryphon's assembled expertise and extensive experience
in design and manufacturing
to transform Duelund's theories into real-world products
with scant regard for such
minor details as pricing, parts
availability, prevailing attitudes
and preconceived notions.
Steen Duelund passed away
in 2005 but the rest of the original design team implement
his ideas and spirit, as much
as possible, in every Gryphon
speaker project. Duelund left
a unique library of reference
recordings to Gryphon CEO
Flemming E. Rasmussen.
These recordings are still
used in all projects, allowing
us to imagine what the old
master would had said.
Mojo design observations
As with all things known to
man, loudspeakers are subject to the laws of physics and
to the limitations of human
perception. We may bend,
manipulate or mask or exploit
these laws and limitations, but
we cannot ignore them.
In the quest for the finest
speaker, music lovers audition
numerous models and finally
settle on what they believe to
be the “best” speaker. What
else can you do? But is the
“best speaker” truly the best
speaker? If you are lucky, you
will end up with a speaker that
is the best match for a particular room, a speaker that
might be a complete disaster
when set up in a different
room. This explains the differences in opinion about speaker performance. The performance/quality of any given
speaker changes radically,
depending on its environment.
