About the Musical Fidelity B1xi Integrated Amplifier
Product Description
B1xi
The B1xi integrated amplifier channels Musical Fidelity’s renowned amplifier expertise into a versatile, high-performance package. Driven by the design principles of Musical Fidelity’s flagship models, the B1xi delivers 100W per channel into 4 ohms through a refined Class A/B circuit, offering a rich and dynamic tube-like sound.
Designed for today’s diverse listening needs, it features a comprehensive input selection: MM phono stage, coaxial and optical digital inputs, ARC, Bluetooth, and three RCA line inputs—all engineered for seamless source integration. A variable RCA pre-out supports subwoofer connection or bi-amping, while a 5V USB-C output provides convenient and clean high-quality power for an external streamer.
Encased in robust all-metal construction with solid metal controls and a solid aluminium front panel, the B1xi offers the sonic and build quality Musical Fidelity is known for, delivering a pure, uncompromised audio experience for discerning music lovers.
Pure Class A/B Excellence with True High-End Audiophile Design
Transistor amps in Class A/B are best after tubes and Class A amps. Musical Fidelity is tube like sound and power.
The B1xi delivers 60 watts per channel into 8 ohms, 100 watts into 4 ohms and 140W peaks into 2 ohms. It won’t struggle to drive a wide range of speakers, even power-hungry models.
Discrete power and toroidal transformer
The fully discrete Class A/B power amp, complemented by its dedicated power supply and generously proportioned toroidal transformer, guarantees reserves for proper peak delivery and a wide dynamic range.
Power hungry and difficult speakers are driven with ease. Low impedance dips are managed gracefully and the judiciously rated output devices won ‘t faulter under any load.
Low noise preamp and phono stage
The preamp section features its own dedicated linear power supply—a rarity in integrated designs. This separation ensures ultra-low noise and excellent channel separation, rivalling high-end pre/power separates. Volume control is handled via a motor-driven analogue potentiometer, preserving signal purity—unlike many modern digital volume controls that compromise fidelity due to a loss in signal resolution.
Vinyl lovers will appreciate the B1xi’s exceptionally low-noise, high-gain phono stage. Carefully tuned for musicality and detail, it brings out the best in your MM cartridges without adding coloration or distortion.
Separate digital boards
Digital and analogue hardware needs to be carefully separated from each other.
Even the smallest amount of RF interference is known to cause trouble for analogue amplifier stages.
Therefore, the digital and ARC boards are physically separated on their own PCBs and have their own linear power supply.
Drawing from Musical Fidelity’s decade long experience in designing DACs (recently with their ground-breaking Nu-Vista DAC and M8x DAC), the B1xi uses a carefully trimmed DAC design using the superb ESS9018 chip.
The digital coaxial and optical inputs accept high-resolution sample rates up to 24bit and 192kHz and the ARC input allows your home theatre to be brought to life and properly invigorated by the powerful B1xi analogue amp stages.
Uncompromisingly heavy mechanical design
The inclusion of high-end elements such as the robust metal controls, extruded aluminium front panel, and a chassis crafted entirely from metal, the B1xi occupies an enviable position for discerning audiophiles seeking an unadulterated high-end amplifier.
No WiFi on Purpose
The B1xi remains committed to sound quality instead of WiFi, a display and an App.
There is NO WiFi streaming on purpose. We’ve seen a surge in offerings from HiFi companies with all-in-one solutions and unfortunately, such developments are HUGLY EXPENSIVE and on top very maintenance heavy.
Consequently, manufactures started to save the money somewhere: Cheap plastic cabinets, low-cost digital amplifiers, low-cost power supplies.
Musical Fidelity stands for sound quality and robust design that lasts for decades. They INVEST their money and resources in top-tier hardware and the pursuit of optimal music reproduction. This means: Robust mechanics - Discrete circuits - Huge. transformers - Class A/B amps.
Fast moving streaming technology is best kept separate and therefore will not negatively impact the lifecycle of the B1xi.
For that reason, the B1xi features a high-quality isolated USB C 5V power output for your favourite modern streamer – effectively also doubling as a power supply upgrade for it.
