YAMAHA REKINDLES THE HIGH-END WITH THE C-5000 PRE-AMPLIFIER AND M-5000 POWER-AMPLIFIER

Yamaha has today announced a suite of flagship amplifier models, including the C-5000 pre-amplifier, and M-5000 power-amplifier, each pushing the boundaries and showcasing Yamaha's capabilities as a world-class manufacturer.

C-5000 Pre-Amplifier

C-5000 Pre-Amplifier

The C-5000 features fully balanced and discrete circuit transmission across all stages of the signal path at Tone Defeat. The patented floating design is adopted across the phono EQ, input amp and line amp stages – removing the influence of ground noise from the signal.

Adopting independent dual toroidal transformers for the left and right channels delivers optimal separation and therefore producing a sound stage which is faithful to the original source. Low magnetic leakage lowers adverse impact on the audio signal. Following detailed research based on trial listening, the power transformer was enclosed in a copper-plated case to suppress magnetic flux and vibration. This also assists in minimising the influence of flux in the phono circuit. This realises a gentle, calm and even spacious sound due to enhanced reproduction of detailed signals.

By copper-plating the chassis to minimise the influence of voltage on the circuit, the C-5000 is capable of expressing the subtlest nuances as well as powerful bass. Additionally, thick screw-type wires are utilised to reduce the impedance of the power supply and maximises the transmission of musical information.

The C-5000 was designed from the ground up to deliver the ultimate in listening experiences – down to its aesthetic and even its touch. The knobs and lever switches feature original designs to communicate both innovation and craftsmanship. The volume knob is both rigid and precise – employing ball-bearings and precision-cut aluminium to achieve its touch while the lever switches have also been refined for enhanced operation.

Every aspect of the C-5000 was carefully considered when designing this flagship model. Its construction exudes master craftsmanship and reflects an obsession with achieving the highest levels of performance. The feet are no exception. Like the M-5000, the custom heavy-duty brass feet function either as fully supported spikes or with a scratch guard base for use on delicate surfaces.

M-5000 Power-Amplifier

Meticulously designed, the M-5000 adopts a perfectly symmetrical layout to isolate the left and right channels both physically and electrically. The deliberately simple design which also serves to reduce the signal path as much as possible, minimises energy loss and achieves lower impedance for high-fidelity performance.

As opposed to conventional power amplifier designs whereby power is supplied via a power transistor and the negative polarity is connected to ground, the power supply of the M-5000 is connected directly to each positive and negative side of the output stage. Completely floating the entire power amp circuit from the ground removes any undesirable impact of minute voltage fluctuations or ground noise. The design also creates an ideal symmetrical layout for employing MOSFET power amplifiers, improving drivability for low impedance speakers.

The M-5000 has been designed from the ground up to maximise rigidity – reducing unwanted vibration for optimal sonic performance. Further, employing a mechanical ground concept by fixing the power transformer, block capacitors and heat sink directly to the rigid streamlined construction with bolts ensures they are fully supported and eliminates the influence of vibrations.

Delivering high-fidelity performance, a massive toroidal transformer is utilised with a 3 mm thick pure brass base which suppresses unwanted vibrations. In addition, the power transformer does not influence the surrounding audio circuits due to less leakage flux. The drawn-out copper wiring from the winding core contributes to the low impedance design by markedly reducing the loss of energy when compared to conventional designs.

Thick wires and screw-type connections contribute to the low-impedance design of the M-5000 – minimising energy loss that would otherwise typically occur in conventional connections and wire assemblies. The use of screws and brass terminals directly on the block capacitors as opposed to solder promotes a strong, low impedance connection.

All aspects of the M-5000 design were considered in producing this flagship model. Its construction exudes master craftsmanship and reflects an obsession with achieving the highest levels of performance. The feet are no exception. Original in its design, the heavy-duty brass feet function either as fully supported spikes or with a scratch guard base for use on delicate surfaces.

The M-5000 features large, high-precision meters on the front panel, enabling audiences to visualise the dynamics of the music. Measuring 7 mm thick and made from Asahi glass, these quality meters only enhance the luxurious and exceptionally elegant aesthetic of the M-5000.

Meticulously symmetrical in its internal design, left and right channels are isolated both physically and electrically. The deliberately simple layout also serves to reduce the signal path as much as possible to minimise energy loss and achieve lower impedance.

The M-5000 features thick wires and screw-type connections which Yamaha says contributes to the low-impedance design, which minimises the loss that would otherwise typically occur in conventional connections and wire assemblies.

The C-5000 and M-5000 will be available in Black, or Silver with Piano Black wood side-panels.
