A Modern Revival of a British Audiophile Classic

The Musical Fidelity B1X is a reimagined version of the iconic 1980s B1 integrated amplifier — now upgraded with enhanced internals, improved connectivity, and a refined sound signature, all while preserving the minimalist aesthetic that made the original a cult favorite. Designed and built in the UK, the B1X delivers rich, musical sound with high headroom, effortless dynamics, and broad compatibility. Whether you're pairing it with bookshelf speakers, floorstanders, or using it as the heart of a compact high-end setup, the B1X offers pure analog performance in a timeless package.

True Analog Sound

Built with discrete componentry and carefully selected circuitry, the B1X delivers a warm, dynamic, and natural sound that captures the essence of true high-fidelity music playback.

Upgraded Power & Performance

The B1X improves upon the original B1 with a robust 40 watts per channel (8 ohms) and increased current delivery, allowing it to drive a wide range of speakers with authority and finesse.

Phono Stage Included

Built-in MM (Moving Magnet) phono stage lets vinyl lovers connect turntables directly, offering smooth analog performance with impressive detail and quiet backgrounds.

Modernized Inputs

Featuring four line-level RCA inputs plus the phono input, the B1X accommodates CD players, streamers, DACs, and more. A high-quality headphone output adds flexibility for private listening.

Elegant British Design

The compact chassis features solid metal construction and classic rotary knobs, maintaining the original B1's iconic design while ensuring durability and ease of use.

Hand-Assembled in the UK

Built with pride in the United Kingdom using modern manufacturing techniques, the B1X reflects Musical Fidelity’s long-standing reputation for craftsmanship and sonic integrity.
