Conceived as the next-generation replacement to Objective2, Atom builds on more than a decade of amplifier design evolution at JDS Labs. Atom Amp+ tops the award winning Atom Amp with hand matched potentiometers and even higher performance, and comes fully loaded with a smooth 1/4" headphone jack, gold-plated preamp RCA outputs, and both 3.5mm and RCA inputs. Ample power. No noise. Front-mounted controls. Atom Amp+, our 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

It is hands DOWN a breathtaking unit to listen to and it unquestionably sets a new standard for what's possible from a $99 Amplifier!

Mshenay on JDS Labs Atom Amp, November 2018

The Atom line is focused on sheer performance and performance only. JDS aimed for a no-BS amplifier that is easy to operate, hella powerful, and compact. Under hundred dollars, it was crazy at the end of 2018, it is still crazy in 2021.

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.


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. We avoid the marketing race to overkill power in order to keep Atom's power supply reasonably sized.


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.


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


Low gain of 1.0x with hand matched potentiometers are well suited to driving efficient IEMs. High gain easily powers demanding full size sets when paired with the matching 2VRMS Atom DAC+.


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