Musical Fidelity B1 xi Integrated Amplifier
The Musical Fidelity B1xi integrated amplifier delivers 100W per channel into 4 ohms through a refined Class A/B circuit, offering a rich and dynamic tube-like sound. It features a comprehensive input selection including MM phono, coaxial and optical digital inputs, ARC, Bluetooth, and three RCA line inputs. A variable RCA pre-out supports subwoofer connection or bi-amping, and a 5V USB-C output provides power for an external streamer. Encased in robust all-metal construction with solid metal controls and a solid aluminum front panel, the B1xi offers superior sonic and build quality. It deliberately omits Wi-Fi streaming to maintain affordability and focus on sound quality.
