Densen Audio Technologies is a Danish hi-fi manufacturer; makers of the legendary BEAT B-100 and DM-10 integrated amps.
Their focus is on music and involvement -- listening to music should be fun. Since the very beginning in 1988 all Densen amplifiers are made using zero-feedback, which, according to Densen, results in "extreme transparency, detail level, soundstage and dynamics".
Their products are also notable for their slick design; black boxes with (usually) nothing but two large gold knobs in the front.
