About a/d/s

a/d/s (Analog and Digital Systems) is a historic HiFi audio brand founded by Dr. Godehard Guenther in 1972, based in Cambridge, Massachusetts. Initially known for importing and re-engineering Braun speakers and audio electronics from Germany, a/d/s developed a reputation through the 1970s and 1980s for their minimalist, high-fidelity speakers and distinctive sound quality. The company later expanded into the car audio market and changed its branding to 'A/D/S/'. After Dr. Guenther's retirement in the 1990s, a/d/s merged with Museatex and was later acquired by Directed Electronics in 2001, effectively ending its original manufacturing operations. The brand is now considered dormant, known mainly among enthusiasts for its vintage audio products.
