The STR Integrated Amplifier represents a new platform of power and control. We engineered this high-performance component to deliver an unprecedented level of authority, combining an advanced pre-amplifier with a massive power amplifier and a state-of-the-art processor.It is a complete solution that goes far beyond conventional integrated amps. The STR seamlessly integrates a leading-edge DAC, our onboard Anthem Room Correction (ARC), a customizable bass manager for mono or stereo subwoofer outputs, and both MM and MC phono inputs. Our digital signal processing innovations ensure a noticeably higher level of performance and realism. The STR Integrated Amplifier is built to drive all your entertainment today, and engineered to remain a benchmark for years to come.

The Science of a Pristine Signal

From the moment a signal enters the STR, it is treated with scientific precision. Its high-resolution preamplifier is designed for ultra-low noise and distortion.
Lower-resolution sources are intelligently up-sampled to 24-bit/192 kHz, while the asynchronous USB audio input supports up to 32-bit/384 kHz PCM and DSD 2.8/5.6 MHz sources. This meticulous process ensures a bit-perfect digital-to-analog conversion, preserving every detail and nuance of your music.

Unparalleled Control and Connectivity

The STR is engineered to be the nerve center of your audio system, offering a comprehensive suite of inputs and controls.

STR includes digital S/PDIF coaxial and optical inputs, a balanced AES/EBU input, and a variety of analog options including balanced XLR, single-ended, and both MM and MC phono inputs for turntable enthusiasts. For the purist, the Analog Direct mode bypasses all digital processing for a pristine, uncolored signal.

It also features advanced bass management for two subwoofers, allowing for precise, dual-subwoofer configurations in either mono or stereo.

Unlocking Vinyl’s Hidden Magic

Our commitment to audio purity extends to every source. Acknowledging the resurgence of vinyl, the STR Integrated Amplifier features a dedicated, meticulously shielded phono section with separate inputs for both moving magnet (MM) and moving coil (MC) cartridges. This unwavering attention to detail maintains flawless signal integrity, ensuring the transparency and refinement of the STR reveal the hidden magic of your classic media.
