M6si – Overview

At Musical Fidelity, we regard the M6si as a flagship product. The M6si provides such outstanding performance, features, 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 preamp. In essence, it is a preamp with 2 monobloc power amps that happen to share the same chassis.

The M6si delivers 220 watts per channel. It boasts very low distortion, an exceptional signal-to-noise ratio, and an extremely flat frequency response. Its inputs include phono (MM/MC), 4 line-level, 1 balanced XLR, and 1 USB ‘B’ for asynchronous data stream up to 24-bit/96kHz.

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

In use, it is challenging to discern 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.
