The revolutionary STR integrated amplifier is based on an entirely new technological platform for true benchmark performance in stereo amplification that compounds 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, STR combines the benefits of an advanced preamp with the power of a massive amplifier and processor. It includes a leading-edge DAC, onboard Anthem Room Correction (ARC™), customizable bass manager for mono or stereo sub outs, and MM and MC phono inputs to provide far more than the average integrated amp.

It integrates new generations of many of Anthem’s award-winning, audiophile-loving, review-praised digital signal processing innovations to deliver a noticeably higher level of audio performance realism.
