The M6si500 is a high-performance, high-powered super integrated amplifier. Building on the legacy of the Musical Fidelity A1000, which initiated the super integrated amplifier genre 25 years ago, the M6si500 continues to refine this concept.

Performance and Power

The M6si500 offers an impressive 500 watts per channel, delivering exceptional load driving ability, outstanding technical performance, and robust build quality. This remarkable amplifier is capable of driving any loudspeaker to its maximum potential with ease.

Inputs and Outputs

The M6si500 features five inputs: four line-level inputs and one balanced XLR input. It also includes preamp and fixed line outputs, as well as a home theatre bypass option.

Listening Experience

Listening to the M6si500 is a sensuous experience. It produces an effortless, silky sound with vast dynamics and a broad, deep soundstage. Even if you are not in the market for an amplifier at this level, experiencing the M6si500 will help you understand the enthusiasm it generates.

Build Quality and Design

The M6si500 boasts a high-quality metal construction, offering both distinctive style and a solid performance platform. The front panel is a bespoke, fine-line extrusion of military-grade aluminum, while the custom-made heatsinks provide outstanding dissipation and a fine finish.

Engineered as a genuine dual-mono design, each power amp section has its own heat sink and separate transformer, while the preamp has its own power-supply winding. The five input sockets are directly connected to the main preamp circuit board, ensuring an ultra-short signal path and ultra-low impedance from the source to the amplifier.

Each channel features 12 large bipolar transistors, providing 200 amps peak-to-peak performance. A precision digital volume control, utilizing laser-trimmed substrate resistors, ensures perfect tracking even at very low listening levels.

Technical Performance

The M6si500 delivers stellar technical performance, with remarkably low distortion levels (around 0.008% at 1kHz, 0.015% at 20kHz, and only slightly rising to 0.02% at ultra-high frequencies of 30-50kHz). The signal-to-noise ratio is also minimal, ensuring exceptional linearity and consistency.
