Musical Fidelity proudly introduces the M6xi, the newest high-end integrated amplifier in our acclaimed M6 line. Building on the outstanding success of its predecessor, the M6si, the M6xi continues the same proven formula: massive power, uncompromising engineering, and true high-end sound, now enhanced with modern connectivity and refined internal design.
Modern systems demand modern connectivity. The M6xi now features HDMI eARC, allowing effortless integration with TVs and home theater systems while delivering true high-end stereo performance. Alongside this, new coaxial and optical digital inputs expand connectivity for a wide range of digital sources, complementing the already established high-resolution USB input.
A completely new feature is the high-quality isolated USB power output. Designed as a dedicated, ultra-clean power supply, it allows you to power modern USB streamers directly from the amplifier. The result is simple system integration and a noticeable upgrade in performance for your favourite streaming source.
For professional installations and advanced system control, the M6xi now includes RS232 integration, making it ideal for custom installations and sophisticated home audio systems.
