Exceptionally high performance 32-bit D/A converter
The D/A converter for the CD-S3000 is the
ES9018 from ESS Technology, Inc. We selected
this after careful examination of all points—not
only its high-precision processing of 32-bit
audio, but also the ability to handle large amounts
of audio data, strength in the low register, and
high-quality definition in the high register. Since
it is constructed with the master clock inside the D/A converter, it is also
features an original Jitter Eliminator function, permitting D/A conversion
with extremely low impact of clock jitter. Moreover, an 8-channel D/A
converter is housed inside the chip, and applies double differential
operation using 4-channel D/A converters on the right and left sides
respectively. It delivers exceptional high performance and high-quality
signal output with superior signal-to-noise ratio, since it employs an
analogue signal processing circuit with balanced configuration.
ASIO 2.0 Yamaha Steinberg USB Driver
The CD-S3000 supports the ASIO 2.0
protocol to take full advantage of the sound
quality of the USB DAC function. The
ASIO 2.0 protocol is a standard protocol for
professional use digital audio or DTM, with
a significant sound quality benefit: the ability
to achieve lower delay and higher throughput
than with a standard OS sound driver. The driver software is the ASIO
2.0 Yamaha Steinberg USB Driver
*, and allows high quality playback
of digital audio data stored to computer.
*The software is available as a free download from the Yamaha web site.
Pure Direct Mode further enhances
the quality of analogue sound
The CD-S3000 incorporates a special Pure Direct Mode: When playing
back analogue audio, the display is turned off and the digital output
circuitry is stopped, improving the quality of analogue output. This enables
a warmer, more natural sound with greater musicality, further enhancing the
value of a fully balanced connection with the A-S3000.
instrument manufacturer. The player with its refined design has been
meticulously finished by skillful use of advanced processing technologies:
integrating the top panel and side wood connection, leaving no gaps while
using different materials—metal and wood—for the connection. On the
CD tray, the gap between the front panel and the tray is uniformly precise.
Moreover, the beautifully finished half-mirrored glass window of the
display is precision-fit to the front panel smoothly without gaps—lending
an exceptionally elegant appearance to the unit.
Meticulously designed and beautiful in appearance—
just like a musical instrument
As befits a top-end audio component, the CD-S3000 gives off the presence
of a fine musical instrument, with absolutely no screws or fasteners that can
be seen from the outside. Every single aspect of its construction and design
exudes master craftsmanship and reflects an obsession with quality—a
truly musical quality possible only for Yamaha, a world class musical
Remote control with simple design and
superior texture
The supplied remote control is designed in the same way as
the aluminium panel of the CD player itself, with a simple,
easy-to-understand button layout and gorgeous metallic
texture. In addition to the basic CD track selection and play
controls, it can also be used to adjust the volume and switch
input sources on the companion A-S3000.
Built-in USB DAC functions
With high-resolution audio sources becoming more and more common
today, we designed the CD-S3000 for optimum enjoyment of those sources
with superior D/A conversion and the unit’s balanced signal output, and
equipped it with a built-in USB DAC function which allows direct input
of digital audio (from a computer, etc.) through a USB terminal. The USB
DAC employs an original IC, developed specifically for Yamaha. It has
an internal master clock, and can perform low-jitter transmission based on
asynchronous transmission, or receiving
signals without being synchronised with
the master clock in the PC. The unit is
compatible with digital audio of up to
192kHz/24-bit resolution.
Digital/analogue boards with
integrated power supply circuits
The internal design of the CD-S3000 does not separate the power
supply circuit boards, which include the power transformer; the block
capacitors are mounted directly on the respective digital/analogue
circuit boards. Thus, an original board configuration which integrates
the power supply circuits was adopted. Eliminating cabling from the
balanced transmission with a circuit configuration marked by symmetrical
plus and minus sides. Using a balanced connection with the A-S3000
Floating and Balanced Power Amplifier lets you enjoy profoundly pure
sound reproduction without any impact of transmission loss.
Single-stage configuration I/V conversion circuit enables
direct analogue output
To thoroughly eliminate audio signal loss, the CD-S3000 adopts an
innovative circuit configuration for the analogue circuit. The signal
from the D/A converter is conventionally output as an analogue signal
through an I/V conversion circuit configured in multiple stages. However,
in the CD-S3000, the signal is output by a single-stage configuration
based on a discrete design of the I/V conversion circuit. This single-
stage configuration with high slew-rate sharply lowers audio signal
loss compared to a multi-stage configuration circuit, and lowers NFB
(Negative Feedback), eliminating any sonic suppression, resulting in a
natural, spacious sound. The circuits beyond these D/A converters perform
Independent configuration of digital and analogue circuits
The CD-S3000 has adopted a twin power transformer method, which
completely separates the digital and analogue circuits from the power
supply and equips each with its own dedicated power transformer.
Separating the digital/analogue circuits from the transformer eliminates
sound quality deterioration caused by interference and noise between
the digital and analogue circuit blocks, which
occur when there is one digital/analogue power
supply. This results in exceptionally clear and
low-noise reproduction of analogue audio. The
power transformer is a toroidal transformer
with low magnetic leakage which, for both
the digital and the analogue units, lowers
adverse impact on the signal read from the
disc. Following detailed research based on trial
listening, we enclosed the power transformer
in a copper-plated case, in order to reduce the
impact of magnetic leakage and vibration. This realises a gentle, calm
and even spacious sound, due to enhanced reproduction of detailed
signals. This is one of the main aims of the S3000 series, to make sure
that even gentle, soft sounds, such as those of stringed instruments, are
reproduced accurately with rich expressive power.

power supply circuits to each circuit board and mounting directly
have the benefit of reducing connection loss, as well as achieving low
impedance. Moreover, cabling from the power transformer utilises the
same screw-type connections we’ve given the companion A-S3000
Integrated Amplifier. Connecting directly without soldering achieves
thorough contact point loss and low impedances.
