The improved design provides excellent reliability and stability
Massive transformer with toroidal core

Perfect balance

Yamaha provides premium sound quality by transmitting balanced signals between its flagship line of models, which also includes the GT-5000 player and the C-5000 preamp.

Ideally efficient design

The M-5000 uses an elaborate, fully symmetrical design in which the left and right channels are physically isolated and separated by separate electrical circuits.

The deliberately simple component layout, which is also designed to minimize the path that the signal travels, reduces energy loss and provides the low impedance required for high-quality reproduction.

Symmetrical power amplifier with "floating" power supplies and field-effect MOSFETs

Unlike traditional amplifiers, in which power is supplied through a high-power transistor, and the "minus" is connected to the ground, the M-5000 is connected directly to each positive and negative side of the output stage.

Complete isolation of the entire circuit of the power amplifier eliminates all undesirable effects of short-term voltage fluctuations and interference from the ground.

This symmetrical design is also ideal for MOSFET power amplifiers and improves the gain quality for low-impedance speakers.

Reinforced rigid frame construction with the concept of mechanical grounding

The design of the M-5000 amplifier is designed from the ground up with the expectation of maximum rigidity in order to reduce unwanted vibrations and ensure optimal playback quality.

In addition, the application of the concept of mechanical grounding, implemented by attaching the power transformer, locking capacitors and radiator directly to the rigid structure with bolts, provides full support for the components and eliminates the influence of vibrations.

Massive low-impedance transformer with a toroidal core

A massive transformer with a toroidal core, contributing to the reproduction of sound of the highest quality, is equipped with a brass base 3 mm thick, suppressing unwanted vibrations.

In addition, the power transformer does not affect the surrounding sound circuits, since it has a small scattering flux.

Copper wires removed from the core winding help to reduce the impedance, significantly reducing energy losses compared to traditional designs.

Thick wires and screw power connections

The thick wires and screw connections used in the M-5000 amplifier help to reduce impedance, reducing energy losses that usually occur on traditional connections and wiring.

The use of screws and brass terminals located directly on the locking capacitors, rather than spikes, ensures a reliable connection with low impedance.

Specially designed legs

The use of screws and brass terminals located directly on the locking capacitors, rather than spikes, ensures a reliable connection with low impedance.

And the legs were no exception. The original legs made of strong brass act as fully supporting stops, and they can also be used in combination with linings that protect delicate surfaces from scratches.

Large chic level indicators reflect the dynamics of the music

Large high-precision level indicators are placed on the front panel of the M-5000 amplifier, with which listeners can visually monitor the dynamics of the music.

These high-quality indicators with Asahi glass, 7 mm thick, complement the luxurious and exceptionally elegant appearance of the M-5000 amplifier.

Premium outputs for speaker systems

The M-5000 model uses larger screw terminals to ensure ease of use and reliability of connections. The terminals are made of a single bar of brass. The original Yamaha design is distinguished by scrupulous attention to detail and premium quality.

The base with a thickness of 3 mm is also made of pure brass - a strong and rigid material. It helps to reduce distortion due to the absence of magnetic properties.
