Musical Fidelity B1xi Integrated Amplifier
The B1xi brings Musical Fidelity’s long-standing amplifier know-how to listeners who want power, clarity and convenience in a single unit. Designed with a responsive Class A/B topology that delivers 60 watts per channel into 8 ohms, it supplies generous drive for bookshelf speakers and floorstanders alike. HDMI licensing and HDMI ARC support let you link the B1xi directly to your TV for simple control and audio playback, turning your living room into a focused entertainment hub. This integrated amplifier is ideal for music enthusiasts who value clean dynamics, balanced tonality and wide connectivity.
Its layout is built for low noise operation, ensuring both streaming devices and physical sources benefit from consistent audio quality. With the supplied remote, you can switch inputs and adjust volume from your seat, making everyday use straightforward. From high resolution music sessions to immersive film nights, the B1xi delivers a confident performance that feels at home in any modern setup. Its blend of power, flexibility and ease of use makes it a strong choice for anyone seeking an upgrade that fits seamlessly into today’s listening habits.
In a Nutshell
Designed for today’s diverse listening needs, the B1xi features an array of input options. From the low-noise, high-gain MM phono stage, through multiple line-level inputs for other traditional sources, and onto the built-in DAC, HDMI ARC input and Bluetooth receiver for wireless streaming – each input is optimised for the best possible performance. There’s also an array of broader connectivity on offer, including the RCA variable pre-output for subwoofers or a dedicated power amplifier, a 5V USB-C power output for running an external streamer, a front-mounted mini-jack line input, and a headphone output for private listening sessions.
No WiFi by design
The only feature you might consider missing from the B1xi is Wi-Fi streaming – but that decision is deliberate. Where others might produce “all-in-one” streaming amplifiers, they often have to compromise on quality – or they become very expensive. Built-in streaming can also limit the amplifier’s lifespan, as when the playback technology is superseded, the hardware can often become unusable or less functional. At Musical Fidelity, everything is produced with a focus on good hardware, robust design, and a desirable sound quality that means your investment can last for decades. The B1xi can play nicely with any external streamer, and by keeping the source device separate you can guarantee the amplifier can play at the heart of your system for years to come.
Pure Class A/B Excellence with True High-End Audiophile Design
The B1xi benefits from a premium amplifier design, using transistor amps in Class A/B to deliver a highly engaging, tube-like sound. Delivering 60 watts into 8 ohms (100W, 4Ω / 140W, 2Ω), it doesn’t struggle to drive a wide variety of speakers. There’s a good degree of headroom on offer for proper peak power delivery and a wide dynamic range, meaning your listening experience is never strained. The pre-amplifier section of the B1xi features its own dedicated linear power supply, ensuring ultra-low noise and excellent channel separation. This design effectively treats the integrated amplifier as electrically separate pre- and power-amp stages. Volume control is handled via a motor-driven analogue potentiometer for the purest signal control.
Premium Throughout
The internal layout of the B1xi is optimised for perfect sound – despite the many features that are included. Once you take the lid off, you can see that the potentially interference-inducing digital boards are physically separated into their own PCBs with their own linear power supply. Other signs of quality are found in the amplifier’s industrial design. The robust metal controls on the extruded aluminium front panel merge stylishly with the metal chassis, giving a sense of control and reliability to every aspect of the design.
