M2si - Overview

The M2si integrated amplifier takes our peerless premium-amp experience and applies it to a more affordable price point. It boasts trickle-down technology from our mighty and legendary Titan flagship, plus other high-end touches such as solid metal controls. The M2si delivers 72 watts per channel into 8 ohms and 137 watts into 4 ohms. This means the M2si will drive a wide range of speakers, even power-hungry models.

Further flexibility is provided by the M2si's excellent connectivity, which includes six line-level inputs and switchable home-theatre throughput. It features a Class A preamp stage with its own, independant power supply, coupled with a discrete pair of power amps. In effect, this means the M2si offers the performance benefits of a pre/power configuration with the compact convenience of a one-box design.

Its performance is rock-solid, it's sonically well-rounded and it's comfortable with a wide array of speakers. And it's all served up in an elegant, no-nonsense package.
