We built Atom Amp 2 for those who demand more. Atom Amp 2 is like Atom Amp+ on steroids. It's housed in an aluminum chassis with an easier to grip knob, featuring both 4.4mm and 6.35mm headphone jacks, failsafe DC protection, and octo-buffers pumping out more than twice the power of Atom Amp+. No noise. Front-mounted controls. Hand matched potentiometers. Custom engravable. Atom Amp 2, your new go-to headphone amp.
I honestly think that every audiophile should have a no-frills Atom 2 Amp on their desk. It’s simply that good.
You get an essentially flawless, state of the art headphone amplifier in the form of Atom 2. [. . .] Really, I can't think of anything negative to say even though I am good at that sort of thing!
