mf mxi internals large fullAt its core, the Musical Fidelity M8xi Integrated Amplifier is a marvel of engineering. Its fully dual-mono architecture separates the preamplifier and twin monobloc power amps within a single chassis, each with its own heatsink and oversized toroidal transformer. This design minimises interference, ensuring a soundstage that’s expansive, detailed, and utterly immersive. The preamp section, powered independently, sits close to the input sockets for short signal paths, reducing noise and preserving audio purity. With distortion levels below 0.005% and a signal-to-noise ratio exceeding 86dB, the M8xi delivers a crystalline, noise-free experience that lets you hear every breath, pluck, and drumbeat as intended. Add to that a built-in DAC handling PCM up to 24-bit/192kHz (via USB and coaxial), and you’ve got a versatile hub for both analogue and digital sources—perfect for modern hi-fi audio setups.

For the discerning listener, the Musical Fidelity M8xi Integrated Amplifier offers unmatched flexibility. Its rear panel is a treasure trove of connectivity: two balanced XLR inputs, four RCA line-level inputs (one switchable to home theatre bypass), and five digital inputs (two optical, two coaxial, and one USB-B). Dual preamp outputs (XLR and RCA) and digital outputs (optical and coaxial) make it a future-proof addition to any system. Whether you’re connecting a turntable via an external phono stage, streaming from a computer, or integrating it into a home cinema, this amplifier adapts effortlessly. Its high current output and bridged topology ensure unconditional stability, driving even the most demanding speakers with a tight, controlled bass and a shimmering top end that never fatigues.
