The B1xi is the entry point into Musical Fidelity's xi range, a compact integrated amplifier that keeps the essentials and leaves out the excess. It runs a Class A/B power stage rated at 60 watts per channel into 8 ohms, paired with a low-noise preamp and a motor-driven analog volume control. That combination gives it clean, dynamic sound with enough power for most bookshelf and floorstanding speakers in a small to medium room.
Despite the modest size, the connectivity is up to date. There is a built-in moving magnet phono stage for a turntable, three RCA line inputs, and a digital section with optical, coaxial and ARC inputs handling up to 24 bit/192 kHz, plus Bluetooth 5.1 for wireless streaming. A preamp output allows bi-amping or adding an external power amplifier later. For a listener putting together a first proper hi-fi system around a turntable or a television, the B1xi covers analog and digital sources in one small box.

Why Consider the Musical Fidelity B1xi
A lot of first-time buyers end up with either a cheap all-in-one that they outgrow quickly, or an amplifier so large it does not suit the room. The B1xi sits in the useful middle. It is a real Musical Fidelity integrated amplifier with the phono stage, digital inputs and Bluetooth a modern system needs, in a chassis small enough for a compact shelf or desk. The moving magnet phono stage means a turntable plugs straight in, the ARC input lets it handle a television, and the preamp output leaves a clear upgrade path if you later want to add a power amplifier. It is the sensible starting point for someone building a proper system without overspending on the first box.
Ideal For
- First-time hi-fi buyers building a compact system
- Small to medium rooms where a full-size amplifier is too much
- Turntable owners using moving magnet or high-output MC cartridges
- Desktops and living rooms combining vinyl, streaming and TV
- Listeners who want Bluetooth alongside wired sources
- Buyers wanting a Musical Fidelity amplifier at an accessible price
