Musical Fidelity B1xi: High-Performance Integrated Hi-Fi Amplifier

The B1xi distills Musical Fidelity’s renowned heritage in reference amplifiers into a versatile, robust design tailored to today’s listeners. Featuring a fully discrete Class A/B amplification stage, the B1xi delivers 60 W per channel into 8 ohms, 100 W into 4 ohms, and peaks of 140 W into 2 ohms, ensuring a dynamic, refined sound with the tonal richness often associated with valve designs.

True to Musical Fidelity’s philosophy, the B1xi emphasizes solid build quality, precision engineering, and uncompromising audiophile sound, without unnecessary extras such as Wi-Fi or built-in displays that could compromise signal purity.

Effortless Power & Musicality

The Class A/B design, supported by a high-capacity toroidal transformer and dedicated power supplies, guarantees sustained output and wide dynamic range. Hand-matched output devices ensure stability under any load, even with demanding loudspeakers.

Low-Noise Preamp & MM Phono Stage

The preamplifier features its own independent linear power supply for minimal interference and exceptional channel separation. A motorized analog potentiometer handles volume control, preserving signal integrity without digital loss.

Vinyl enthusiasts will appreciate the integrated MM phono stage, offering gain and musicality on par with higher-tier models.

Comprehensive Connectivity

The B1xi is designed for seamless integration into any modern Hi-Fi setup:

Analog inputs: 1 × MM phono, 3 × RCA line

Digital inputs: 1 × coaxial, 1 × optical, 1 × HDMI ARC

Wireless: Bluetooth 5.1 high-quality streaming

Outputs: variable RCA pre-out for subwoofer/bi-amping, 5V USB-C for powering an external streamer

Optimized Digital Design

Digital boards and the ARC section are isolated on dedicated PCBs with their own linear power supplies, preventing RF contamination of the analog stages. The built-in ESS9018 DAC supports up to 24-bit/192 kHz decoding, delivering transparency and precision across the full frequency range.

Audiophile Mechanical Construction

Musical Fidelity stays true to its standards with:

All-metal chassis

Extruded aluminum front panel

Premium-grade metal knobs and controls

Internal shielding against RF interference
