Building on the outstanding success of its predecessor, the M5si, the M5xi is a major reinvention of the M5 formula. The preamp, poweramp, digital and phono sections are completely new and now much closer to our legendary TITAN power amp topology. In fact, the M5xi now commands the same topology as previously used in the M6si, including all the improvements for the newly released M6xi update, just tuned for less power output. This makes the TITAN formula accessible at a new price-point as Musical Fidelity pushes to make true high-end amplifiers as affordable as never before.
Modern systems demand modern connectivity. The M5xi now features HDMI eARC, allowing effortless integration with TVs and home theatre 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 M5xi now includes RS232 integration, making it ideal for custom installations and sophisticated home audio systems.
