The M2si integrated amplifier takes our premium-amp technology and applies it to a more affordable price point. Drawing upon the design philosophy and insights gleaned from our mighty TITAN flagship, along with the inclusion of high-end elements such as the robust metal controls, extruded aluminum front panel, and a chassis crafted entirely from metal, the M2si occupies an enviable position for discerning audiophiles seeking an unadulterated high-end amplifier.

Fully Discrete Power Amplifier
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. The fully discrete power amp, complemented by its dedicated power supply and generously proportioned toroidal transformer, guarantees reserves for proper peak delivery and a wide dynamic range. Power hungry and difficult speakers are driven with ease. Low impedance dips are managed gracefully and the judiciously rated output devices won?t faulter under any load.

Amplifier:

High-end circuitry inspired by TITAN

Fully discrete transistor based Class A/B power amp design

Drives power hungry speakers with ease and gracefully manages low impedance dips

72W/8 Ohm & 137W/4 Ohm output power

Extreme power reserves for proper peak power delivery and wide dynamic range

Pure sound quality instead of features:

- No digital circuitry: no digital high-frequency modules built in

- No phono stage: huge transformer and power amp circuitry will not interfere with low level phono signals

HT-input: bypassed preamp-stage allows connecting home-theater processors to use your M2si as ultimate L/R channel amp

Preamplifier:

Low noise design for best THD and signal integrity at low as well as high levels

High quality Burr-Brown stepped attenuator for better channel matching than conventional potentiometer designs

Pre Out for bi-amping with M6sPRX or active subwoofer connection

Power Supply:

Generously rated 280VA toroidal transformer

Independent power supplies for preamp and poweramp
