The Gryphon
takes compact disc to the next
level with the latest generation 96
kHz upsampling circuitry.
The Gryphon CDP1 was the
world’s first CD player to offer
advanced 88,2 kHz upsampling
technology in a single-chassis
transport/converter. This innovation was immediately recognized
as an amazing technological
“This enhancement elevates the
resolution of ordinary CD’s to a
previously unachievable level.”
(Audio magazine, Germany).
“A marvelous sonic calm and
clarity fill the room, with sweet
precision and openness.”
“If all CD players were as good,
we probably wouldn’t need any
new audio formats.”

upsampling, obviously, cannot
reconstruct lost information or generate “new” information, it will subjectively seem that this is
the case, because properly executed sample rate
conversion in the Gryphon
Adagio creates optimal working
conditions for the digital and analog circuits, allowing them to
more accurately reproduce the
information that is encoded on
the disc.
Through upsampling, aliasing
noise is shifted upwards in frequency and the upper corner frequency of the digital anti-aliasing
filters will be more than doubled
compared to the standard
44.1kHz sample rate. The analog
filter following the digital-to-analog converters can then be a simple first order filter with substantially improved sonic characteristics.
For these reasons, upsampling
in the Gryphon Adagio
enhances impulse
response, resolution of fine
detail, image focus and
high-frequency extension in
comparison with conventional 44.1kHz D/A conversion.
Uncompromising Design
Other key factors contribute to
the exceptional level of sonic resolution achieved in the Gryphon
Adagio. It is a strictly symmetrical, dual mono configuration with
both channels fully independent
from the C-core transformer to
the audio outputs. Equally
impressive is the selection of
employed from the power supplies to the voltage regulation
straight through to the lavishly
engineered output stages.
Gryphon Adagio features separate analog and digital power
supplies and an absolute minimum of internal wiring. The digital
power supply has its own separate transformer with four sec-
ondary windings for optimal electrical separation and noise suppression. Local filtering and regulators ensure optimal working
Master Clocks
Most CD players employ a single
basic clock oscillator placed near
the CD transport to supply the
clock signal to the transport, digital filter and D/A converter.
Unfortunately, allowing
the oscillator from the
CD transport to
generate the overall master clock
introduces both
mechanical and
electrical jitter.
To effectively eliminate this serious source
of sonic degradation, Gryphon
Adagio takes a radically different
approach to these crucial timing
(jitter) issues with separate local
master clocks placed near the
CD transport and D/A converters.
With independent, specially
designed, temperature-compensated crystal oscillators with
accuracy better than 5 parts per
million and an asynchronous
sample rate converter, the
Gryphon Adagio transport mechanism is completely isolated
from the conversion process,
keeping jitter at an absolute
The oscillators have their
own separate low-noise
power supply with independent supply and ground planes on
the printed circuit board.
In lesser players, timing errors
cause a "blurring" of fine detail
and intertransient silences, especially in fast passages with rapid
dynamic variations, such
as solo piano. Gryphon
Adagio keeps the
sonic image in ultrasharp focus.
The upsampled digital signal is then directed to 4 stereo
24/96 D/A bitstream converters in
a special Dual Differential coupling for a 3 dB improvement in
dynamic range, as well as significantly reduced noise.

The analog signal passes
through an absolute minimum of
components via the shortest possible signal path. The analog output stage employs a non-invasive
100 kHz first order output filter to
effectively remove high-frequency aliasing distortion. The filter, a
Polypropylene capacitor with
very high slew rate and tight tolerances, was selected following
extensive listening sessions for
its minimal influence on the audio

Gryphon Audio Designs
The main printed
circuit board is a 4layer
board with a 70mu
copper trace to ensure
power distribution and signal transfer. All resistors in
the analog outputs are SMD
(Surface Mount Device) types
with low induction and excellent
audio performance.
Each channel has its own power
supply with custom-made C-core
transformer, film capacitors and
fast electrolytic capacitors with
low ESR/ESL (inner resistance
and induction). In addition, the
most sensitive components incorporate local filtering.
