Over the 130 years of its existence, Yamaha has become the world’s largest manufacturer of musical instruments and audio equipment. The Yamaha M-5000 amplifier embodies the spirit of time-honed craftsmanship, which, combined with market-leading innovation, makes it a model of high-fidelity audio reproduction.
The Yamaha M-5000 uses a sophisticated, fully symmetrical design in which the left and right channels are physically isolated and separated into separate electrical circuits. The deliberately simple component layout, which is also designed to minimize the signal path, reduces power loss and provides the low impedance needed for high-quality playback.
Unlike traditional amplifiers, in which power is supplied through a high-power transistor and the negative is connected to ground, the Yamaha M-5000 connects directly to each positive and negative side of the output stage. Complete isolation of the entire power amplifier circuit eliminates all unwanted effects of transient voltage fluctuations and ground noise. This symmetrical design is also ideal for MOSFET power amplifiers and improves amplification performance for low-impedance speaker systems.
The Yamaha M-5000 amplifier is designed from the ground up for maximum rigidity to reduce unwanted vibration and ensure optimal performance. In addition, the use of a mechanical grounding concept, implemented by bolting the power transformer, blocking capacitors and heatsink directly to the rigid structure, ensures complete component support and eliminates the effects of vibration.
The massive toroidal core transformer promotes superior sound reproduction and features a 3mm thick brass base to suppress unwanted vibrations. In addition, the power transformer does not affect the surrounding sound circuits, since it has low leakage flux. Copper wires removed from the core windings help reduce impedance, significantly reducing energy loss compared to traditional designs.
The thick wires and screw connections used in the Yamaha M-5000 amplifier help reduce impedance, reducing the energy loss that typically occurs with traditional connections and wiring. The use of screws and brass terminals located directly on the blocking capacitors, rather than soldering, provides a reliable, low-impedance connection.
The use of screws and brass terminals located directly on the blocking capacitors, rather than soldering, provides a reliable, low-impedance connection. And the legs were no exception. The original, sturdy brass feet act as full support for the device and can also be used in combination with pads to protect delicate surfaces from scratches.
The front panel of the Yamaha M-5000 amplifier features large, highly accurate level meters that allow listeners to visually monitor the dynamics of the music. These quality 7mm thick Asahi glass meters complement the luxurious and exceptionally sleek appearance of the Yamaha M-5000 amplifier.
The Yamaha M-5000 uses oversized screw terminals to ensure ease of use and reliable connections. The terminals are made from a solid block of brass. Original Yamaha design is characterized by meticulous attention to detail and premium quality. The 3mm thick base is also made of pure brass, a strong and rigid material. It helps reduce distortion due to its non-magnetic properties.
