Key Features
The revolutionary STR Preamplifier is a new type of audio component that gives you more control and more refinements, including more connection options and more advanced technology, in a single, easy-to-use component.
Designed, engineered, and Crafted in Canada, the STR Preamplifier combines the benefits of an advanced preamp with the power of a processor, as well as functions like leading-edge DAC, on board Anthem Room Correction (ARC), customizable bass manager for mono or stereo sub outs, MM and MC phono inputs—far more than the average preamplifier.

The revolutionary STR Preamplifier is a new type of audio component that gives you more control and more refinements, including more connection options and more advanced technology, in a single, easy-to-use component.
Designed, engineered, and Crafted in Canada, the STR Preamplifier combines the benefits of an advanced preamp with the power of a processor, as well as functions like leading-edge DAC, on board Anthem Room Correction (ARC), customizable bass manager for mono or stereo sub outs, MM and MC phono inputs—far more than the average preamplifier. It also 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.
Aside from its cutting-edge technology, one look tells you that the STR Preamplifier is a different animal altogether. The display on the front panel gives you surprisingly easy control through an easy to navigate setup menu, and the luxurious and elegant new contemporary design is available in two beautiful finishes, Black or Silver.
Anthem Room Correction (ARC) is a proprietary digital signal processing system that allows you to quickly and accurately optimise 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.
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 preamplifier reveals the hidden magic of classic media. In addition, the phono curve is continuously adjustable for proper playback of any record that predates the RIAA equalisation standard.
Clarity is maintained using carefully selected components, many of them engineered exclusively in-house at Anthem. We believe that two-channel listening demands attention to detail, with flawless signal integrity being the benchmark of stereo performance. To that ultimate end, the Anthem STR Preamplifier is designed with the shortest possible signal paths, and differential analog to digital circuitry to cancel artifacts and keep noise to a minimum.
STR Preamplifier includes a high-resolution preamplifier 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.
The concept of combining a stereo preamplifier with a home theatre system is taken to a whole new level. The STR Premplifier supports two subwoofer channels in addition to the two fronts. XLR as well as RCA connection is provided for all channels, and HT Bypass mode engages while the preamp is on standby. This way, you don't have to turn it on when watching movies. To allow the purest signal path, relays are employed to hard-wire the input jacks to the outputs - the STR Preamplifier essentially becomes a straight wire.
