Left-right symmetrical construction, independent
digital/analogue circuit configuration, with top priority on sound quality
The CD-S2100 has completely symmetrical construction: the
rotating loader mechanism is in the centre, the digital power supply and
circuit board are on the left side, and the analogue power supply and circuit
board are on the right. Completely isolating the digital unit and the analogue
unit eliminates detrimental impacts of interference between the circuits, while
achieving ideal weight balance. The centre frame that extends from the front to
the back of the body and the front panel made of 5mm (1/4”) thick aluminium
increases rigidity of the entire chassis and ensures stable disk play.
Digital/analogue circuitry with integrated power supplies
and screw type connections eliminate signal transmission loss
The internal design of the CD-S2100 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 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-S2100 Integrated Amplifier. Connecting directly without soldering
achieves thorough contact point loss and low impedance. Signal is transmitted
to the amp without loss of any information that has been read, delivering sound
reproduction filled with a sense of energy and crisp openness—the over-arching
aim of the S2100 Series.
Single-stage configuration I/V conversion circuit enables
direct analogue output
To thoroughly eliminate audio signal loss, the CD-S2100
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-S2100, 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
this D/A converter perform balanced transmission with a circuit configuration
marked by symmetrical plus and minus sides. Using a balanced connection with
the A-S2100 Floating and Balanced Power Amplifier lets you enjoy profoundly
pure sound reproduction without any impact of transmission loss.
Independent power supplies with complete separation of
digital and analogue
The CD-S2100 has adopted a twin power supply transformer
method, complete with separate, dedicated power supply transformers for the
digital and analogue circuits. Isolating the digital and analogue circuits
starting at the transformer step eliminates sound quality deterioration caused
by interference and noise between the digital and analogue units—a problem that
occurs when they share the same power supply. This results in exceptionally
clear, low-noise reproduction of analogue audio. Moreover, the power supply
transformer for the analogue circuit is a toroidal transformer that provides
stable power supply with low magnetic flux leakage, and the winding, stabilised
power supply circuit is completely isolated on the left and right sides. This
achieves superior separation—a particularly important point in Hi-Fi audio.
High precision CD drive for greater vibration resistance
and high-precision signal reading
The CD-S2100 is equipped with the same drive mechanism as
the Yamaha flagship model CD-S3000, in order to perform high-precision reading
of the vast quantity of audio data recorded on a disk. And the loader mechanism
is connected firmly to the chassis by installing heavy, specially specially
bent 1.6mm (1/16”) thick iron reinforcing anchors in front of and behind the
loader mechanism, eliminating the transmission of vibration caused by disk
rotation to the circuit board. In the process of assembling the CD-S2100, after
the drive mechanism has been attached to the chassis, horizontal fine
adjustment of each anchor is performed carefully. While this is troublesome, it
shows Yamaha’s commitment to providing the ultimate in precise signal reading.
By eliminating even the slightest tilting of the mechanism, this achieves
stabilised rotation and ultra-precise reading. Reducing the load of the servo
that drives the pickup and lowering the impact of change of servo amperage on
the signal, achieves clean signal read out with little impact of noise—drawing
out every little nuance the artist has recorded.
High rigidity aluminium CD tray
The CD tray is made of high rigidity aluminium, reducing
secondary vibrations due to resonance of the disc and the high-speed motor
rotating the disc, resulting in improved audio signal-reading precision and
quieter operation. In addition to the smart design and luxurious texture, we’ve
fine-tuned the opening/closing action by adding a specially designed meshed
wire drive, achieving smoother and gentler operation. We obsessively strove to
give the unit a luxurious operating feel that perfectly matches the superior
sound quality.
Exceptionally high performance 32-bit D/A converter
The D/A converter for the CD-S2100 is the ES9016 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 the built-in D/A converter
generates its own master clock, an original Jitter Elimination function is also
included, 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.
Built-in USB DAC functions, and ASIO 2.3 Yamaha Steinberg
USB Driver
For optimum enjoyment of today’s high-resolution audio
sources, we designed the CD-S2100 with superior D/A conversion and balanced
signal output, and equipped it with a built-in USB DAC function which allows
direct input of digital audio (from a computer, etc.). The USB DAC employs an
original IC, developed specifically for Yamaha. It has an internal master
clock, and can perform low-jitter transmission. The CD-S2100 supports the ASIO
2.3 protocol to take full advantage of the sound quality of the USB DAC
function. The ASIO 2.3 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 2.3 Yamaha Steinberg USB Driver*, and allows
high quality playback of digital audio data stored to computer. The unit is
compatible with digital audio of up to 192kHz/24-bit resolution and supports
DSD native playback.

*The software is available as a free download from the Yamaha web site.
Insulators allow use of spikes or pads
The insulators are crucial parts that block outside
vibrations. They adopt Yamaha’s original metal legs in order to maximise
vibration control performance. The user can select point installation by
applying the supplied spikes or plane insulation with the supplied pads, and
use these combined with an interlocking rack if desired.
Beautiful, sleek design and half-mirror display
Inside and out, the CD-S2100 fully demonstrates Yamaha’s
commitment to fine craftsmanship, and its long history as a premier maker of
musical instruments. In the connections between the front panel and the side
wood, masterful use of advanced processing technology beautifully integrates
different materials, metal and wood. On the CD tray, the gap between the front
panel and the tray is uniformly precise. The display unit is of half-mirror
design, with track information beautifully displayed during CD playback, and at
the same time, when the power supply is off, it harmonises beautifully with the
aluminium hair-line finish of the front panel.
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-S2100.
