Here is the excellent Element IV Headphone Amp and DAC by JDS Labs.Included are the USB cable, original box, and power supply.
This is a buyer’s market for this category, and this asking price is ambitious: at US$450, it sits well above the US$191 75th percentile and far over the US$127 median for recent used comps. That doesn’t make it impossible, but it does mean you should only pay up if the condition, cosmetic state, and included accessories are unusually strong.
What makes it worth considering is the reputation of this line for clean, powerful desktop performance, with the kind of transparent DAC/amp sound that pairs well with demanding headphones and a simple all-in-one setup. If it’s truly in excellent condition with the original power supply and cables, that helps, but at this price I’d still want a notably clean, complete listing rather than just “works.”
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
JDS Labs emerged in 2007 from the college bedroom of founder John Seaber in the United States, sparked by frustration with his iPod's weak headphone drive and lackluster bass. Seaber, now a BSEE holder from Missouri S&T and lead engineer, hacked an open-source cMoy amplifier design, adding a bass boost and selling it on eBay as the cMoyBB—marking the brand's scrappy debut. From basement operations in Collinsville, Illinois, it scaled rapidly, adopting the influential Objective2 amplifier in 2011 and expanding with in-house CNC machining to meet surging demand.
The brand specializes in high-fidelity headphone amplifiers and digital-to-analog converters (DACs), delivering objectively neutral sound without audiophile premiums. Early portable models like the C421, C5, and C5D evolved into stacked desktop rigs such as the Atom and Element series, optimized for driving demanding headphones. Direct-to-consumer sales from their Illinois facility ensure competitive pricing, with no retail markups, alongside robust two-year warranties and meticulous U.S. assembly.
JDS Labs commands respect in the mid-tier hi-fi market as a benchmark for measurable performance and value, powering enthusiasts' setups worldwide. Its "science-first" ethos—prioritizing transparency over hype—has fueled triple-digit growth, cementing a niche as the go-to for reliable, no-nonsense amplification that punches above its weight.
