Integrated amplifiers — Musical Fidelity M6SI500

The M6si500 is a powerful integrated amplifier with built-in phono stage from Musical Fidelity, built with a substantial 500W output into a serious mass. The M6si500 brings Musical Fidelity's considered engineering to a substantial integrated chassis.

Key specs that matter

One balanced XLR input and one single-ended input are provided, with a built-in phono stage. Output power is a substantial 500W into 8 ohms - an unusually high figure for a single-chassis integrated amplifier. Frequency response spans a wide 10Hz to 20,000Hz within plus-or-minus 3dB. Signal-to-noise ratio exceeds 100dB, with total harmonic distortion plus noise under 0.01%. At 440 x 160 x 460mm and 30kg, the M6si500's considerable weight reflects serious internal power-supply engineering needed to deliver its substantial output.

Sound and use context

Expect extraordinary dynamic authority reflecting the substantial 500W-into-8-ohms output, an unusually high figure for a single-chassis integrated design, with the built-in phono stage covering vinyl playback directly.

Pairing

The substantial 500W output handles even demanding, low-sensitivity loudspeakers with ease, and the built-in phono stage covers a turntable directly without needing a separate outboard unit.

Alternatives

Musical Fidelity's own broader amplifier catalogue offers alternatives with more modest power output within the same broader catalogue.
