Musical Fidelity B1XI

B1XI - Overview

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.

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.

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.
