Power with full control

The M5si is engineered with a focus on high current capacity and stable operation. The powerful power supply and efficient output stage give the amplifier the necessary resources to drive both compact monitor speakers and large floorstanding speakers with confident control.

The result is a dynamic and well-balanced presentation with a large soundstage, precise detail, and a solid bass foundation – even at higher volume levels.

Thoughtful internal design

Internally, the M5si is built with two independent power amplifier sections and a separate preamplifier assembled on a single circuit board. The dual mono-inspired design reduces internal interaction between channels and contributes to stable, precise, and well-defined stereo reproduction.

The technical design is based on many of the same principles used in the larger models from Musical Fidelity, ensuring high performance and long-lasting operation.

Ready for both vinyl and digital audio sources

The M5si is equipped with a built-in MM phono stage, allowing a turntable with an MM cartridge to be connected directly without the need for an external phono stage.

In addition, the amplifier is equipped with an asynchronous USB DAC for computer-based music playback as well as four analog line inputs, making it easy to bring together both classic and modern audio sources in one complete hi-fi system.

Built for many years of musical enjoyment

For decades, Musical Fidelity has been known for solid construction with powerful toroidal transformers and carefully selected components. The M5si continues this tradition with high build quality, a stable power supply, and a mechanical construction developed for many years of use.

This results in an integrated amplifier that delivers stable performance and musical enjoyment year after year.

A strong foundation in any hi-fi system

Musical Fidelity M5si combines high power, great flexibility, and well-balanced sound in one integrated amplifier. It fits naturally into both analog and digital hi-fi systems and is an obvious choice for music lovers who want a powerful stereo amplifier with plenty of headroom, high reliability, and the characteristic Musical Fidelity sound.
