Antham STR Amplifier

The STR Power Amplifier is the beating heart of a world-class sound system, a statement in unwavering performance. As our flagship power amplifier, it is engineered to deliver immense power and audiophile-quality output in a single, elegantly designed component.

Designed, engineered, and Crafted in Canada, the STR Power Amplifier delivers 400 Watts/channel into 8 ohms, 600 Watts/channel into 4 ohms, and a staggering 800 Watts/channel into 2 ohms—all with both channels driven. This is true no-holds-barred performance, providing immense headroom and effortless dynamics.
