This is a buyer’s market for this category at the moment: with a median of US$1,071, the asking price of US$200 sits far below the US$663 25th percentile, so it reads as a strong bargain rather than merely a fair deal. At this level, the price is low enough that even a modestly good-condition stack can make sense on value alone.
The appeal here is the usual Stack Audio strength: a compact, well-matched DAC + tube headphone amp bundle with the stacker, which is the kind of setup that can deliver an easy, listenable presentation without a lot of fuss. For a buyer, the upside is maximizing value from an already bundled system; the main thing to verify is simple completeness and that both units power up cleanly, since the price is low enough that any missing accessories or functional issue matters more than usual.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Stack Audio, a British hi-fi manufacturer founded in 2013 and based in Devon, emerged from the vision of Theo Stack, who spearheaded its debut product, the Onset network streamer. Drawing on the UK's deep-rooted expertise in audio engineering, the company has since prioritized meticulous design and domestic production, earning international acclaim for products that embody uncompromising build quality and sonic purity.
The brand focuses on source optimization and system enhancement, specializing in vibration isolation and noise reduction solutions rather than traditional amplifiers, speakers, or turntables. Key offerings include the Serene record mat and stabilizer for turntables, AUVA EQ isolators for equipment and speakers, and earlier streamers like the Onset, Serene, and Link. These components employ machined aluminum enclosures, inert materials, and targeted interventions to eliminate jitter, microphony, resonance, and electrical interference, unlocking a system's full musical potential.
Positioned as a niche boutique player in the high-end market, Stack Audio commands respect among discerning audiophiles for its no-compromise engineering and exceptional value. Free from hype, its products deliver transparent, natural sound that elevates existing setups, fostering a growing reputation for innovation in subtle yet transformative upgrades.
