Product Description

Anthem STR Integrated Amplifier is based on an entirely new technological platform, for true benchmark performance in stereo amplification, combining the benefits of an advanced preamp with the power of a massive amplifier and processor. It includes leading-edge DAC, onboard ARC, customisable bass manager for mono or stereo sub outs, MM/MC phono inputs more than the average integrated amp.

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.


Digital/Analogue Conversion

STR Integrated Amplifier includes a high-resolution pre-amplifier and a digital section, with support for asynchronous USB up to 32-bit/384 kHz PCM and DSD 2.8/5.6 MHz sources. This high-quality USB audio input transforms digitally stored audio from your Windows or Mac computer into warm, natural analogue sound.

Hand-Built Quality Components

Anthem STR Integrated Amplifiers are designed, engineered, and Crafted in Canada. From the idea stage to the final manufacturing specs, Anthem has complete control over the whole intricate process and take pride in this personal attention to detail. They use only the highest quality components, many designed and engineered in-house, in each new STR Anthem hand-build for your enjoyment.

Audiophile Binding Posts

Big power demands big connections and custom-designed oversized five-way binding posts give you the flexibility you need for even large-gauge bare-wire connections. Insulated, non-conductive, colour-coded jackets make easy, fast, and solid connections with no interference or ghosting.

Rock Solid Performance

Anthem amplifiers go where other amplifiers fear to tread, with a well-earned reputation for being incredibly stable under difficult, low-impedance speaker loads. Short path design, superior DAC, and redundant systems (with Advanced Load Monitoring and other exclusive protective technologies) ensure that peaks are surmounted effortlessly, and guarantee a long life of high performance.

Anthem Room Correction

ARC is a proprietary digital signal processing system that allows you to quickly and accurately optimize the performance of your audio equipment to better suit the unique parameters of your room. By listening to your room’s acoustic signature, ARC can tune your equipment to correct for the performance-robbing effects (reflections, resonances, standing waves, etc.) of the various surfaces and other obstacles in your room. You’ll actually hear the difference ARC makes.

Attention to Detail

Two-channel listening demands attention to detail. A component must balance extreme power and delicate transparency, with flawless signal integrity being the benchmark of stereo performance. To that ultimate end, the Anthem STR Integrated Amplifier is designed with the shortest possible signal paths, and differential analogue to digital circuitry to cancel artefacts and keep noise to a minimum. The STR Integrated Amplifier is designed, engineered and manufactured in Canada and is part of premium STR Series by Anthem, the leader in audio power and control.
