Classic Amplifier Technology

MUSICAL FIDELITY has been developing and building amplifiers for over four decades, with the consistent goal of effortlessly driving any loudspeaker design. The key is high current delivery – the ability to supply sufficient current to the transistors for even the most demanding musical passages.

While many amplifiers in this class rely on large capacitor banks, MUSICAL FIDELITY has always favored generously dimensioned power supplies, centered around a substantial toroidal transformer. Although more expensive, this approach is considered the best path to superior sound.

In the pre-amplifier stage, MUSICAL FIDELITY also makes no compromises, equipping the B1xi with fully discrete Class-A pre-amplification.

Extensive Features

The B1xi is the answer to all your audio needs. From turntables to TVs, Bluetooth to CDs, everything connects to the central hub that is the B1xi.

Rear Panel Description: The rear panel features a comprehensive array of connections, including speaker outputs (banana/spade/bare wire), pre-outs, a subwoofer output, a 6.3mm headphone jack, and various input terminals such as Phono (RCA), analog LINE (RCA), digital COAX, digital Toslink, and HDMI ARC. A USB-C port is also present for power output, suitable for accessories like streamers. An external Bluetooth antenna ensures a stable wireless connection.

Timeless Design and Highest Casing Quality

The casing adheres strictly to the tradition of MUSICAL FIDELITY, featuring all-metal construction. The robust 10mm thick front panel is milled from solid aluminum through an intricate process. Elegant device feet not only contribute to the refined aesthetic but also ensure constant convection cooling for the audio circuitry.
