The M2si integrated amplifier brings premium-amp technology to a more affordable price point. Drawing from the design philosophy of the TITAN flagship, and featuring high-end elements like robust metal controls, an extruded aluminum front panel, and an all-metal chassis, the M2si offers discerning audiophiles an unadulterated high-end amplifier experience.

Fully Discrete Power Amplifier

The M2si delivers 72 watts per channel into 8 ohms and 137 watts into 4 ohms, making it capable of driving a wide range of speakers, including power-hungry models. The fully discrete power amplifier, along with its dedicated power supply and generously proportioned toroidal transformer, ensures ample reserves for peak delivery and a wide dynamic range. It handles low impedance dips gracefully, and its judiciously rated output devices won’t falter under any load.

Precision Matched Preamp and PRE/POWER Configuration

The low-noise preamp has its own independent power supply, offering the performance benefits of a pre/power configuration with the compact convenience of a one-box design. For optimal low-channel volume matching, a high-quality Burr-Brown stepped attenuator is used, providing performance far superior to conventional potentiometer designs.

The Musical Fidelity Design Philosophy

The M2si offers flexibility with six line-level inputs and switchable home-theatre throughput. It purposefully excludes a phono input and digital high-frequency DAC circuitry to maintain unadulterated sound quality. Introducing digital high-frequency modules would compromise the nuanced performance of the analog pre and power amplifiers, and the substantial transformer and power amp circuitry could interfere with delicate phono signals.

Redefining The Amplifier

The M2si aims to distill the expertise and design principles honed in high-end amplifiers into an unbeatable package at this price point. By focusing on a puristic and audiophile-oriented amplifier design, the M2si offers a true Musical Fidelity experience, delivering what audiophiles desire most: an affordable, high-quality integrated amplifier designed for lifelong musical fidelity.



  • High-end circuitry inspired by TITAN
  • Fully discrete transistor-based Class A/B power amp design
  • Drives power-hungry speakers with ease and handles low impedance dips gracefully
  • 72W/8 Ohm & 137W/4 Ohm output power
  • Extreme power reserves for proper peak power delivery and wide dynamic range
