Yamaha CD-S2100, High-Grade CD 1CD Player (Black / Silver)

Left-Right Symmetrical Construction, Independent Digital/Analog Circuit Configuration

The CD-S2100 has a 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 play.

Digital/Analog Circuitry with Integrated Power Supplies and Screw-Type Connections Eliminate Signal

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 that 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 as the companion A-S2100 Integrated Amplifier has. Connecting directly without soldering achieves thorough contact point loss and low impedances.

Single-Stage Configuration I/V Conversion Circuit Enables 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 D/A converter 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 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 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 Analog

The CD-S2100 has adopted a twin power transformer method, which completely separates the digital and analog circuits from the power supply and equips each with its own dedicated power transformer. Separating the digital/analog circuits from the transformer eliminates sound quality deterioration caused by interference and noise between the digital and analog circuit blocks, which occur when there is one digital/analog power supply. This results in exceptionally clear and low-noise reproduction of analog audio. The power transformer is a toroidal transformer with low magnetic leakage which, for both the digital and the analog units, lowers adverse impact on the signal read from the disc.

High Precision CD Drive for Vibration Resistance and High Precision Signal Reading

The CD-S2100 is equipped with a loader mechanism that 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 provides 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 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. Yamaha has fine-tuned the opening/closing action by adding a specially designed meshed wire drive, achieving smoother and gentler operation.

32-bit D/A Converter

The D/A converter for the CD-S2100 is the ESS Technology ES9016 SABRE Reference Stereo DAC. Yamaha selected this after 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 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 high performance and high-quality signal output with superior signal to-noise ratio, since it employs an analog signal processing circuit with balanced configuration.

Built-in USB DAC Functions and ASIO 2.3 Yamaha Steinberg USB Driver

The CD-S2100 is equipped with a built-in USB DAC function that allows direct input of digital audio (from a computer) 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 synchronized with the master clock in the PC. The unit is compatible with digital audio of up to 192 kHz/24-bit resolution. It 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 ASIO 2.3 Yamaha Steinberg USB Driver is available from Yamaha's website.

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 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.

Sleek Design and Half-Mirror Display

The CD-S2100 has no visible screws or fasteners from the outside. The amplifier has been finished by the skillful use of advanced processing technologies, integrating the top panel and side wood connection, leaving no gaps while using different materials for the connection.

Remote Control

The supplied remote control features a design complementary to the aluminum panel of the CD player itself, with a simple, easy-to-understand button layout and metallic texture. In addition to the basic volume adjustment and input switching controls of the CD-S3000, it can also be used for operation of the companion A-S2100.
