Musical Fidelity B1xi Integrated Amplifier

Overview

The Musical Fidelity B1xi brings the brand's long standing British engineering philosophy into a compact and highly practical integrated amplifier. Built around a fully discrete transistor based Class A/B output stage, it delivers 60 watts into 8 ohms and 100 watts into 4 ohms, giving it the control and drive to bring a wide range of loudspeakers to life. This is the kind of everyday amplifier that focuses on musical honesty rather than gimmicks.

Connectivity is genuinely generous for a component of this size. You get three pairs of RCA line inputs and a dedicated moving magnet phono stage for turntable owners, plus a full set of digital inputs including optical, coaxial, ARC for televisions, and Bluetooth for casual streaming. That flexibility makes the B1xi a natural hub for a modern system that mixes vinyl, streaming, and TV audio in one place.

At All Elite Audio we appreciate how the B1xi carries the tonal character of larger Musical Fidelity amplifiers into a footprint that fits almost any shelf or rack. It is a no frills, well equipped design that pairs beautifully with efficient and precise loudspeakers, making it an easy recommendation for listeners building a serious system without unnecessary complexity.
