Musical Fidelity M6si Integrated Amplifier, Black Overview
The Musical Fidelity M6si is a high-performance integrated amplifier, designed with two independent mono power amps and a separate preamp inside a single chassis. Naturally, this layout gives you performance more akin to a full separates system, with pristine channel separation, greater dynamic range, and improved overall clarity. This makes it the perfect final upgrade to high-end home audio. Thanks to its dual monoblock design, the M6si is also capable of up to 220w per channel, comfortably driving even demanding sound systems.
To ensure compatibility with a range of high-fidelity equipment, you get four RCA line-level inputs, a balanced XLR, and a USB-B input that supports high-resolution playback up to 24-bit/96kHz. There's also a phono stage with MM/MC support, so you can connect a turntable directly without needing an extra preamp. Whether you're listening to vinyl, streaming from your computer, or running a full hi-fi setup, the M6si handles it all with power and poise.

Full Description
View Full DescriptionEffortless Power and Control
With 220W per channel into 8 ohms (400W into 4 ohms), the M6si delivers high-current output that controls speakers with authority. Its class A/B amplifier stage is designed for stability under load, ensuring dynamics remain intact even with inefficient or large floorstanders. Total harmonic distortion is exceptionally low at less than 0.007 (20Hz–20kHz), meaning the sound stays clean and composed across the spectrum. Whether reproducing subtle acoustic detail or wide-scale orchestral peaks, the M6si delivers power that feels expansive, balanced and built for long listening sessions.
Engineered Like Separate Components
Internally, the M6si is split into three sections: a preamp and two completely independent monobloc power amplifiers. Each power stage has its own dedicated heatsinks, power supply and layout, minimising crosstalk and preserving signal purity. Channel separation is excellent at over 82dB at 1kHz, and frequency response remains flat from 10Hz to 50kHz. This approach delivers the imaging and clarity you’d expect from separate boxes, but with the practicality of an integrated amp. It’s a technical design focused on reducing interference and revealing more musical information.
Versatile Connectivity for Every Setup
The M6si supports a wide range of source devices through its generous I/O options. Analogue inputs include four RCA line-level, one balanced XLR and a switchable MM/MC phono stage with accurate RIAA equalisation. Digital users can connect via asynchronous USB (24-bit/96kHz) for computer-based playback. A fixed pre-out and home theatre bypass add further flexibility for system expansion. Signal-to-noise ratio is 107dB (line) and 90dB (phono), ensuring low background noise and full-resolution playback from vinyl, streaming or CD. It’s a fully equipped amplifier built to grow with your system.
