The M-5000 embodies this spirit with time-honoured craftsmanship and market-leading innovation and serves as the epitome of high-fidelity audio reproduction.\u003cbr\u003e\u003cbr\u003e\n•200 W + 200 W (4 ohm, 20 Hz-20 kHz, 0.07% THD, 2-ch driven)\u003cbr\u003e\n•100 W + 100 W (8 ohm, 20 Hz-20 kHz, 0.07% THD, 2-ch driven)\u003cbr\u003e\n•Meticulously designed, balanced signal transmission\u003cbr\u003e\n•Floating and balanced power amplifier layout for improved drivability\u003cbr\u003e\n•Perfectly symmetrical design for isolating left and right channels\u003cbr\u003e\n•Low impedance design with shortened signal and power supply paths\u003cbr\u003e\n•Improved construction delivers state-of-the-art rigidity\u003cbr\u003e\n•Massive toroidal core power transformer\u003cbr\u003e\u003cbr\u003e\n\nPerfectly Balanced\u003cbr\u003e\nTogether 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.\u003cbr\u003e\u003cbr\u003e\n\nDesigned to Perform\u003cbr\u003e\nMeticulously designed, the M-5000 adopts a perfectly symmetrical layout to isolate the left and right channels both physically and electrically.\nThe 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.\u003cbr\u003e\u003cbr\u003e\n\nFloating and Balanced Power Amplifier with MOSFETs\u003cbr\u003e\nAs 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.\nCompletely floating the entire power amp circuit from the ground removes any undesirable impact of minute voltage fluctuations or ground noise.\nThe design also creates an ideal symmetrical layout for employing MOSFET power amplifiers, improving drivability for low impedance speakers.\u003cbr\u003e\u003cbr\u003e\n\nRigid Frame Structure Featuring a Mechanical Ground Concept\u003cbr\u003e\nThe M-5000 has been designed from the ground up to maximise rigidity - reducing unwanted vibration for optimal sonic performance.\nFurther, 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.\u003cbr\u003e\u003cbr\u003e\n\nMassive Toroidal Core Transformer and Low Impedance Design\u003cbr\u003e\nDelivering high-fidelity performance, a massive toroidal transformer is utilised with a 3 mm thick pure brass base which suppresses unwanted vibrations.\nIn addition, the power transformer does not influence the surrounding audio circuits due to less leakage flux.\nThe 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.\u003cbr\u003e\u003cbr\u003e\n\nThick Wires and Screw-type Connections for Power Supply\u003cbr\u003e\nThick 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.\nThe use of screws and brass terminals directly on the block capacitors as opposed to solder promotes a strong, low impedance connection\u003cbr\u003e\u003cbr\u003e\n\nCustom-designed Feet\u003cbr\u003e\nAll 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.\nThe 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.\u003cbr\u003e\u003cbr\u003e\n\nExquisite, Large Level Meters Reflect the Dynamics in the Music\u003cbr\u003e\nThe M-5000 features large, high-precision meters on the front panel, enabling audiences to visualise the dynamics of the music.\nMeasuring 7 mm thick and made from Asahi glass, these quality meters only enhance the luxurious and exceptionally elegant aesthetic of the M-5000.\u003cbr\u003e\u003cbr\u003e\n\nExquisite, Large Level Meters Reflect the Dynamics in the Music\u003cbr\u003e\nThe M-5000 features large, high-precision meters on the front panel, enabling audiences to visualise the dynamics of the music.\nMeasuring 7 mm thick and made from Asahi glass, these quality meters only enhance the luxurious and exceptionally elegant aesthetic of the M-5000.\u003cbr\u003e\u003cbr\u003e\n\nTechnical Specifications:- \u003cbr\u003e\u003cbr\u003e\n\nAudio Specifications:\u003cbr\u003e\u003cbr\u003e\n\nInput Terminal:\nRCA: 1, BAL: 1, TRIGGER IN: 1 \u003cbr\u003e\n\nOutput Terminal:\nTRIGGER OUT: 1 \u003cbr\u003e\n\nRated Output Power:\n100 W + 100 W (8 ohm, 20 Hz-20 kHz, 0.07% THD, 2-ch driven), 200 W + 200 W (4 ohm, 20 Hz-20 kHz, 0.07% THD, 2-ch driven), 400 W (8 ohm, 20 Hz-20 kHz, 0.07% THD, Monaural driven) \u003cbr\u003e\n\nDynamic Power Per Channel:\n[IHF] 125 W + 125 W (8 ohm), 170 W + 170 W (6 ohm), 250 W + 250 W (4 ohm), 500 W + 500 W (2 ohm) \u003cbr\u003e\n\nDynamic Headroom:\n0.97 dB (8 ohm)\u003cbr\u003e \n\nMaximum Output Power:\n220 W + 220 W (4 ohm, 1 kHz, 0.7% THD) \u003cbr\u003e\n\nIEC Output Power:\n125 W + 125 W (8 ohm, 1 kHz, 0.02% THD)\u003cbr\u003e \n\nMaximum Effective Output Power:\n[JEITA, 1kHz, 10% THD]135 W + 135 W (8 ohm), 270 W + 270 W (4 ohm) \u003cbr\u003e\n\nPower Bandwidth:\n10 Hz-50 kHz (8 ohm, 0.1% THD, 45 W) \u003cbr\u003e\n\nDamping Factor:\n300 or higher (8 ohm, 1 kHz)\u003cbr\u003e \n\nInput Sensitivity \/ Input Impedance:\n(BAL) 2.0 Vrms \/ 47 kohm, (LINE) 1.0 Vrms \/ 47 kohm [1 kHz 100 W \/ 8 ohm conversion] \u003cbr\u003e\n\nMaximum Input Signal Voltage:\n(BAL) 2.20 Vrms [1 kHz, 0.5% THD], (LINE) 1.10 Vrms [1 kHz, 0.5% THD]\u003cbr\u003e \n\nFrequency Response:\n+0 dB \/ -3 dB (5 Hz-100 kHz), +0 dB \/ -0.3 dB (20 Hz-20 kHz) \u003cbr\u003e\n\nTotal Harmonic Distortion Plus Noise:\n2ch driven: 0.035% (LINE [BAL] to SP Out, 20 Hz-20 kHz, 50 W, 8 ohms), Monaural driven: 0.05% (LINE [BAL] to SP Out, 20 Hz-20 kHz, 200 W, 8 ohms) \u003cbr\u003e\n\nChannnel Separation:\n90 dB or higher (1 kHz, Input 1.0 kohm Terminated), 70 dB or higher (10 kHz, Input 1.0 kohm Terminated) \u003cbr\u003e\n\nSignal-to-Noise Ratio:\n[IHF-A network, Input 1 kohm shorted] 110 dB\u003cbr\u003e \n\nResidual Noise:\n[IHF-A network] (BAL) 40 uVrms, (LINE) 50 uVrms \u003cbr\u003e\n\nMeter Class:\nThe 2.5th class\u003cbr\u003e\u003cbr\u003e \n\nGeneral:-\u003cbr\u003e\u003cbr\u003e\n\nPower Consumption:\n400 W \u003cbr\u003e\n\nStandby Power Consumption:\nOff Mode: 0.1 W, Standby Mode: 0.2 W \u003cbr\u003e\n\nMaximum Power Consumption:\n800 W \u003cbr\u003e\n\nPower Management (Auto Power Standby):\nYes \u003cbr\u003e\n\nDimension (W×H×D):\n435 x 180 x 464 mm; 17-1\/8” x 7-1\/8” x 18-1\/4” \u003cbr\u003e\n\nWeight:\n26.9 kg; 59.3 lbs. \n\n","brand":"Yamaha","offers":[{"title":"Silver","offer_id":57414945866060,"sku":"YAMAHAM5000-S","price":5416.67,"currency_code":"GBP","in_stock":true},{"title":"Black","offer_id":57423812657484,"sku":"YAMAHAM5000-B","price":5416.67,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/Yamaha-M-5000-Silver.jpg?v=1777552572","url":"https:\/\/www.stoneaudio.co.uk\/products\/yamaha-m-5000-m5000-power-amplifier","provider":"Stone Audio","version":"1.0","type":"link"}
