Its fully analog amplifier design uses circuitry derived from Musical Fidelity’s TITAN power amplifier, with a low-distortion output stage arranged to avoid crossover artifacts and preserve control into demanding loudspeaker loads.\u003c\/p\u003e\n\u003cp\u003eThe M6xi delivers 220 W per channel into 8 ohms and 320 W per channel into 4 ohms, with substantial current capability and power reserves for wide dynamic range. Its PCB layout is designed to reduce circuit imbalances that would otherwise require corrective feedback, while the oversized encapsulated toroidal transformer and analog power supplies help reduce high-frequency noise and electromagnetic interference.\u003c\/p\u003e\n\u003cp\u003eConnectivity has been updated for modern systems, with HDMI eARC, coaxial, optical, and USB-C digital inputs, plus a balanced XLR input, 4 line-level RCA inputs, and an upgraded MM\/MC phonostage. A home-theater bypass input allows the M6xi to serve as the front left\/right amplifier in a multichannel system, while preamp outputs support bi-amping or active subwoofer integration.\u003c\/p\u003e\n\u003ch4\u003eFully Discrete Power Amplifier\u003c\/h4\u003e\n\u003cp\u003eThe M6xi is configured as 2 independent monobloc power amplifiers with a separate preamp stage, effectively combining a preamp and 2 power amps in one chassis. The amplifier stage uses Musical Fidelity’s classic low-distortion output topology and incorporates technology from the company’s TITAN amplifier platform.\u003c\/p\u003e\n\u003cp\u003ePower delivery is central to the design. The M6xi provides 220 Wpc into 8 ohms, 320 Wpc into 4 ohms, and 45 amps peak-to-peak current, giving it the headroom and control needed for difficult speaker loads and low-impedance dips.\u003c\/p\u003e\n\u003ch4\u003eModern Inputs and System Integration\u003c\/h4\u003e\n\u003cp\u003eThe M6xi adds HDMI eARC for TV and home-theater use, along with coaxial, optical, and USB-C digital inputs supporting up to 24 bit\/192 kHz resolution. RS232 control allows integration into custom-installed systems, and a 5 V\/2 A USB-A power output provides a clean power source for compatible external streamers.\u003c\/p\u003e\n\u003cp\u003eThe home-theater bypass input bypasses the preamp stage, allowing the M6xi to operate as a high-performance stereo power amplifier for the front left and right channels in a multichannel system. Fixed line outputs and variable preamp outputs provide additional flexibility for headphone amplifiers, external power amps, or active subwoofers.\u003c\/p\u003e\n\u003ch4\u003ePhonostage and Digital Separation\u003c\/h4\u003e\n\u003cp\u003eThe built-in MM\/MC phonostage has been upgraded with improved PCB layout, isolation, and shielding to reduce noise and distortion. The transformer and power supply PCB are encapsulated in a metal enclosure to reduce electromagnetic interference throughout the amplifier, with particular benefit to the high-gain phonostage circuitry.\u003c\/p\u003e\n\u003cp\u003eDigital and analog sections are physically separated on dedicated PCBs, with the digital and ARC boards using their own linear power supply. This separation is designed to reduce RF interference and protect the sensitive analog signal path.\u003c\/p\u003e\n\u003ch4\u003eBuild Quality\u003c\/h4\u003e\n\u003cp\u003eThe M6xi’s mechanical construction follows Musical Fidelity’s traditional all-metal approach, with heavy front and side panels milled from extruded aluminum profiles. The rigid aluminum casework helps reduce the effects of vibration while also acting as a shield against electromagnetic interference.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003ePower Output (8 ohm, 4 ohm):\u003c\/strong\u003e 220 W, 320 W\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eContinuous Power (8 ohm, 4 ohm, 20 Hz–20 kHz, 0.09% THD):\u003c\/strong\u003e 210 W, 300 W\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePeak Power (8 ohm, 4 ohm):\u003c\/strong\u003e 280 W, 450 W\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOutput Voltage:\u003c\/strong\u003e 43 V RMS, 20 Hz–20 kHz at onset of clipping\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePeak-to-Peak Voltage:\u003c\/strong\u003e 121 V\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePeak-to-Peak Current:\u003c\/strong\u003e 45 A\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDamping Factor:\u003c\/strong\u003e 49 into 8 ohms\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOutput Devices:\u003c\/strong\u003e 2 pairs per channel\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLine Input THD+N:\u003c\/strong\u003e \u0026lt;0.007% typical, 20 Hz–20 kHz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSignal-to-Noise Ratio:\u003c\/strong\u003e \u0026gt;107 dB, A-weighted\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLine Input Impedance:\u003c\/strong\u003e 40 kΩ\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e +0, –0.1 dB, 10 Hz–20 kHz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAnalog Inputs:\u003c\/strong\u003e 4 x stereo RCA line-level, 1 x stereo balanced XLR, 1 x MM\/MC phono\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDigital Inputs:\u003c\/strong\u003e 1 x HDMI eARC, 1 x coaxial, 1 x optical, 1 x USB-C, up to 24 bit\/192 kHz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAnalog Outputs:\u003c\/strong\u003e 1 x stereo RCA fixed line output, 1 x stereo RCA preamp output\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpeaker Outputs:\u003c\/strong\u003e 2 pairs 4 mm banana\/binding posts\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eControl:\u003c\/strong\u003e RS232 D-sub connector\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUSB Power Output:\u003c\/strong\u003e 5 V\/2 A USB-A\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePhono Sensitivity (MM, MC):\u003c\/strong\u003e 3 mV, 0.4 mV\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePhono Gain (MM, MC):\u003c\/strong\u003e 40 dB, 60 dB\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePhono Signal-to-Noise Ratio:\u003c\/strong\u003e \u0026gt;87 dB, A-weighted\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePhono Input Capacitance:\u003c\/strong\u003e 220 pF\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePhono Input Impedance (MM, MC):\u003c\/strong\u003e 50 kΩ, 1 kΩ\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePhono Frequency Response:\u003c\/strong\u003e RIAA\/IEC ±0.4 dB, 20 Hz–20 kHz\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower Requirement:\u003c\/strong\u003e 115\/230 V AC, 50\/60 Hz, factory pre-set\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower Consumption:\u003c\/strong\u003e 680 W maximum\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions (WHD):\u003c\/strong\u003e 17.3\" x 4.9\" x 15.7\" (440 x 125 x 400 mm)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 40.8 lb.
