About the 100.2

The Audio Research 100.2 is a solid-state stereo power amplifier introduced around 1998, rated conservatively at 100 watts per channel into 8 ohms, with the ability to deliver 200 watts into 4 ohms and 360 watts into 2 ohms, providing ample power to drive demanding speaker loads. It features a frequency response of 20Hz to 20kHz, a gain of approximately 26.5 dB, and an input sensitivity of 1.3V. The amplifier is praised for producing a detailed and natural sound with crisp highs, realistic midrange timbres, and tight, punchy bass, creating an impressive 3-D soundstage without the grain or harshness sometimes associated with solid-state designs. However, some technical reviews note relatively high distortion and noise levels due to its low feedback design, which affects its performance and thermal stability, making it less recommended from a purely measurement-based perspective. The unit measures 480 x 133 x 302 mm, weighs about 15.8 kg, and was originally It remains a respected amplifier for its musicality and power delivery despite some technical compromises.
