The STR Power Amplifier is the beating heart of a world-class 2-channel sound system. It delivers massive power generation, with audiophile-quality output in a smartly designed component.

Anthem® STR Series SIlver 2 Channel Power Amplifier

Cascoded complementary feedback input stage

Sixteen bipolar output devices per channel

Inside, the STR Power Amplifier uses two colossal transformers and multiple high-current output devices so the most subtle details and dynamic peaks are handled equally well. Outside, its beautifully designed cosmetics, including a 7-inch graphic control display and secure, highly conductive audiophile connectors provide a perfect match to the STR Preamplifier.

Designed, engineered, and Crafted in Canada, the STR Power Amplifier delivers channel into 8 ohms with both channels driven, a massive channel into 4 ohms (both channels driven) and  in 2 ohms, for true no-holds-barred performance.

Cascoded Complementary Feedback Input Stage

The STR Power Amplifier benefits from our proprietary input topology—a unique departure from the classic differential input stage. Eight low-noise bipolar input devices are configured in a complementary active-load cascoded feedback arrangement for reduced distortion, exceptionally linear response and superior bandwidth. Transistors in critical stages are hand-selected and matched for lowest possible distortion.

Sixteen Bipolar Output Devices Per Channel

Anthem engineers incorporated sixteen bipolar output devices per channel, resulting in peak production that is effortless and instantaneous, cinching even the most challenging material. The use of multiple bipolar output devices in class AB configuration also dramatically reduces distortion while ensuring extreme linearity, extensive bandwidth, and stress-free reliability.

Experience the immense dynamics of up to clean watts delivered into demanding 2-ohm loads, or  into 8 ohms into 4 ohms continuously and with both channels driven.

Conservatively rated, in a low-profile design shaped to minimize hum, the low-impedance toroidal power transformers — one for each channel — make no sacrifices when it comes to delivering a continuous supply of pure, clean, low noise power. As well, both the power supply impedance and internal cabling inductance are minimized to deliver a clear path for maximum power.

The amplifier channels are thus able to deliver stable, continuous power at maximum output without affecting one another, even when driving the lowest impedances. While some amplifiers oscillate or run out of power when driving lower impedance loads, the STR Power Amplifier remains perfectly stable under all conditions.

A sequence-controlled soft turn-on significantly reduces power line transients and in-rush current during start up, thereby preventing accidental tripping of circuit breakers.
