JDS Labs Atom

Refurbished unit in excellent condition repackaged with original accessories or accessories from compatible models and brands.

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.

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.
