Integrated amplifiers — Musical Fidelity M5xi

The M5xi is an integrated amplifier from Musical Fidelity, sitting above the M5SI with considerably greater output power and genuinely comprehensive dual-cartridge phono support. The M5xi brings Musical Fidelity's more accomplished current engineering to a complete integrated chassis.

Key specs that matter

Four single-ended inputs plus a dedicated phono input are provided. Input impedance is 40,000 ohms. The phono stage uses a genuinely sophisticated current-sensing design covering both 50,000 ohms MM and 1,000 ohms MC input impedance. Output power is 160W into 8 ohms, rising to 240W into 4 ohms - considerably more than the M5SI's 150W. Signal-to-noise ratio exceeds 105dB, with total harmonic distortion plus noise under an exceptionally low 0.009%. At 440 x 125 x 405mm and 15kg, the M5xi represents a genuinely more substantial commitment reflecting Musical Fidelity's more accomplished current engineering.

Sound and use context

Expect the musically engaging character Musical Fidelity's broader British catalogue is celebrated for, with the genuinely sophisticated dual-cartridge phono stage handling both moving-magnet and moving-coil cartridges without a separate step-up device.

Pairing

The current-sensing phono stage handles both moving-magnet and moving-coil cartridges directly without needing a separate step-up transformer.

Alternatives

Musical Fidelity's own M6SI offers a considerably more powerful alternative 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.
