Conceived as the next-generation replacement to Objective2, Atom Amp builds on more than a decade of amplifier design evolution at JDS Labs. We've streamlined the amp to include everything our customers have requested without additional configuration or cost. Atom Amp comes fully loaded with a smooth 1/4" headphone jack, gold-plated preamp RCA outputs, and both 3.5mm and RCA inputs. More power. No noise. Front-mounted controls. Atom Amp, our new standard for performance and value in a headphone amp.
