Our take
JDS Labs Atom headphone amplifier is by far, the best value for an entry - mid level audio amplifier. Based in St. Louis, US, JDS Labs products appeal to people who demand the best in audio. You are bound to be impressed!
"We have arrived at the golden age of headphone amplification folks. What JDS Labs Atom delivers is astonishing. Performance is without faulty, Plenty of power is available for even high impedance headphones like Sennheiser HD-650. We are talking clean, clean power. Needless to say, JDS Labs Atom gets one of my highest recommendations." Amirm, audiosciencereview

Product details
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 pre-amp. Connect up to two sources and select between 3.5mm and RCA input with the push of a button.
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.
Smart Logic
Designed for desktop listening. Atom Amp's relay muting eliminates pops and thumps during startup.
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.
Top Performance
Atom Amp is our most advanced analog amplifier to date, achieving top performance from its 4-layer, star grounded layout.
Package:
1 x Atom Amp
1 x 16VAC Power Adapter
