About the A1
The Musical Fidelity A1 Integrated Amplifier is a faithful reimagining of the legendary 1985 original, renowned for its pure Class A operation and ability to drive demanding speakers despite modest power ratings. The 2023 version preserves the original's discrete symmetrical topology and sonic character, while incorporating modern improvements such as a dual mono split rail transformer, updated low-noise components, and a motorized ALPS volume potentiometer with remote control. The amplifier features a high-quality MM/MC phono stage, five line-level inputs, tape out, and pre out, all in a robust chassis with enhanced heat dissipation and power supply capacity. The A1 remains a benchmark for musicality and build quality in integrated amplifiers.
