Analog & Digital Connectivity
High Rigidity Aluminum CD Tray: The CD tray is made of high rigidity
aluminum, 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, Yamaha has fine-tuned the opening/closing action by adding a specially
designed meshed wire drive, achieving smoother and gentler operation.
- Disc Compatibility: The Yamaha CD-S2100 supports
playback of SACD, CD, CD-R, and CD-RW discs.
- Super Audio CD: Super Audio CD use a technology called
Direct Stream Digital (DSD) to convert music into a digital signal that can
be stored on a disc. Compared to the traditional PCM method (the technology
used for CD), DSD offers a much higher resolution by following more closely
the original waveform of music. With a frequency response of over 100kHz and
a dynamic range over 120dB across the audible frequency range - some 64
times higher resolution then CD - Super Audio CD offers music reproduction
that reveals details you just cannot hear on a normal CD.
- MP3/WMA Music Files: This single disc CD player
supports MP3 (32-320kbps; up to 44.1kHz) and WMA (48-192kbps; up to 44.1kHz)
playback on CD-R and CD-RW discs compatible with ISO9660. The unit can
recognize up to 648 folder and files (combined) and up to 299 folders.
High Precision CD Drive: The CD-S2100 is equipped with the same drive
mechanism as the Yamaha flagship model CD-S2100 in order to perform high
precision reading of the vast quantity of audio data recorded on a disc. The
loader mechanism is connected firmly to the chassis by installing heavy,
specially curved 1/16" thick iron reinforcing anchors in front of and behind the
loader mechanism, eliminating the transmission of vibration caused by disc
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 difficult, it shows
Yamaha's commitment to providing the ultimate in precise signal reading. By
eliminating even the slightest tilting of the mechanism, this achieves
stabilized 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 readout with little impact of noise, drawing
out every little nuance the artist has recorded.
High-Peformance ESS 32-Bit DAC: The DAC (digital-to-analog converter)
for the CD-S2100 is the ES9016 from ESS Technology, Inc. Yamaha selected this
DAC not only because of its high precision processing of 32-bit audio, but also
due to its 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
DAC 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 analog signal processing circuit with balanced configuration.
Left-Right Symmetrical Construction: The CD-S2100 has completely
symmetrical construction; the rotating loader mechanism is in the center, the
digital power supply and circuit board are on the left side and the analog power
supply and circuit board are on the right. Completely isolating the digital unit
and the analog unit eliminates detrimental impacts of interference between the
circuits while achieving ideal weight balance. The center frame that extends
from the front to the back of the body, along with a front panel made of 1/4'
thick aluminum, increases rigidity of the entire chassis and ensures stable disc
Screw-Type Digital/Analog Circuitry: 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/analog 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 utilizes the same screw-type
connections Yamaha has 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.
Single-Stage Configuration I/V Conversion w/ Direct Analog Output: To
thoroughly eliminate audio signal loss, the CD-S2100 adopts an innovative
circuit configuration for the analog circuit. The signal from the DAC is
conventionally output as an analog 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 multistage configuration circuit and lowers NFB
(negative feedback), eliminating any sonic suppression resulting in a natural,
spacious sound. The circuits beyond this DACperform 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 due to
Independent Power Supplies For Digital & Analog Circuits: The CD-S2100
has adopted a twin power supply transformer method complete with separate,
dedicated power supply transformers for the digital and analog circuits.
Isolating the digital and analog circuits starting at the transformer step
eliminates sound quality deterioration caused by interference and noise between
the digital and analog units; a problem that occurs when they share the same
power supply. This results in exceptionally clear, low-noise reproduction of
analog audio. Moreover, the power supply transformer for the analog circuit is a
toroidal transformer that provides stable power supply with low magnetic flux
leakage. The stabilized power supply circuit is completely isolated on the left
and right sides. This achieves superior separation - a particularly important
point in Hi-Fi audio.
Sophisticated, Sleek Design: Inside and out, the CD-S2100 fully
demonstrates Yamaha's commitment to fine craftsmanship and its long history. 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. When the power supply is
off, it harmonizes beautifully with the aluminum hairline finish of the
Insulator Feet w/ Spikes or Pads: The insulators are crucial parts
that block outside vibrations. They adopt Yamaha's original metal legs in order
to maximize 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.
Analog & Digital
Built-in USB DAC: With high resolution audio sources
becoming more and more common today, Yamaha designed the CD-S2100 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 (type-B)
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 synchronized
with the master clock in the PC. The unit is compatible with digital audio of up
to 192kHz/24-bit resolution.
- Windows & Mac Compatible: The player's USB connection
will support Windows Vista (SP2; 32-/64-bit), Windows 7 (32/64-bit), and
Windows 8 (32-/64-bit). It also supports Mac OS X 10.5.8 through 10.8x.
- ASIO 2.3 Yamah Steinberg USB Driver: 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 software is available as a free download from the
Yamaha web site.

This enables a warmer, more natural sound with greater musicality, further
enhancing the value of a fully balanced connection with the A-S2100.
DPLL (Digital Phased Lock Loop): The audio DAC (ES9016) of
this unit employs DPLL to generate accurate clock signals synchronized with the
clock of the input digital audio signal. The 7-step DPLL bandwidth setting gives
the unit tolerance for fluctuation of the clock of the input digital signal and
adjustment of the accuracy of the operating clock in the DAC.
Remote Control: The supplied remote control is designed in the same
way as the aluminum panel of the CD player itself, with a simple,
easy-to-understand button layout and gorgeous metallic texture. In addition to
