With its refined build quality and powerful sound delivery, the M1xi embodies Musical Fidelity’s long-standing commitment to pure, engaging audio reproduction.

The Musical Fidelity M1xi Amplifier is available for demonstration in our Hull store by request.

Class A/B Power That Commands Any Speaker

At the core of the Musical Fidelity M1xi is a meticulously designed Class A/B amplifier circuit, capable of delivering 60 watts per channel into 8 ohms and up to 140 watts into 2 ohms. This allows the M1xi to drive a wide range of speakers effortlessly, maintaining control and musicality even at high output levels. Its combination of low distortion, high current capability, and wide dynamic range ensures that every note is presented with precision, warmth, and depth.

The amplifier’s sonic character is both revealing and natural, making it equally adept at handling delicate acoustic performances or full orchestral recordings. This power and poise make it an ideal centrepiece for any high-fidelity system.

Engineered for Audiophiles, Designed for Modern Living

The M1xi integrated amplifier has been created to accommodate modern listening habits without compromising on audio quality. It offers a wide selection of inputs to suit a variety of sources. Vinyl enthusiasts will appreciate the low-noise, high-gain MM phono stage, while digital listeners benefit from the built-in DAC, ensuring pristine conversion of digital audio signals.

The inclusion of HDMI ARC allows seamless integration with televisions for home entertainment use, while Bluetooth connectivity supports high-quality wireless streaming from smartphones, tablets, or computers. Additional features include RCA variable pre-outputs for connecting subwoofers or external power amplifiers, a USB-C power output for powering external streamers, and both front-mounted mini-jack and headphone outputs for private listening.

No Wi-Fi by Design: Longevity Over Compromise

Unlike many integrated amplifiers that include built-in Wi-Fi streaming, the Musical Fidelity M1xi deliberately omits it. This design choice prioritises audio performance, build quality, and longevity. All-in-one streaming amplifiers often require compromises in either sound quality or long-term reliability.

By keeping streaming hardware separate, the M1xi ensures compatibility with any future external streamer while maintaining the amplifier’s integrity and lifespan. This modular approach allows users to update their digital front-end as technologies evolve, while the amplifier remains a timeless, high-quality core of their audio system.

Dual Power Supply Architecture for Pristine Audio

The M1xi’s preamplifier stage features its own dedicated linear power supply, providing ultra-low noise and exceptional channel separation. This design effectively isolates the preamp and power amp sections, allowing them to operate as independent yet harmonised components. The result is a cleaner signal path and improved overall clarity.

Volume control is handled by a motor-driven analogue potentiometer, providing precise adjustment and maintaining signal purity. Together, these design features deliver a listening experience that feels dynamic, natural, and effortlessly controlled.

Premium Build, Inside and Out

Every detail of the Musical Fidelity M1xi amplifier reflects thoughtful engineering and craftsmanship. Its internal layout separates analogue and digital circuits onto discrete PCBs, each with its own linear power supply to reduce interference. The amplifier’s exterior is constructed from high-grade aluminium, with robust metal controls and an extruded front panel that conveys both durability and refinement.

The chassis design not only contributes to the amplifier’s elegant aesthetic but also serves a functional role in minimising vibration and maintaining signal integrity. The result is a component that looks as premium as it performs.

A True Hi-Fi Heart for Every System

The Musical Fidelity M1xi integrated amplifier is designed to serve as the central hub of any high-quality audio system. By blending analogue purity with digital versatility, it delivers an engaging and lifelike musical experience across all genres and formats. Whether connected to a turntable, CD player, or streaming source, the M1xi consistently reveals the depth, texture, and emotion of every recording.

Musical Fidelity’s dedication to timeless design ensures that the M1xi is not just an amplifier but a long-term investment in high-fidelity sound. Its combination of power, precision, and flexibility makes it an ideal choice for music lovers seeking a pure and lasting connection to their favourite recordings.
