Our take on the Musical Fidelity M6si500 Integrated Amplifier

The M6si500 is Musical Fidelity's super integrated amplifier, rated at 500 watts per channel into 8 ohms. Inside it is built as a separate preamp plus two independent monobloc power amps, so it behaves like a separates system in one chassis. It has five inputs, including balanced XLR, plus preamp and fixed line outputs and a home theater bypass. It suits owners of large or hard-to-drive floorstanding speakers who want one box with huge power and headroom, and it competes with high-power integrateds and pre/power separates at the same level.

About the Musical Fidelity M6si500 Integrated Amplifier

The M6si500 is a super integrated amplifier that delivers 500 watts per channel into 8 ohms. It has five inputs: four line inputs and one balanced XLR. It also has preamp and fixed line outputs and a home theater bypass.

Internally, it is a separate preamp with two independent monobloc power amps. The design is dual-mono: each power amp section has its own heat sink and separate transformer, and the preamp has its own power-supply winding. Each channel uses 12 bipolar transistors and can supply 200 amps peak-to-peak.

The front panel is a fine-line extrusion of military-grade aluminum. The heatsinks are custom-made for heat dissipation. The five input sockets connect directly to the main preamp circuit board instead of through wires, which keeps the signal path short. A digital volume control with laser-trimmed substrate resistors keeps channel tracking accurate at very low listening levels.

Questions and answers

How much power does the M6si500 deliver?
It is rated at 500 watts per channel into 8 ohms. Musical Fidelity says it will drive any loudspeaker with ease.
What inputs does it have?
Four line inputs (CD, tuner, aux/HT, tape) and one balanced XLR input. It also has preamp and fixed line outputs and a home theater bypass.
Does it have a built-in DAC or phono stage?
No. It is a pure analog integrated amplifier, so you need a separate DAC for digital sources and a separate phono stage for a turntable.
How is it built inside?
It is a separate preamp with two independent monobloc power amps in one chassis, effectively a separates system in a box.
Will it drive difficult speakers?
Yes. Its high power and load-driving ability are its main selling points, and owners report it handles demanding floorstanders without strain.
Can I use it in a home theater system?
Yes. The home theater bypass lets it power the front speakers from an AV processor while keeping its own preamp out of the path.
Where is the Musical Fidelity M6si500 Integrated Amplifier cheapest?
At Audio Emotion Limited, for $5,365.05, as of our latest check.
