    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.

    PREAMP OUTPUTS
    Unplug your headphones and Atom Amp’s knob adjusts volume of its RCA preamp outputs. Control volume of your powered speakers.

    DUAL INPUTS
    Atom amp consolidates the need for a separate amp and preamp. Connect up to two sources and select between 3.5mm and RCA input with the push of a button.

    ULTRA HIGH POWER
    While most headphone listening demands only milliwatts, Atom Amp uses the same output buffers as our flagship Element Line, pushing >1W per channel.

    SMART LOGIC
    Designed for desktop listening, Atom Amp’s relay muting eliminates pops and thumps during startup.

    DUAL GAIN
    Low gain of 1.0x is well suited to driving efficient IEMs, while high gain easily powers demanding full size sets.

    TOP PERFORMANCE
    Atom Amp is our most advanced analog amplifier to date, achieving top performance from its 4-layer, star grounded layout.
