The STR Preamplifier is the result of deliberate choices, not compromises. We’ve masterfully combined an advanced analog preamplifier with the power of a digital processor, meticulously handling every signal with a leading-edge DAC and our proprietary Anthem Room Correction (ARC).
Unlike conventional preamplifiers, the STR is a masterfully engineered hub where every function is a deliberate choice. It's built to reveal every last nuance of your music, ensuring a flawless signal path from any source—from its MM and MC phono inputs to its digital connections. With our digital signal processing innovations, the STR Preamplifier doesn't just process sound; it orchestrates it, providing you with the authority needed for two-channel nirvana.
The STR Preamplifier's high-resolution section is engineered for one purpose: to deliver an audio signal of absolute purity. It meticulously handles every source, from its high-resolution preamplifier section to its leading-edge digital processing. Lower-resolution sources are intelligently up-sampled to 32-bit/192kHz, while our Asynchronous USB Audio Input accommodates the most demanding files, including 32-bit/384kHz PCM and DSD. With a full complement of inputs—including coaxial, optical, and AES/EBU inputs up to 192kHz, as well as balanced and single-ended analog, MM, and MC phono inputs—the signal path is always flawless.
The STR Preamplifier is designed as a central hub for total command. We engineered features to give you complete authority over your system, from its Home Theater Bypass Mode (which works without having to turn the power on and includes RCA/XLR input for two subs) to the ability to create up to 30 virtual inputs for setup flexibility. You can match sources and minimize distortion with adjustable analog input levels, and a graphic front panel display makes navigation intuitive. Complete control is at your fingertips, whether through the supplied IR remote or via Ethernet and RS-232 for seamless integration into any control system.
We take a holistic view of the digital-to-analog conversion process. Instead of boasting about a single component, we engineered the entire DAC stage to be a flawless signal path. A dedicated, asynchronous 32-bit/192 kHz sample rate conversion optimizes the anti-imaging filter, ensuring unmatched audio purity regardless of the input format. This process also re-clocks the data, providing immunity from performance-marring source jitter. Throughout the DAC circuitry, thin-film high-precision resistors and ultra-low noise op-amps are used to achieve the lowest possible distortion, noise, and the most transparent sound. There are simply no bottlenecks.
The STR Preamplifier gives you more configuration options for bass management than a conventional preamp. You can use one or two subwoofers for both channels, or configure two independent, channel-specific subwoofers. When used with Anthem Room Correction (ARC®), this system is uniquely engineered for seamless subwoofer blending, achieving incredibly accurate and lifelike performance. Recognizing the resurgent popularity of vinyl, we've included separate, shielded inputs for both moving magnet and moving coil cartridges. The phono section’s meticulous design ensures a clean signal that reveals the hidden magic of classic media. For those with vintage collections, the continuously adjustable phono curve allows for proper playback of any record that predates the RIAA equalization standard.
Our commitment to audio purity extends to every source. Acknowledging the resurgence of vinyl, the STR Preamplifier features a dedicated, meticulously shielded phono section with separate inputs for both moving magnet (MM) and moving coil (MC) cartridges. This unwavering attention to detail maintains flawless signal integrity, ensuring the transparency and refinement of the STR reveal the hidden magic of your classic media.
Engineered and manufactured with a defiant, independent spirit, the STR Preamplifier is proudly Made in Canada. Our commitment to local design and production allows our engineers to maintain absolute control over every detail, ensuring the final product delivers an experience defined by uncompromising quality and performance.
