Brand: Ess

The ESS AMT-1 (Active Matching Transformer-1) is a high-performance headphone amplifier produced by ESS Technology, a California-based fabless semiconductor company. The AMT-1 is designed to provide high-quality amplification for demanding headphone applications, particularly those that require low-distortion, high-dynamic range, and high output power.The key feature of the AMT-1 is its Active Matching Technology (AMT), which compensates for the electrical impedance and frequency response characteristics of different headphone types, ensuring consistent and accurate sound reproduction. This technology is achieved through a feedback network that uses a dual-amplifier architecture and a custom cap filter, optimized for ultra-low THD+N and THD alone.The AMT-1 also features a top-quality opamp, high-speed BJT and MOSFET switches, and a low-noise voltage regulator, all integrated into a compact and low-power package. This design approach delivers 1-2x improvement in Signal-to-Noise Ratio (SNR) over other amplifier solutions in the market.In summary, the ESS AMT-1 is a high-performance headphone amplifier that offers Active Matching Technology, low-distortion, high-dynamic range, and high output power, making it an excellent choice for demanding headphone applications.
