Musical Fidelity M6SI - Integrated Amplifier

The Musical Fidelity M6si is a high-end stereo integrated amplifier designed for listeners who want serious power, pristine sound, and versatile functionality all in one box. Internally, it’s built like a dual-monobloc + preamp system: separate power amps for each channel plus a dedicated preamp stage. With 220 watts per channel into 8 ohms, low distortion, and a wide, flat frequency response, it's capable of driving demanding loudspeakers with ease. It includes a built-in phono stage (MM/MC), an asynchronous USB-B input (up to 24-bit/96 kHz) for digital sources, balanced XLR + multiple line inputs, and a preamp output. The build quality is solid, with heavy heat sinks, a robust chassis, and excellent component layout so that it remains quiet, stable, and capable even under challenging loads. Musical Fidelity+3

Description

The M6si is a new amplifier with incredible realism and emotional involvement.

The M6si offers such excellent performance, facilities, and power that, unless you are seeking the most exotic high-end sound quality, you would never need another amplifier. We believe it’s that good.

Internally, the M6si is configured as 2 independent monobloc power amps with a separate pre-amp. It is, in fact, a preamp with 2 monobloc power amps that just happen to share the same casework.

The M6si has 220wpc. It has very low distortion, an outstanding noise ratio, and an extremely flat frequency response. Its inputs are phono (MM/MC), 4 line level, 1 balanced XLR, and 1 USB ‘B’ up to 24bit 96kHz asynchronous.

The M6 combination of high power, high current, and extraordinary stability means that it can drive any loudspeaker with ease.

In use, it is hard to hear any practical difference between the M6si and other much more expensive amplifiers. In proper blind listening comparisons, the M6si performs incredibly well. If we sound rather enthusiastic, it’s because we are.

We love the M6si and hope that you do too.
