CD-S3000 adopts a twin power transformer, which completely separates the digital and analogue circuits from the power supply and equips each with its own dedicated power transformer. This eliminates sound quality deterioration caused by interference between circuit blocks resulting in exceptionally clear and low-noise reproduction of analogue audio.
The toroidal transformer with low magnetic leakage, for both digital and analogue units lowers adverse impact on the disc signal. It is enclosed in a copper-plated case to reduce magnetic leakage and vibration for a gentle, calm and even spacious sound. This is one of the series’ main aims of to ensure that even soft sounds are reproduced accurately with rich expressive power.
To thoroughly eliminate audio signal loss, CD-S3000 adopts an innovative circuit configuration for the analogue circuit. 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 negative feedback resulting in a natural, spacious sound. The circuits beyond these DACs perform balanced transmission with a circuit configuration marked by symmetrical +/- sides.
Exceptional 32-bit DAC
ESS Technology’s ES9018 DAC was chosen for its high-precision 32-bit audio processing as well as its ability to handle large amounts of data, low register strength and high register premium-quality definition. It also features an original Jitter Eliminator function, permitting D/A conversion with extremely low impact of clock jitter.
An 8-channel DAC is housed inside the chip, and applies double differential operation using 4-channel DACs on the right and left sides respectively. It delivers high-quality signal output with superior signal to noise ratio thanks to the balanced analogue signal processing circuit.
Built-in USB DAC
Designed for optimum enjoyment of high-res audio sources with superior D/A conversion, balanced signal output and a built-in USB DAC function, CDS3000 allows direct digital audio input (from PC etc) via USB. This employs a specially developed original IC, with an internal master clock and low-jitter transmission capability, supporting up to 192kHz/24-bit resolution.
ASIO 2.3 protocol takes full advantage of the USB DAC function sound quality. It is a standard protocol for professional use digital audio or DTM offering the ability to achieve lower delay and higher throughput than a standard OS driver. The driver software allows high quality playback of digital audio data stored to computer.
Integrated power supply
The internal design 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. Eliminating cabling from the power supply circuits to each circuit board and mounting directly has the benefit of reducing connection loss and achieving low impedance. Cabling from the power transformer uses the same screw type connections as the A-S3000.
Pure Direct Mode
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.
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.
CD-S3000 gives off the presence of a fine musical instrument with absolutely no screws or fasteners seen from the outside. Every single aspect of its construction and design exudes master craftsmanship and reflects an obsession with quality.
The refined design has been meticulously finished using advanced processing technologies: integrating the top panel and side wood connection, leaving no gaps despite using different materials. The half-mirrored glass window of the display is precision-fit to the front panel lending an elegant appearance to the unit.
The supplied remote control is designed in the same way as the aluminium panel, with a simple, easy-to-understand button layout and metallic texture. In addition to basic CD track selection and play controls, it can be used to adjust the volume and switch input sources on the A-S3000.
