This is far above the recent used-market center of gravity: at US$2,631, it sits well beyond the US$914 75th percentile and more than 4× the US$637 median, so it reads as ambitious unless the listing includes unusually strong extras or provenance.
That said, the Studio Six has a real following for a reason: it’s a serious tube headphone amp with a big, smooth, spacious presentation that many listeners buy specifically for high-impedance dynamics and a more dimensional, “luxury” sound. If this one is clean, serviced, and comes with original accessories or low-use tubes, the upside is longevity and a less common enthusiast piece; at this price, though, I’d want clear evidence of condition, maintenance history, and what exactly is included.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Campfire Audio emerged from the legacy of ALO Audio, founded in 2009 by Ken Ball in Portland, Oregon. Building on ALO's reputation for premium audio cables, Campfire Audio launched as a dedicated in-ear monitor (IEM) brand in summer 2015 with its debut trio: Jupiter, Orion, and Lyra. Hand-assembled in their Portland workshop, the brand embodies American craftsmanship, drawing inspiration from the Pacific Northwest's landscapes in its distinctive faceted metal shells.
The company specializes exclusively in high-end wired IEMs, eschewing amplifiers, speakers, or other categories. Their lineup spans over 45 models since inception, featuring multi-driver balanced armature designs like the iconic Andromeda—first released in 2016 with five drivers for a natural, expansive soundstage—and evolutions such as the ten-driver Andromeda 10. Precision tuning and material innovation define their approach, catering to diverse sound signatures.
Campfire Audio commands a elite position in the boutique IEM market, revered as a top-tier innovator for audiophiles seeking reference-level detail and aesthetics. Standouts like Andromeda and Trifecta have cemented their status among the world's finest, with unwavering build quality and performance earning trust from discerning hi-fi enthusiasts worldwide.
