Densen

Densen Audio Technologies is a Danish hi-fi amplifier manufacturer founded by Thomas Sillesen in 1988-1993 (sources vary) in Esbjerg, Denmark. Sillesen built his first amplifier at age 13 and founded the company to create better audio products than those he was distributing. Known for their innovative zero-feedback amplifier technology, which Densen is virtually the only company in the world to use. The first product was the DM-10 integrated amplifier that debuted at the London HiFi Show in 1992. In 2021, the company was acquired by Casper Reinhold (45-year-old engineer from Aalborg) and Ditlev Leth (23-year-old DTU electrical technology student), who established Densen Audio ApS. Production continues in Denmark maintaining the 100% Danish brand heritage.
