Musical Fidelity M2si Integrated Amplifier
The Musical Fidelity M2si is a purist integrated amplifier designed for listeners who prioritize musical fidelity over added features. Built around fully discrete analog circuitry, it applies the design principles of Musical Fidelity’s high-end amplifiers to a more accessible format while maintaining a strong focus on sound quality and long-term reliability.
With substantial power reserves and a carefully engineered power supply, the M2si is capable of driving a wide range of loudspeakers with control and stability. Its straightforward analog-only architecture avoids digital and phono circuitry to preserve signal purity throughout the amplification stages.
