About the A1.5
The A1.5 is a Swiss-engineered, modular power amplifier that embodies the same sophisticated design philosophy as CH Precision’s flagship M1.1, but in a more compact and affordable package. It features a fully discrete, fully balanced, and fully complementary signal path, built with carefully selected components to exacting standards. The A1.5 is unique in offering user-configurable global feedback ratio and gain adjustments, allowing precise matching to virtually any loudspeaker. It supports five operating modes: stereo, monaural, bridge, and both active and passive bi-amplification. The amplifier is future-proof, with Ethernet control, USB firmware updates, and a cost-effective upgrade path. The chassis retains the same footprint and construction quality as the M1.1, and the power supply uses an identical transformer and reservoir capacitors, ensuring robust dynamics and low noise.
