MUSICAL FIDELITY M3si

Pre owned. In excellent condition, showing no visible signs of wear. Comes with remote control and original packaging.

The Musical Fidelity M3si is a modern interpretation of British audio tradition, an integrated amplifier that naturally combines the warm, musical character typical of the brand with contemporary technological needs. It is designed to deliver the high-end experience of the M series in a more accessible form, without compromising the build quality and sonic personality that have made the London-based company renowned. The amplifier features an asynchronous 24-bit/96 kHz USB DAC and a carefully designed MM phono stage, expanding listening options and providing top-level performance from the first use. Inside, a completely redesigned power section comes to life, where Sanken transistors and enhanced filtering work together to deliver 85 watts per channel with generous current reserves and solid, consistent control even on demanding speakers. The large toroidal transformer provides clean energy, while the layout of the analog circuits preserves signal purity by keeping sensitive areas isolated.

In listening, the M3si delivers a balanced and natural timbre, with refined highs that never fatigue and a full, well-defined mid-bass range that remains dynamically controlled. The digital section functions as a true musical hub, thanks to the Texas Instruments chip, which offers detailed and airy playback capable of opening the soundstage in both depth and width. The integrated phono stage also impresses with its quietness and musicality, enhancing MM cartridges with full, precise sound free from unwanted coloration. The amplifier is extremely versatile and easy to integrate into any system: it accommodates line, phono, USB inputs and a home theater bypass, while the speaker terminals support all types of connections. Its compact dimensions and solid construction facilitate placement, and the remote control ensures immediate and intuitive operation. The aesthetic design follows Musical Fidelity’s historic philosophy, featuring a sober and elegant look that prioritizes functionality and blends discreetly into any environment. The M3si thus presents itself as an amplifier that honors British tradition while updating it with contemporary sensitivity, offering a convincing balance of musicality, power, and technology.
