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.

Two-Channel Nirvana.
More power, more control, more connections, more technology. The STR Integrated Amplifier will change your perception of two-channel amplification. Now, you can have it all, in one component, with the kind of superior response and realism that Anthem is famous for.
More 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 engineered for seamless subwoofer blending, achieving an incredibly accurate and lifelike performance.
More Attention to Detail
We believe that 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 analog to digital circuitry to cancel artifacts and keep noise to a minimum.
More Power, From Oversized Toroidal Transformers
Clarity is maintained using carefully selected components, many of them engineered exclusively in-house at Anthem, like the huge, precision-wound toroidal transformers and their matching oversized filter capacitors. 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.
Moving Magnet and Moving Coil 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.
More Innovative Electronics
No less important is Anthem’s non-invasive Advanced Load Monitoring (ALM) circuitry, which protects the output section of the STR Integrated Amplifier by constantly monitoring temperature, current and voltage to ensure optimum long-term performance.
And there’s more. The STR Integrated Amplifier 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.
Aside from its cutting-edge technology and Anthem-exclusive innovations, one look tells you that the STR is a different amplifier animal altogether. 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.
The Crafted in Canada Difference
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.
A True Scientific Solution to the Problems of Your Room
What is ARC® ?
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.
How does ARC® work?
ARC digitally compares a room’s acoustic signature to that of the lab standard. It measures the response of each speaker relative to the listening area. Then it uses advanced algorithms to eliminate the negative effects of the obstacles in the room, adjusting response and correcting phase effects. When ARC removes the obstacles, what’s left is the lab standard performance.
ARC is easy to use, and just a few simple steps can optimize your speakers for your unique listening space. ARC is sophisticated, one of the most accurate and detailed digital room correction technologies available today. ARC will work tomorrow, too; with constant advances and updates available for download on the Anthem website.

Anthem STR Integrated Amplifier
The Anthem STR pairs muscular Class‑AB power with refined, neutral voicing and studio‑grade DSP. Reviewers from HiFi Choice and SoundStage Solo note its 200W‑per‑channel headroom, effortless dynamics and tight, textured bass. The built‑in MM/MC phono and a natural‑sounding DAC deliver revealing mids and smooth treble, while precise imaging and room‑correction (ARC/ARC‑2) let the STR adapt to real rooms. Construction is substantial — toroidal transformer, oversized caps and a clear TFT display — and connectivity is comprehensive (XLR, USB‑B 32/384, AES, coax/optical, dual sub outs). Ideal for vinyl fans, digital‑first systems and listeners who want separates‑level performance with modern features. For its class the STR represents a compelling, well‑engineered value.
Pros
- Powerful, controlled dynamics and headroom: Class‑AB 200Wpc delivers effortless transients and refuses to distort even at high levels.
- Excellent analogue and digital front end: natural, revealing DAC plus quiet, well‑engineered MM/MC phono stage for vinyl and digital parity.
- Anthem Room Correction (ARC/ARC‑2) is effective and flexible for taming room modes and integrating subwoofers, improving bass control and coherence.
- Robust build and comprehensive connectivity: beefy toroidal transformer, oversized caps, clear display and wide I/O (XLR, AES, coax/optical, USB‑B, dual sub outs, virtual inputs).
&
Cons
- No front‑panel headphone output — a notable omission for listeners who expect a dedicated headphone path.
- Room correction can, in some setups, slightly flatten the sonic image or homogenize micro‑detail compared with direct analogue feeding.
- Home‑theatre bypass does not pass subwoofer signals, which can limit convenience for systems that use subs across stereo and AV modes.
Sound Quality

Dynamics
92/100
Class-AB 200W-per-channel topology with large transformer underpins excellent headroom; reviewers repeatedly note 'impressive power reserves', 'effortless transients' and that the amp 'refused to distort' even at very high levels (SoundStage, HiFi Choice, StereoNET). ARC engagement further improves composure and punch, justifying an excellent dynamics score in the Class-AB 100–200W band.
Soundstage Imaging
91/100
Most reviewers report strong separation, good depth and stable imaging — often describing a 'highly compelling soundscape' and 'remarkable separation' (StereoNET, Future Audiophile, SoundStage). A small number note a slightly flattened presentation with certain ARC settings, but overall staging and imaging are consistently praised.
