JDS Labs Atom Amp+
Even more matter and even more substance, JDS Labs Atom+ has been conceived as the next-generation replacement to Objective2, and 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 6.35mm headphone jack, gold-plated preamp RCA outputs, and both 3.5mm and RCA inputs. Ample power. No noise. Front-mounted controls. Atom Amp+, the JDS Labs standard for performance and value in a headphone amp.
Atom Amp vs. Atom Amp+ – What’s New?
- Boosted performance using the same analogue integrated circuit employed in the matching Atom DAC+
- Custom matched potentiometers with superior low volume imaging of up to 20dB better than the original Alps potentiometers
- Upgraded input stage amplifier chips from NJM2068 to NJM5532 and small tweaks to supporting resistors
- Achieves 119dB signal-to-noise-ratio of approximately 6dB improvement
More than 1W of power into each channel allow the Atom Amp+ to be 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 full volume control for external devices via its RCA output. Atom Amp+ is the most advanced amplifier from JDS Labs achieving the highest performance levels for all analogue audio requirements.
Your new favourite amp and preamp.
Ultra High Power
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.
Preamp Outputs
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.
Smart Logic
Designed for desktop listening, Atom Amp+’s relay muting eliminates pops and thumps during startup.
Dual Gain
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+.
Top Performance
Atom Amp+ is JDS Labs’ most advanced analogue amplifier to date, achieving top performance from its 4-layer, star grounded layout.
