About the DH200

The Hafler DH-200 is a stereo power amplifier kit designed in the 1970s, delivering 100 watts per channel into 8 ohms. It uses 26 transistors, 8 MOSFETs, 24 diodes, 4 zener diodes, and a diode bridge, featuring a fully complementary, symmetrical push-pull circuit that is direct coupled throughout except at the input. The amplifier is known for its extremely low distortion (0.012% THD), high damping factor (50), and wide frequency response (10Hz to 40kHz). It includes protective features such as AC line fuse, B+ fuses, thermal breakers, and speaker fuses inside the feedback loop to maintain sound quality. The DH-200 is regarded as a high-performance, reliable, and affordable amplifier from the pinnacle era of home HiFi, with a warm sound signature and solid build quality. It weighs 26 lbs and measures 5-1/8 x 16 x 10-1/2 inches. The amplifier is no longer in production but remains highly respected among audiophiles.
