Anthem STR Integrated Amplifier

Powering the Future of Audio.

The revolutionary STR Integrated Amplifier is based on an entirely new technological platform, for true benchmark performance in stereo amplification. More power, more control, more connection options, and the most advanced technology available in a single, easy-to-use component.

Designed, engineered, and Crafted in Canada, the STR Integrated Amplifier combines the benefits of an advanced preamp with the power of a massive amplifier and processor. It includes leading-edge DAC, onboard Anthem Room Correction (ARC®®), customizable bass manager for mono or stereo sub outs, MM and MC phono inputs—far more than the average integrated amp.

And it includes new generations of many of Anthem’s award-winning, audiophile-loving, review-praised digital signal processing innovations, delivering a noticeably higher level of audio performance realism.

This is the integrated amplifier with the power, features, connections and control to fuel your two-channel dreams, today and into tomorrow.

Two-Channel Nirvana

The STR Integrated Amplifier, with more power, control, connections and technology, will change your perception of two-channel amplification. Now, you can have it all, in one component, with the kind of superior response that Anthem is famous for. This is the integrated amplifier with the power, features, connections and control to fuel your two-channel dreams, today and into tomorrow. The critically acclaimed DSP innovations deliver a noticeably higher level of performance realism.

Subwoofer Options

STR Integrated Amplifier gives you more options for subwoofer configuration. Use one subwoofer or two for both channels, or two independent right-and-left channel specific subwoofers. The bass management in conjunction with ARC is uniquely engineered for seamless subwoofer blending, achieving an incredibly accurate and lifelike performance.

Massive Toroidal Power

The STR delivers incredible dynamics thanks to a massive, conservatively rated power supply engineered exclusively in-house at Anthem and designed with high rail voltages. The advanced-generation toroidal power transformer minimizes stray magnetic field radiation and ensures ultra-quiet performance. The resulting power is pure, clean, low-noise; capable of effortlessly and instantly reproducing the full dynamics of even the most complex audio recordings.

This massive power supply operates in harmony with the high-current, high-output amplifier section to produce an astounding 550W per channel continuously into 2 ohms. Peak production is effortless and instantaneous, cinching even the most challenging material. The use of multiple bipolar output devices dramatically reduces distortion while ensuring extreme linearity, extensive bandwidth, and stress-free reliability.

MM and MC Cartridges

Anthem has also taken into consideration the resurgent popularity of vinyl long-playing records and has included separate inputs for moving magnet and moving coil cartridges, with the phono section completely shielded to maintain signal purity. The transparency and refinement of the STR Integrated Amplifier reveals the hidden magic of classic media.

Innovative Electronics

Anthem’s non-invasive Advanced Load Monitoring (ALM) circuitry protects the output section by constantly monitoring temperature, current and voltage to ensure optimum long-term performance. The STR has more useful features than the average integrated amp, with no filler. Everything is geared toward giving you the power and control you need to achieve two-channel nirvana. The large Thin Film Transistor (TFT) display on the front panel can be seen from across the room, and gives you surprisingly easy control over your whole system. It’s a part of the luxurious new industrial design of the STR Integrated Amplifier, a striking look that’s available in two beautiful finishes, Black or Silver.
