The revolutionary STR preamp 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, STR 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, customizable bass manager for mono or stereo sub outs, MM and MC phono inputs.

It's far more than the average preamplifier. It integrates 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.
