{"product_id":"musical-fidelity-m2si-integrated-amplifier","title":"Musical Fidelity M2Si Integrated Amplifier","description":"\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eFully Discrete Power Amplifier\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ccenter\u003e\u003cimg src=\"https:\/\/www.musicalfidelity.com\/uploads\/images\/productpage\/MF-M2si-internals.jpg\"\u003e\u003c\/center\u003e\n\u003ch3\u003ePrecision Matched Preamp and PRE\/POWER Configuration\u003c\/h3\u003e\n\u003cp\u003eThe low noise preamp has its own, independent power supply. In effect, this means the M2si offers the performance benefits of a pre\/power configuration with the compact convenience of a one-box design. For best low channel volume matching we employ a high quality Burr-Brown stepped attenuator delivering performance way above that of conventional potentiometer designs.\u003c\/p\u003e\n\u003ch3\u003eThe Musical Fidelity Design-Philosophy\u003c\/h3\u003e\n\u003cp\u003eFurther flexibility is provided by the M2si‘s carefully considered connectivity, which includes six line-level inputs and switchable home-theatre throughput. We have purposefully decided against a phono input or any digital high-frequency and DAC circuitry. The M2si remains committed to unadulterated sound quality over extraneous features. The introduction of digital high-frequency modules would be at odds with the nuanced performance of the analogue pre and power amplifiers, and the substantial transformer and power amp circuitry could introduce interference to delicate phono signals.\u003c\/p\u003e\n\u003ch3\u003eRedefining The Amplifier\u003c\/h3\u003e\n\u003cp\u003eWith the M2si, our aim was to distill the expertise and design principles honed through our high-end amplifiers, creating an unbeatable package in this price point. Rather than burdening the analog amplifier‘s performance with superfluous features, we opted for a pure and audiophile-oriented amplifier design that would elicit envy from owners of more costly, feature-loaded integrated amplifiers. With a true Musical Fidelity amplifier, you receive precisely what you desire. An affordable and pure audiophile integrated amplifier for a lifetime, solely designed for the maximum of musical fidelity.\u003c\/p\u003e\n\u003ch3\u003eM2si In Brief\u003c\/h3\u003e\n\u003ch3\u003eAmplifier\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-end circuitry inspired by TITAN\u003c\/li\u003e\n\u003cli\u003eFully discrete transistor based Class A\/B power amp design\u003c\/li\u003e\n\u003cli\u003eDrives power hungry speakers with ease and gracefully manages low impedance dips\u003c\/li\u003e\n\u003cli\u003e72W\/8 Ohm \u0026amp;
