NuPrime is a small AMG STA power amplifier capable of delivering 300 watts at 8 ohms in bridge mode and 320 Watts at 4 ohms load. He achieves such indicators by using a clever scheme that combines two cascades – one in class A on JFET transistors and the second in class D. In traditional stereo mode, the power is 120 watts per channel at 8 ohms and 200 watts at 4 ohms.
