JDS Labs Atom Amp 2

The JDS Labs Atom Amp 2 is designed for listeners who demand more from their headphone amplifier. As the successor to the Atom Amp+, this second-generation model features a sleek aluminum chassis with an ergonomic metal knob, two headphone outputs (4.4mm and 6.35mm), and robust DC protection. At the heart of the Atom Amp 2 are octo-buffers that deliver over 2600 mW (2.6 W) per channel, completely clean and distortion-free—all with an exceptionally low noise level. With front-panel controls, hand-selected potentiometers, and support for personalized engravings, the Atom Amp 2 is the ultimate amplifier for everyday use.

Key Features

Metal Chassis

The Atom Amp 2 is housed in a durable, anodized aluminum chassis that combines strength and elegance. The textured metal knob offers a better grip, and the housing can be personalized with free laser engraving, allowing users to add text or artwork of their choice.

Power to Spare

Although most headphones require only milliwatts, the Atom Amp 2’s octo-buffer delivers over 2.6W per channel, allowing it to effortlessly drive both sensitive IEMs and demanding full-size headphones.

Dual Inputs, Dual Outputs

The Atom Amp 2 functions as both an amplifier and a preamplifier and accommodates two sources, allowing you to easily switch between 3.5mm and RCA inputs with the push of a button. The front panel features both 6.35mm and 4.4mm headphone outputs for maximum flexibility.

Preamp Outputs

When the headphones are disconnected, the volume control automatically switches to the RCA preamp outputs, allowing for easy volume control of active speakers.

Dual Gain Settings

The Atom Amp 2 offers a low gain of 1.0x—precisely tuned with hand-selected potentiometers—for efficient IEMs, while the high gain effortlessly drives demanding headphones, especially when paired with the 2 VRMS Atom DAC 2.

Exceptional Performance

Thanks to a 4-layer, star-grounded PCB design and octo-buffer technology, the Atom Amp 2 achieves the lowest noise level of any Atom amplifier to date, ensuring absolute transparency and high-quality audio performance.
