Anthem STR Integrated Amplifier

Overview

The Anthem STR Integrated Amplifier combines a full preamplifier, high-current power amplifier, and reference-grade DAC in one Canadian-made chassis, delivering 200 watts per channel into 8 ohms, 400 watts into 4 ohms, and 550 watts into 2 ohms. A front-panel Thin-Film Transistor display puts full system status and control at your fingertips, giving you separates-level performance without a rack full of components.

Built-in Anthem Room Correction (ARC Genesis) measures your room with the included calibrated microphone and tripod, then corrects the acoustic issues that flatten bass and blur imaging without touching the natural voice of your speakers. Independent bass management for up to two subwoofers gives you precise control over low-frequency blending, whether you're running one sub or two.

Two dedicated phono stages, one for moving magnet and one for moving coil cartridges, sit alongside a full set of digital inputs that upsample lower-resolution material to 24-bit/192kHz, while the asynchronous USB input decodes native DSD and 32-bit/384kHz PCM straight from a network streamer or computer.

Simcoe Audio Video Insight

Most listeners have to choose between the separation of true separates and the simplicity of an all-in-one amplifier. The STR Integrated closes that gap by keeping every internal section, preamp, DAC, and power amp, built and isolated to the same standard you'd expect from standalone Anthem components, just sharing one chassis and one power supply. For a great room or open-concept living space where you don't want a stack of boxes on display, this is the way to get reference-level two-channel sound without sacrificing the room's design.

Why the Anthem STR Integrated Amplifier Stands Out

High-Current Amplifier Section

Eight heavy-duty bipolar output devices per channel deliver instantaneous peak power and stay stable into demanding 2-ohm loads.

Anthem Room Correction (ARC Genesis)

Maps your room's acoustic reflections with the included calibrated microphone and corrects bass buildup and frequency response issues digitally.

Dual Independent Subwoofer Outputs

Configurable crossover and phase settings for up to two subwoofers let you dial in tight, accurate low end for stereo or mono setups.

Reference Digital-to-Analog Conversion

Automatically upsamples lower-resolution digital sources to 24-bit/192kHz, and decodes native DSD and 32-bit/384kHz PCM over asynchronous USB.

Dual Phono Stages

Separate, dedicated inputs for moving magnet and moving coil cartridges give vinyl playback its own optimized signal path.

Advanced Load Monitoring (ALM)

Continuously tracks voltage, current, and temperature to protect the amplifier without placing fuses in the signal path.

Flexible System Integration

IP control over Ethernet, RS-232 serial, and 12-volt triggers connect the STR Integrated to Control4, Crestron, or other home automation platforms.

Buyer's Guide

Who It's For

  • Two-channel enthusiasts who want the separation and detail of standalone components without the extra chassis and cabling.
  • Vinyl collectors who move between moving coil cartridges and high-resolution DSD digital streams.
  • Homeowners furnishing a great room or open living space where system aesthetics matter as much as sound quality.

How It Compares

The STR Integrated packs a preamplifier, DAC, and power amplifier into one chassis, while the Anthem STR Preamplifier and STR Power Amplifier split those same functions into two dedicated components with independent power supplies for each channel. If your room and budget allow for two chassis, the separates pairing delivers even more channel separation and current headroom; if you want that same engineering standard in a single footprint, the STR Integrated is the way to get there.
