Direct Drawing Toroidal Transformer for Complete Elimination of Signal Transmission Loss

The cabling of the power transformer adopts an ingenious method in order to significantly reduce impedance. The winding of the transformer itself is directly connected to the terminal with a screw, unlike with conventional cabling. This enables a power supply which thoroughly limits connection loss and energy loss caused by soldering. The toroidal transformer was selected with top priority on sound quality, contributing superior strength, as well as a profoundly natural and spacious sound.

Superior Quality Electronic Volume Control for Optimum Sound

We’ve utilized a high-quality digital volume control specially designed by New Japan Radio Co., Ltd., which consists only of ladder-type resistance, removing the impact of slew-rate decline or coloring of the sound, delivering higher purity in the sound, and excellent, fast response to large volume changes and steep transients.

Discretely Configured Phono Amp

The phono amp is comprised of an MC head amp and an equalizer amp, each of which are discretely configured, resulting in a rich sound with pronounced musicality, when playing vinyl records with both MC and MM phone cartridges.

Original Speaker Terminals for High Sound Quality - as Well as Beauty and Ease of Use

The speaker terminals are the final link in the audio chain of this amplifier, and have also been designed with meticulous obsession. They are screw-type terminals with large handles featuring an original design, and have been crafted by cutting pure brass to enable a secure connection with no reduction in sound quality. Moreover, the shape conforms nicely to the human fingers—not only creating an elegant visual impression, but also allowing users to turn them easily and to firmly tighten them with minimal force.

Rigid Streamlined Construction Provides Strict Anti-vibration Protection and Enables Shortest Cabling Routes

The A-S3000 has adopted a newly designed highly rigid double structure construction in order to achieve profoundly pure and accurate audio amplification. The bottom chassis and insulator ward off external vibration, and provide each circuit board a floating structure supported by an independent inner frame, thoroughly eliminating the impact of vibration. And the power source unit, which consists of a power transformer and capacitors, which are major sources of internal vibration, is fixed firmly with a three-dimensional structured inner frame, and is supported solidly by the front panel and the rear panel.

Large Toroidal Transformer, Solidly Mounted with Independent Three-dimensional Inner Frame

An independent three-dimensional inner frame has been employed in order to provide a more solid mount for the large toroidal transformer, which is installed in the center of the A-S3000, considering the ideal weight balance. The completely copper-plated inner frame has a structure which integrates the front-back and left-right frames with a convex-shaped highly rigid main frame as its base, reducing vibration coming from all directions. For the base, to which the power transformer is installed on the inner frame, brass was selected by strictest examining the particular sonic properties of various materials by exhaustive listening tests. This material effectively reduces vibration caused by the power transformer, helping to create sound of greater clarity and spaciousness.


Exceptionally Low Impedance through Secure Screw Connections

In order to completely eliminate signal energy loss, important parts of even the circuits employ screw connections. In addition to wiring of the block capacitor of the power unit—which is the real heart of the amplifier and as such requires high power—screw connections were adopted for all crucial spots of signal transmission, including the connection of the preamp circuit with the power amp circuit, and the cabling to the speaker terminals from the output stage of the power amp. In addition to making the signal path as short as possible, this signifi cantly lowers the impedance, and greatly reduces signal loss.


Left-right Symmetrical Design for Independent Preamp and Power Amp Blocks

The amplifier circuit design features independent preamp and power amp blocks, and perfect left-right symmetry. Separation of the preamp, which handles low energy signals, from the power amp, which handles high-energy amplified signals, greatly reduces sound deterioration caused by mutual interference. Moreover, the left-right symmetrical design, which keeps the left and right power stages completely separate, ensures greater channel separation and enhances clarity of the stereo image.

Exquisite, Large Level Meters Reflect the Dynamics in the Music

The A-S3000 features large level meters on the front panel, giving a direct visual sense of the dynamics and pulse of the music. These beautiful meters are softly illuminated by LED, lending a warm, lamplight look. The meter indicators can, in addition to the VU display, be switched to peak display, and can be selected according to the user’s preference. Moreover, the glass window of the meters is diagonally cut and precision-fit to the back surface of the front panel, leaving no gaps and using no screws for connection—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 A-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 instrument manufacturer. The amplifier with its refined design has been meticulously finished by the 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.

Obsessive, Meticulous Switch Design — Elaborate, Richly Textured, Easy-to-Use

Since the controls—the volume dial, switches, and so on—are the parts of the amplifier which users actually touch and feel directly, their surface texture and design were created with the strictest attention to detail. Individual controls such as the volume or input switching dials, emanate a richly elegant feel thanks to the use of cut aluminum knobs. Switches, including the power switch, were made with obsessive attention to texture in every detail; they were shaped with refined craftsmanship so that when they are raised or lowered, the gap between the switch and panel surface is impossible to see.

Remote Control with Simple Design and Superior Texture

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

Independent Configuration of Digital and Analog Circuits

The CD-S3000 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.

Digital/Analog 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/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 screwtype connections we’ve given the companion A-S3000 integrated amplifier. 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-S3000 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-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 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 technology lets you enjoy profoundly pure sound reproduction without any impact of transmission loss.

Exceptionally High Performance 32-bit D/A Converter

The D/A converter for the CD-S3000 is the ESS Technology ES9018 SABRE32 Reference Sound/DAC™. 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 defi nition 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 analog signal processing circuit with balanced configuration.

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 synchronous transmission, or receiving signals without being synchronised with the master clock in the PC. The unit is compatible with digital audio of up to 192 kHz / 24-bit resolution.

ASIO 2.3 Yamaha Steinberg USB Driver

The CD-S3000 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.

Pure Direct Mode Further Enhances the Quality of Analog Sound

The CD-S3000 incorporates a special Pure Direct Mode. When playing back analog audio, the display is turned off and the digital output circuitry is stopped, improving the quality of analog output. This enables a warmer, more natural sound with greater musicality, further enhancing the value of a fully balanced connection with the A-S3000.

Optimized High-precision Rigid CD Mechanism with Heavy Anchors Improves Vibration Control and Achieves Ultra-precise Signal Reading

The CD-S3000 was created with meticulous care to ensure rigidity with superior vibration control properties and ultra-precise reading—to draw out all the music recorded to the disc. We incorporated a newly designed drive mechanism with added heavy anchors for Yamaha’s own original loader mechanism. Installing it on the chassis through the heavy anchors in front of and behind the loader mechanism achieves the highest rigidity and blocks the effects of vibrations from outside. At the same time, it also prevents vibration caused by rotation of the disc from affecting the circuit board. The anchor on the front features two layers and a screw-based adjustment mechanism. This allows for highly precise adjustment of the horizontal level of the front-back and left-right sides of the loader mechanism.

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, 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.


High Rigidity Main Chassis Improves Anti-vibration Properties and Left-right Symmetrical Construction

The main chassis, which supports the loader mechanism, was also made as strong as possible, and reinforcing each part improved the rigidity of the chassis itself. Moreover, the front panel is made of 0.28” thick aluminum, contributing to the high rigidity of the entire chassis. The unit is constructed by placing the loader mechanism, which is a rotating body, in the center, then placing the digital power supply and circuit board on its left, and the analog power supply and circuit board on its right, to achieve a total symmetrical structure with the digital and analog parts separated, achieving the ideal weight balance. Finally, to minimize impedance as much as possible, the bottom chassis, which is the standard ground, has been copper plated.


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, and are the same as used on the A-S3000. The user can select point installation by applying the supplied spikes or standard insulation with the supplied pads, and use these combined with an interlocking rack if desired.

Remote Control with Simple Design and Superior Texture

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 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.
