Audio Dynamics Corporation

Audio Dynamics Corporation (ADC) was a prominent HiFi audio manufacturer best known for its high-performance magnetic phono cartridges. Founded by Peter Pritchard in New Milford, Connecticut, USA, in the early 1960s, ADC played a significant role in the audiophile market during the height of vinyl's popularity. The company was later acquired by BSR in the late 1970s and continued operations until around 1985. ADC products, especially cartridges and equalizers, are still respected by collectors and enthusiasts for their innovation and build quality.
