Are you looking for a clean, powerful headphone amp rather than a built-in DAC? At US$150, this is a strong deal: it sits below the US$155 median and well below the US$190 75th percentile for comparable used listings, while remaining comfortably above the US$127 25th percentile. In other words, the price is better than fair without looking suspiciously low.
The 789 remains well regarded for its transparent, exceptionally low-noise presentation, substantial power, three gain settings, and useful RCA/XLR inputs plus 3.5mm, 1/4-inch, and 4-pin XLR headphone outputs. Balanced operation offers especially generous headroom for demanding planar headphones, while the lower gain settings suit sensitive headphones and IEMs. Just remember that it requires a separate DAC or line-level source; confirm the original power supply is included and that every output and gain switch works.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Drop originated as Massdrop in San Francisco in 2012, pioneering a community-driven model that aggregated enthusiast demand to source and develop exclusive products directly from manufacturers. By bypassing traditional retail chains, it built a loyal following of over 7 million members through limited-time "drops" of unique gear, earning acclaim for delivering hard-to-find items at competitive prices. The brand rebranded to Drop in 2019, expanding into its own designs like the Drop SHIFT mechanical keyboard and wireless headphones, often in collaboration with names such as Sennheiser for audiophile-grade audio.
In the hi-fi realm, Drop specialized in headphones, DACs, amplifiers, and cables, alongside mechanical keyboards and gaming peripherals, with audio as a flagship category. Its approach emphasized user feedback to refine products, yielding sought-after collabs like the Massdrop x Sennheiser line, blending accessibility with performance for enthusiasts.
Drop held a niche position as a disruptor in the mid-tier market, appealing to savvy buyers seeking value-driven, community-vetted hi-fi without high-end premiums. Acquired by Corsair in 2023, it shifted toward gaming hardware before shuttering its core operations in March 2025, marking the end of an era for direct-to-consumer audio innovation.
