Please review pictures. AMP (From Manufacturer) YOUR NEW FAVORITE AMP + PREAMPConceived as the next-generation replacement to Objective2, Atom 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 1/4 headphone jack, gold-plated preamp RCA outputs, and both 3.5mm and RCA inputs. Ample power. No noise. Front-mounted controls. Atom Amp+, our standard for performance and value in a headphone amp. FEATURES PREAMP OUTPUTSUnplug your headphones and Atom Amp+s knob adjusts volume of its RCA preamp outputs, so that you can control volume of your powered speakers. ULTRA HIGH POWERWhile 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 Atoms power supply reasonably sized. DUAL INPUTSAtom 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. HEVI OR STANDARDChoose the HEVI enclosure for maximum style, with a larger aluminum knob and a thick, anodized aluminum top surface. Or choose Standard for maximum value. See dropdown menu above for details! DUAL GAINLow 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 PERFORMANCEAtom Amp+ is our most advanced analog amplifier to date, achieving top performance from its 4-layer, star grounded layout.

UPGRADEABLE FIRMWAREAtom DAC+s XMOS based firmware configures and manages all functionality, with DFU support for future updates. UAC2 AND UAC1Atom DAC+ supports up to 32/384kHz PCM over a custom XMOS XU208 based UAC2 engine.

Doing duty at my office desk. Used yes, but works and sounds great. Comes with power supply and boxes. Selling because I upgraded.

Excellent budget Amp and DAC stack. I was using with my Sennheiser HD 600 that I am also selling. All were purchased this year. I have decided to upgrade my whole setup. I was using a pair of powered Audioengine A2+ powered speakers and an iMac and they sound amazing with this stack! Includes original boxes and packaging swell as the power adapters in their boxes. I combine shipping if you want the headphones too. These have been really well taken care of and I have never had an issue with them. Paid full price just a few months ago. I will combine shipping at a reduced cost if you buy additional items from me - just ask! I try to be very accurate with descriptions and have 100% feedback. All items are sold as-is. I’m no expert grading vinyl, I just use my previous purchases as a guide. I don’t play test to see if there is any warping.
