M2si Stream - Overview

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.

Precision Matched Preamp and PRE/POWER Configuration

The 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.

The Musical Fidelity Design-Philosophy

Further 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.

Redefining The Amplifier

With 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 puristic 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 puristic audiophile integrated amplifier for a lifetime, solely designed for the maximum of musical fidelity.

Musical Fidelity NOW streams

We’ve seen a surge in offerings from HiFi companies with all-in-one solutions, sometimes with big displays on top. Unfortunately, such developments mean that sound quality suffers. At Musical Fidelity, we acknowledge that any WiFi or BT circuitry generates a substantial amount of RF pollution and distorts analogue amp circuitry when incorporated into integrated, one-box solutions.

Musical Fidelity stands for sound quality and robust design that lasts for decades

We INVEST our money and resources in top-tier hardware and the pursuit of optimal music reproduction.

• Robust mechanics - Discrete circuits - Huge transformers - Class A/B amps.
• No HF and RF distortion.

We aim to have the best hardware and sound quality in every price range and make true high-end affordable.

We are partnering with one of the best STREAMING SPECIALISTS - the US Californian high-tech company LINKPLAY.

The M2si Stream includes a free WiiM Mini

The separate box and separate power supply ensure that we reduce RF and HF radiation and we can keep our analog amplifier technology as good as it is. LINKPLAY offers state-of-the-art technology, seamlessly compatible with any contemporary streaming service on the market, all navigable through an INTUITIVE and user-friendly APP. Moreover, their consistent maintenance and software updates ensure an optimal user experience.
