STR POWER AMPLIFIER Two-Channel Revolution

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.

The All New STR Power Amplifier

Doling out 400 Watts/channel into 8 Ohms with both channels driven (450W single channel), a massive 600 Watts/channel into 4 Ohms (both channels driven) and 800W in 2 Ohms. The STR delivers true no-holds-barred performance.

Innovative Electronics

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, conductive audiophile connectors provide a perfect match to the STR Preamplifier.
