    Push the Power of Audio Control.

    Audiophile Pre Amplifier with DSD DAC, MM/MC Phono, HT Bypass and Full Room Correction.

    From the Martin Logan Stable, comes the revolutionary Anthem STR Preamplifier - 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, onboard Anthem Room Correction (ARC™), customizable bass manager for mono or stereo sub outs, MM and MC phono inputs—far more than the average preamplifier.

    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.
    The new STR Preamplifier drives all of your entertainment options today, and tomorrow.


    • High-resolution analogue and digital preamplifier
    • Anthem Room CorrectionTM(ARC) to optimize in-room response
    • Bass management for two subwoofers, in mono or stereo
    • Up-sampling of lower-resolution sources to 32-bit/192kHz
    • Asynchronous USB audio input supports 32-bit/384kHz PCM, and DSD 2.8 / 5.6 MHz sources
    • Coaxial,optical, and AES/EBU inputs up to 192kHz
    • MM and MC phono, balanced XLR, and single-ended
    analogue inputs
    • Six pre-RIAA curves plus adjustable settings for playing older records accurately
    • Analogue Direct Mode
    • Adjustable analogue input levels to match sources,minimize
    noise and prevent distortion
    • Graphic front panel display for easy setup navigation
    • Balanced output for all channels including the two subs

    • Create up to 30 virtual inputs for setup flexibility

    USB DSD 5.6MHz DAC

    Get premium sound quality from your Music Streamer or Windows or Mac laptop.
    The Anthem STR Pre Amplifier uses a high-quality, asynchronous USB audio input to translate digitally stored music into superb analogue sound.

    The STR Preamplifier includes the newest and most powerful generation of Anthem Room Correction (ARC), with 50% more processing power than any other version of ARC. This proprietary calibration tool, with its easy-to-use interface, automatically shapes the acoustic signature of your speakers for the best possible sound quality in your unique listening space.

    Other innovations include a high- resolution preamplifier and digital section, which supports asynchronous USB up to 32-bit/384 kHz PCM and DSD 2.8/5.6 MHz sources, and uses signal processing that employs 64-bit accumulation and feedback to preserve the finest detail in the music and to avoid degradation. The digital to analog conversion section was designed to faithfully duplicate all the sounds in the original source.

    To help achieve that effect for all input resolutions, a dedicated asynchronous 32-bit / 192 kHz sample rate conversion
    is used. This way, the DAC stage’s anti- imaging filter is optimized for this sampling rate alone, resulting in an audio frequency range that’s unmatched in purity, regardless of input format. In the process, the data gets reclocked, providing immunity from performance-marring source jitter.

    Through the rest of the DAC circuitry, thin film high precision resistors and super low noise op-amps are used for lowest distortion, lowest noise, and most transparent sound. Other DAC units may boast about the performance of the DAC chip all by itself, but we view DAC stage design as a whole — there are no crippling bottlenecks anywhere in the DAC stage of the STR Preamplifier.

    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.

    More Subwoofer Options

    The STR Preamplifier 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 incredibly accurate and lifelike performance.

    Moving Coil and Moving Magnet Phono

    Anthem has also taken into consideration the resurgent popularity of vinyl records, and has included separate inputs for moving magnet and moving coil cartridges, with the phono section completely shielded to maintain a clean signal.

    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 equalization standard.

    Home Theater Bypass

    The concept of combining a stereo preamplifier with a home theater system is taken to a whole new level.

    The STR Preamplifier 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.

    Premium Components

    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 analogue to digital circuitry to cancel artifacts and keep noise to a minimum.

    Audio optimized for any space

    The STR Preamplifier features exclusive Anthem Room Correction (ARCTM) Technology.

    ARC uses a calibrated microphone and advanced DSP algorithms to quickly and easily optimize
    speaker performance in any space. In just a few easy steps the microphone measures sound output, compares it to scientifically optimal  response curves , for perfect sound. You’ll actually hear the difference ARC makes.

    The STR Preamplifier also supports ARC Mobile, making Anthem Room Correction (ARCTM) even easier to use. 


    Solid build quality works in concert with clean, clear, audiophile-quality sound throughout the frequency spectrum.
