Anthem STR Power Amplifier power amplifier

Anthem STR Power Amplifier power amplifier

The dual-channel revolution

The STR power amplifier is the heart of a world-class 2-channel audio system, delivering massive power generation and quality in an intelligently designed component.

Designed and manufactured in Canada, the STR Power Amplifier delivers 400 watts per channel into 8 ohms with both channels driven, a massive 600 watts per channel into 4 ohms (both channels driven) and 800 watts into 2 ohms, delivering truly unrivaled performance.

The STR Power Amplifier features two huge transformers and multiple high-current output devices, ensuring that even the finest details and dynamic peaks are handled with equal care. Its exterior is beautifully designed, featuring a 7-inch graphic control display, and secure, highly conductive audiophile-grade connectors, creating a perfect match with the STR Preamplifier.
