You guys may have seen some content around this late last night but the official launch is here!! The Atom Amp is now available Conceived as the next-generation replacement to Objective2, Atom Amp builds on more than a decade of amplifier design evolution at JDS Labs. We’ve streamlined the amp to include everything our customers have requested without additional configuration and cost. Atom Amp comes fully loaded with a smooth ¼” headphone jack, gold-plated preamp RCA outputs, and both 3.5mm and RCA inputs. Ample power. No noise. Front-mounted buttons. Atom Amp, our new standard for performance and value in a headphone amp. PREAMP OUTPUTS Unplug your headphones and Atom Amp’s knob adjusts volume of its RCA preamp outputs. 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. ULTRA HIGH POWER While most headphone listening demands only milliwatts, Atom Amp uses the same output buffers as our flagship Element Line, pushing >1W 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. TOP PERFORMANCE Atom Amp is our most advanced analog amplifier to date, achieving top performance from its 4-layer, star grounded layout.

Most of the time I strongly prefer this headphone with either my modded SET or my Vali 1, almost never listen to it on solid state with the exception of my HM601 which... sounds like syrup. However line out from the 601 into the Atom is... quite nice! It really doesn't sound like it's there, that is to say it's quite transparent. So where as the Vali 1 and even the hm601s crapola opAmp sound hazy, with the Atom there's clarity, so no haze but there's still a very natural timbre but without any... noise If that makes sense. To further elaborate, I would NEVER feed the HM601 into the Vali 1. That would just be too messy, too... soft and "romantic" no thanks. Rather I feed straight from either my EL Dac or most of the time my NFB10ES2 reference system. How ever with the ATOM & HM601 I get a lot of similarities in tonality and detail even though the staging and imaging aren't quite as impressive. My point being, the amp neither adds nor takes away. It reminds me a lot of my Head Amp Pico Power. And to a lesser degree my iBasso PB2 which runs LME 49900s but in a fully balanced configuration. Now Switching to something nicer like a Soundaware P1, the P1 sounds... equally "not there" but there's detail the P1 pulls out that I don't get from the Atom, very fine transient information and staging cues that are just simply not present with the Atom. So I imagine, scaling up from the Atom Detail/Transient response/imaging or staging cues and even "plakton" are what a nicer amp will bring assuming your DACs not the bottle neck. An to further elaborate, while I feel the iBasso is tonally neutral, it's not entirely transparent. The iBasso in particular is... very authoritative. It typically brings an aggressiveness into what ever system I have it in. An the Soundaware P1... does but doesn't, I find the P1 again more clearly defines transient response, and even pulls out detail that the PB2 doesn't. So in a sense it's equally as impactful but without the perception of being "aggressive" that is to say it's Transparent. More to come of course!
