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.

We have arrived at the golden age of headphone amplification folks. What JDS Labs Atom delivers for just $99 is astonishing. Performance is without fault. Plenty of power is available for even high impedance headphones like Sennheiser HD-650. We are talking clean, clean, power.

Audio Science Review The Atom, November 2018

Atom is clean and precise. It outperforms the price tag and it comes as no surprise to say that it is my personal recommendation for a neutral, balanced amplifier at a low budget.

Headfonia Reviews JDS Labs Atom Amp, January 2019

Unplug your headphones and Atom Amp's knob adjusts volume of its RCA preamp outputs, so that you can control volume of your powered speakers.


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.


While most headphone listening demands only milliwatts, Atom Amp uses the same output buffers as our flagship Element Line, pushing 1W of clean audio per channel.


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


Low gain of 1.0x is well suited to driving efficient IEMs, while high gain easily powers demanding full size sets when paired with a 2VRMS DAC.


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