JDS Labs Atom

More matter and more substance, JDS Labs Atom headphone amplifier takes the helm as the new standard for audio performance at a budget price. Intended to take the place of Objective2, the Atom amplifier incorporates everything and more than the predecessor without raising the price. With more power, zero noise and extended connectivity the Atom Amp embodies the proud JDS Labs amplifier design evolution.

Atom Amp comes fully equipped with a smooth 6.35mm headphone jack, gold-plated preamp RCA output, and both 3.5mm and RCA inputs. With more than 1W of power into each channel, the Atom is more than capable of driving even the most power-hungry headphones with ease. Dual gain settings extend the ability of the Atom for use with highly sensitive IEMs as well as hard to drive headphones.

With no need for a separate amp and preamp, the Atom acts as volume control for external devices via its RCA output when headphones are not connected. Atom Amp is the most advanced amplifier from JDS Labs achieving the highest performance levels for all analogue audio requirements.

Power in your hands.


JDS Labs Atom


Preamp Output
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.

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.

High Power
While most headphone listening demands only milliwatts, Atom Amp uses the same output buffers as our flagship Element Line, pushing up to 1W per channel.

Smart Logic
Designed for desktop listening, Atom includes microprocessor controlled relays that completely eliminate pops and thumps during start-up.

Dual Gain
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.

First headphone amp was a used massdrop O2 from ebay, it broke one of the channels and was unrepairable by me re-soldering caps and what not, even diy specialists.

I brought this not expecting to get much out of my HD 600 I was happy with them even after they broke out of my iPod, but this... this amp does give me a bit more soundstage, everything sounds cleaner and cleaner. It's an insanely clean amp, even my brother who owns a £5k speaker system with a (Marantz HD-AMP1), said he can hear the cleanness of this amp's headphone output out of my high-end motherboard even (gigabyte H310-M), before my O2 went out with the ODAC, now i'm using a diy low-capacitance star-quad 3.5 to 3.5 mm from my pc into the atom and i'm extremely pleased with it, honestly I didn't think they could sound any cleaner. 5*
Clean, amplication for just over £100

I got this on the recommendations on ASR forums and from various Youtubers.

This small unassuming amp is very clean and neutral and won't colour your source. I have it connected to Khadas Tone Board, which makes for ace combination and is very dynamic and punchy sounding.

Listening to Tool's new album Fear Inoculum (flac 24bit/96) - "Chocolate Chip Trip" on high gain with my cheapo Koss KPH30i the drums pound with such visceral power and realistic slam that it feels like watching them live on stage - and yes I have seen them live.. That kick drum! Seriously..

Bare in mind the build quality is not all that (mostly plastic) though its sound is worth it. Pretty much endgame for me, now I just need some headphones to match the rest of my gear!

Superb sound shame about the build

The audio clarity and detail from this amp is superb for the money it costs, the two iinputs are very useful.
The biggest disappointment is the build quality, it is a plastic case using poor quality components, the volume control feels nasty this is my reason for the four stars.

Best bang for buck amp.
