STR Integrated Amplifier

About the STR Integrated Amplifier

The Anthem STR Integrated Amplifier is a high-performance two-channel amplifier designed to deliver superior power, control, and audio fidelity. It features a Class AB, dual mono design with a massive toroidal power supply and oversized filter capacitors, producing 200 watts per channel into 8 ohms, 400 watts into 4 ohms, and an impressive 550 watts into 2 ohms continuously (20 Hz - 20 kHz, <1% THD). The amplifier uses multiple bipolar output devices to reduce distortion, ensure linearity, and provide extensive bandwidth with stress-free reliability. It supports a wide range of digital inputs including S/PDIF coaxial and optical, balanced AES/EBU, and asynchronous USB audio input capable of 32-bit/384kHz PCM and DSD 2.8/5.6 MHz sources. The STR also includes MM and MC phono inputs and advanced bass management with options for one or two subwoofers, including independent left and right channel subwoofer configurations, integrated with Anthem's ARC room correction technology for seamless subwoofer blending. The design emphasizes short signal paths and differential analog-to-digital circuitry to minimize noise and artifacts, maintaining flawless signal integrity. The amplifier is built with advanced protective technologies such as Advanced Load Monitoring and DSP-based fault condition monitoring to ensure long-term reliability and stable operation under difficult low-impedance speaker loads. Overall, the Anthem STR Integrated Amplifier combines extreme power, delicate transparency, and detailed control in a single component, making it a top-tier choice for two-channel audio enthusiasts.
