Details & Highlights

Product Highlights

    Nothing gets the party started faster than the sheer horsepower of your home theater's amplifier. And when it comes to building amplifiers whose performance exceeds anything else in their class, no other brand has more success stories than Sunfire. The latest and best example of this fact is our new flagship amplifier, the TGA–7401. As its name implies, this is a true 7–channel amplifier that offers a relentless 7 x 400 watt profile, earning it the title of Most Powerful amplifier in its class. But power of this stature without equally serious control translates into trouble waiting to happen. That's why Sunfire developed its exclusive Tracking Downconverter™ technology for the coolest, most reliable operation no matt er how hot the performance gets.
