Yamaha M-5000 Power Amplifier

Yamaha M-5000 Power Amplifier With over 130 years of expertise, Yamaha has established itself as the world’s foremost sound company. The M-5000 exemplifies this legacy, blending traditional craftsmanship with cutting-edge innovation to deliver superior high-fidelity audio. 200 W + 200 W (4 ohm, 20 Hz-20 kHz, 0.07% THD, 2-channel driven) 100 W + 100 W (8 ohm, 20 Hz-20 kHz, 0.07% THD, 2-channel driven) Precision-engineered, balanced signal transmission Floating and balanced power amplifier design for enhanced drivability Symmetrical layout for isolating left and right channels Low impedance design with minimized signal and power supply paths State-of-the-art construction for increased rigidity Powerful toroidal core power transformer When paired with the GT-5000 turntable and C-5000 preamplifier, Yamaha provides a completely balanced signal chain for top-tier performance. Designed for Ultimate Performance The M-5000’s meticulous design includes a symmetrical layout that physically and electrically isolates the left and right channels. This simplicity reduces signal path length, minimizes energy loss, and achieves lower impedance for true high-fidelity sound. Floating and Balanced Power Amplifier with MOSFETs Unlike conventional amplifiers, the M-5000’s power supply is directly connected to both positive and negative sides of the output stage. This floating design eliminates the effects of voltage fluctuations and ground noise, while the symmetrical layout optimizes MOSFET power amplifier performance, enhancing drivability for low impedance speakers. Rigid Frame Structure and Mechanical Ground Concept Designed from the ground up for maximum rigidity, the M-5000 reduces unwanted vibrations for superior sound quality. By securing the power transformer, block capacitors, and heat sink directly to the rigid frame with bolts, Yamaha ensures stability and minimizes the influence of vibrations. Massive Toroidal Core Transformer and Low Impedance Design A massive toroidal transformer with a 3 mm-thick pure brass base minimizes vibrations and reduces leakage flux, ensuring high-fidelity performance. The low impedance design, with drawn-out copper wiring from the winding core, significantly reduces energy loss compared to conventional designs. Thick Wires and Screw-Type Connections for Power Supply Using thick wires and screw-type connections, the M-5000 minimizes energy loss that typically occurs with conventional connections. Screws and brass terminals on the block capacitors ensure strong, low-impedance connections. Custom-Designed Feet Every detail of the M-5000, including its custom heavy-duty brass feet, reflects Yamaha’s dedication to craftsmanship and performance. These feet can be used as fully supported spikes or with a scratch guard base for delicate surfaces. Exquisite, Large Level Meters Featuring large, high-precision meters made from 7 mm-thick Asahi glass, the M-5000 allows listeners to visualize the dynamics of the music, enhancing its luxurious and elegant aesthetic. Premier Speaker Terminals Oversized, screw-type speaker terminals ensure secure connections and ease of use. Crafted from pure brass, these terminals exemplify Yamaha’s attention to detail and commitment to premier quality, with a 3 mm-thick pure brass base plate for added strength and reduced distortion.
