Products that are Awaiting Stock are items that we would normally carry on stock at our Oxfordshire warehouse, but are currently unavailable. Chances are there is already more on the way, but if you would like a more accurate availability status please feel free to Contact Us.
Urgent order items are products that we do not normally carry on stock, but they are typically held on stock by our European suppliers. Depending on availability, we will seek to order these products quickly, when we have an enquiry. They can therefore be subject to quicker availability times than "Special Order" products.
Special Order items are those that are most often built to order. For these items, we tend to experience longer lead times as we negotiate them into the production line with our suppliers.
Exclusive products are sold only through one, or sometimes a very small number of dealers. As part of their commitment to the product’s exclusivity, they carry most of the available stock.

The B1xi distils Musical Fidelity’s renowned amplifier expertise into a versatile, high-performance integrated amplifier suited to the modern listener’s requirements. Featuring a purpose-designed Class A/B circuit with 60W (8Ω) power output, there’s little this amplifier cannot work with.
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.
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 Built-in streaming can also limit the amplifier’s lifespan, as when the playback technology is superseded, the hardware can often become unusable or less functional.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.
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.
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.
The B1xi is a true hi-fi amplifier, designed by music lovers. By focusing on good design principles and high-end sound performance, and equipping the design with good connectivity options, this is the ideal system hub for anyone looking for great sound at an affordable price.
