At Musical Fidelity we think of the M6si as being a destination product. 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 pre amp with 2 monobloc power amps that just happen to share the same casework.

The M6si has 220wpc. It has very low distortion, outstanding noise ratio and 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.
