Yamaha M-5000 S Power Amplifier - High-end 100-watt x2 (Silver)

Yamaha M-5000 S Power Amplifier - High-end 100-watt x2 (Silver) - Key Features The Yamaha M-5000 S Power Amplifier is the definitive expression of Yamaha’s flagship amplification philosophy — combining a floating balanced MOSFET circuit, a massive toroidal transformer, symmetrical low-impedance construction and precision-machined brass engineering to deliver 100 W×2 of extraordinary sonic authority, in perfect alignment with the C-5000 preamplifier and GT-5000 turntable. Strong, Reliable Power Output — Delivers 100 W 100 W into 8 Ω, 200 W 200 W into 4 Ω and up to 400 W in mono-bridge mode — with dynamic headroom of up to 500 W per channel into 2 Ω for demanding or inefficient speakers. Floating & Balanced MOSFET Circuit — Power supply connected directly to each positive and negative side of the output stage — completely floating the amplifier circuit from ground to eliminate voltage fluctuations, ground noise and improve drivability for low-impedance speakers. Symmetrical Low-Impedance Construction — Perfectly symmetrical layout physically and electrically isolating left and right channels, with short optimized signal paths, thick screw-type wiring and brass terminals directly on block capacitors for minimal energy loss and maximum signal fidelity. Massive Toroidal Core Transformer — Large toroidal transformer on a 3 mm pure brass base suppressing vibration and minimizing leakage flux — with copper wiring drawn directly from the winding core for a markedly low-impedance power delivery. Rigid Frame & Mechanical Ground Concept — Power transformer, block capacitors and heat sink bolted directly to the rigid chassis structure — maximizing rigidity, eliminating vibration influence and ensuring consistently optimal sonic performance. Broad Frequency Response & High Damping Factor — 10 Hz to 50 kHz frequency response with a damping factor of ≥300 for tight, controlled bass and exceptional clarity across the entire audio spectrum, from sensitive bookshelf speakers to large floorstanders. Exquisite Front-Panel Level Meters — Large, high-precision meters measuring 7 mm thick in Asahi glass visualize the full dynamics of the music — combining functional precision with an exceptionally elegant aesthetic befitting a flagship amplifier. Premier Speaker Terminals & Custom Brass Feet — Oversized screw-type speaker terminals cut from a solid brass block with a 3 mm non-magnetic pure brass base plate for distortion reduction and secure connection — custom heavy-duty brass feet functioning as decoupling spikes or with scratch-guard base for delicate surfaces. The power at the heart of Yamaha’s fully balanced flagship signal chain, the M-5000 redefines what a reference power amplifier can achieve. Whether driving the most demanding floorstanders or anchoring a precision high-fidelity system alongside the C-5000 and GT-5000, this Yamaha flagship amplifier delivers every watt with the control, authority and musical integrity that only true master craftsmanship can produce. Perfectly Balanced Together with the GT-5000 turntable and C-5000 pre-amplifier, Yamaha delivers an end-to-end balanced signal chain across its flagship models for premier performance.   Designed to Perform 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. Floating and Balanced Power Amplifier with MOSFETs 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.   Rigid Frame Structure Featuring a Mechanical Ground Concept 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. Massive Toroidal Core Transformer and Low Impedance Design 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 for Power Supply 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. Custom-designed Feet 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. Exquisite, Large Level Meters Reflect the Dynamics in the Music 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. Premier Speaker Terminals The M-5000 utilises oversized, screw-type speaker terminals to ensure ease-of-use and a secure connection. Cut from a pure brass block, the original Yamaha design denotes a meticulous attention to detail and premier quality. The 3 mm thick terminal base plate is also made from pure brass for strength and rigidity, and assists in reducing distortion due to its non-magnetic properties.
