One of the most important factors when deciding on an integrated amplifier is its power ratings and compatibility with your speaker's impedance requirements.The Musical Fidelity M2si is rated at 76 watts RMS into 8-ohms. Musical Fidelity provides this wattage at a THD (Total Harmonic Distortion) of 0.014% which is an important indicator of distortion at the given values (lower THD is better).
Here are the main highlights of its performance specs:
- 76 watts into 8-ohms (10 Hz-20 kHz) at 0.014%
- 137 watts into 4-ohms
- 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)
- 96dB Signal to Noise Ratio

Which speakers suit the Musical Fidelity M2si?
76 W into 8 ohms, 135 W into 4, rated down to 4 ohms.
We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
When pairing the Musical Fidelity M2si with a passive Bookshelf (Stand mount) or Passive Floor Standing (Tower) speaker, you have to check if their Max Power Range is below the max wattage of the amp for the given impedance levels.
Operating your amp outside of this max range may damage the speakers.
