Configured as 2 independent monobloc power amps with a separate preamp stage, it draws technology from Musical Fidelity's 1kW TITAN power amplifier and delivers 220W per channel into 8 ohms and 320W into 4 ohms.

The main transformer and power supply PCB are encapsulated within a metal enclosure, reducing electromagnetic interference throughout the amplifier — a benefit felt especially in the refined phono stage. Improved components and increased output capability give the M6xi greater authority and control over demanding loudspeakers while preserving the Musical Fidelity house sound.\u003c\/p\u003e\n\n\u003ch2\u003ePreamplifier\u003c\/h2\u003e\n\u003cp\u003eThe fully analogue preamplifier stage is built for signal integrity across the entire dynamic range, using a low-noise circuit design. Volume control uses a Burr-Brown stepped attenuator rather than a conventional potentiometer, offering more precise channel matching for balanced stereo imaging and stable soundstage placement at any listening level.\u003c\/p\u003e\n\n\u003ch2\u003ePhono Stage\u003c\/h2\u003e\n\u003cp\u003eThe redesigned MM\/MC phono stage uses an improved PCB layout with enhanced isolation and shielding to reduce noise and distortion. Because phono circuitry works with amplification factors up to 1,000, shielding it from external interference is especially critical — the encapsulated transformer and power supply position were tuned specifically to protect this high-gain stage.\u003c\/p\u003e\n\n\u003ch2\u003eConnectivity\u003c\/h2\u003e\n\u003cp\u003eM6xi includes 4x RCA inputs, a balanced XLR input, and an MM\/MC phono input that's been upgraded compared to the M6si. A home theater bypass input bypasses the preamp stage entirely, letting the M6xi act as a high-performance stereo power amp for the front left\/right channels in a multichannel system. New optical, coaxial, and HDMI eARC inputs add digital connectivity, alongside a USB-C input supporting up to 24-bit\/192kHz, and an RS232 interface for custom-install system control. A 5V\/2A USB-A power output, with its own separate transformer winding and linear supply, powers an external streamer and doubles as a power supply upgrade for it. The variable pre-out connects to an external power amp like the M6sPRX for bi-amping or to an active subwoofer, while the fixed line output is best suited to a headphone amplifier.\u003c\/p\u003e\n\n\u003ch2\u003eReviews\u003c\/h2\u003e\n\u003cblockquote\u003e\"The M6xi is a monster. A big amplifier sound that I could listen to all day. You can turn the volume up and up and up and the sound from the speakers grows and gets more dynamic.
