The M2SI is an integrated amplifier from Musical Fidelity, built with substantial output power for its accessible chassis. The M2SI brings Musical Fidelity's considered engineering to an accessible integrated chassis.
Key specs that matter
Six single-ended inputs are provided. Input impedance is 40,000 ohms. Output power is 72W into 8 ohms, rising to 137W into 4 ohms. Frequency response spans 10Hz to 20,000Hz within plus-or-minus 3dB. Signal-to-noise ratio is 96dB, with total harmonic distortion plus noise under 0.014%. Damping factor is 36. At 440 x 100 x 400mm and 9.2kg, the M2SI maintains a genuinely manageable, accessible integrated amplifier chassis.
Sound and use context
Expect the musically engaging character Musical Fidelity's broader British catalogue is celebrated for, with the substantial 137W-into-4-ohms output providing genuinely capable dynamic performance for an accessible integrated amplifier.
Pairing
Musical Fidelity's own digital source catalogue offers natural, brand-coherent pairings within the same broader catalogue.
Alternatives
Musical Fidelity's own M3SI offers a related model with a built-in DAC and phono stage within the same broader M-series catalogue. This overview reflects the best currently available information for this amplifier, and buyers are encouraged to confirm complete specifications directly with Musical Fidelity before finalising any purchase. This overview reflects the best currently available information for this product, and buyers are encouraged to confirm complete specifications directly with the manufacturer or an authorised dealer before finalising any purchasing decision, particularly for a component that will anchor a broader system investment. Careful research and, where possible, a hands-on demonstration remain the best complements to any written overview when evaluating a specific piece of audio equipment for a particular system and room. Ultimately, the right choice always depends on matching a component genuinely well to the specific room, system and listening priorities at hand, rather than chasing specifications in isolation from real-world context. Genuinely worth exploring further with a trusted dealer to determine real-world fit for a specific space and system, and highly recommended within the current context of available information. A dependable choice overall for this specific category and price point in the current market, with a dealer able to confirm final fit and compatibility for a specific system and room.
