Musical Fidelity M6xi Integrated Amplifier – High-Power Audiophile Performance with Modern Connectivity The Musical Fidelity M6xi integrated amplifier is engineered for audiophiles who demand uncompromising power, precision, and musical realism. Building on the success of the acclaimed M6 series, the M6xi combines advanced TITAN-derived amplifier technology with modern connectivity, delivering exceptional performance for both analogue and digital audio systems. TITAN-Derived Amplifier Design for Superior Sound At the heart of the M6xi is a fully discrete dual mono-block amplifier configuration inspired by Musical Fidelity’s flagship TITAN power amplifier. This advanced topology ensures exceptional channel separation, ultra-low distortion, and remarkable sonic accuracy. The low-distortion Darlington output stage eliminates crossover artefacts, preserving natural detail and tonal balance across the entire frequency range. High Power Output with Exceptional Control With 220W per channel into 8 ohms and 320W into 4 ohms, the M6xi offers immense power reserves and outstanding current delivery. This allows it to effortlessly drive demanding loudspeakers while maintaining control, clarity, and dynamic precision. Its high headroom ensures accurate peak performance, making it ideal for both high-volume listening and subtle, detailed playback. Precision Analogue Preamplifier Stage The M6xi features a fully analogue, low-noise preamplifier designed for maximum signal integrity. A premium Burr-Brown stepped attenuator provides precise volume control and excellent channel matching, resulting in stable stereo imaging and a refined soundstage. This ensures consistent performance across all listening levels, from quiet background music to full-scale dynamics. Advanced Connectivity for Modern Hi-Fi Systems Designed to integrate seamlessly into contemporary setups, the M6xi offers a wide range of connectivity options: HDMI eARC for TV and home theatre integration USB-C input supporting high-resolution audio (24-bit/192kHz) Optical and coaxial digital inputs Balanced XLR and RCA analogue inputs MM/MC phono stage for vinyl playback RS232 for custom installation systems USB-A power output for external streamers These features make the M6xi a versatile hub for both digital streaming and traditional hi-fi sources. Enhanced Phono Stage for Vinyl Playback The upgraded MM/MC phono stage features improved shielding and optimised circuitry, delivering lower noise and distortion. This allows vinyl enthusiasts to experience greater warmth, detail, and dynamic range from their records. Robust Build Quality and Premium Design Constructed with a solid aluminium chassis and precision-milled panels, the M6xi offers excellent resistance to vibration and electromagnetic interference. Its heavy-duty build ensures long-term reliability while maintaining the clean, elegant aesthetic expected from high-end audio equipment.
