A US$400 asking price lands above the median but still well below the 75th percentile of the recent comparable pool, so it reads as fair-to-strong rather than inflated. It is not a bargain at the 25th percentile level, but it is also not an ambitious ask for a niche, modded Drop piece with a known upgrade path.
What makes it worthwhile is the appeal of a Burson op-amp upgrade: these are usually sought by buyers who want a cleaner, more refined presentation without jumping to a whole new component. If the unit is complete, working properly, and the install was done cleanly, that kind of upgrade can be a nice shortcut to a more resolving sound and better resale appeal. At this price, I’d mainly want confirmation of the exact configuration, who did the work, and whether the original parts or packaging are included.
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.
