This is a strong deal: at US$200, it sits far below the recent comp median of US$1,071 and even under the US$663 25th percentile, which is exactly where bargain territory starts to show up. For a stackable DAC/amp bundle with the matching hardware, that’s the kind of spread that usually leaves plenty of room for a very low-risk buy if the unit is functional.
The appeal here is straightforward: Stack Audio gear is valued for clean, low-noise, enthusiast-friendly performance, and a bundled stack is especially convenient if you want a tidy desktop setup without piecing things together. The included stacker adds practical value, and at this price the upside is in getting a cohesive, ready-to-use system for a fraction of normal used-market levels. The only thing I’d verify before jumping is that both units power on, the DAC inputs work, and the tube amp is quiet with no hum or channel imbalance.
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.
