Two-Channel Revolution.
The All New STR Power Amplifier
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.
Imagine doling out 400 Watts/channel into 8 ohms
(both channels driven). Now visualize a massive
600 Watts/channel into 4 ohms, and an astonishing
800 Watts/channel into 2 ohms! The STR Power
Amp delivers true no-holds-barred performance.
Packed with 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, highly
conductive audiophile connectors provide a
perfect match to the STR Preamplifier.

• Sixteen bipolar output devices per channel
• Dual Mono Design
• Massive toroidal transformers
• Soft turn-on
• Four power on/off options
• No rail fuses
• Advanced Load Monitoring™ Technology
• Graphic front panel display for the power meter,
status, and easy setup navigation
