With unknown condition, this is still a strong bargain at US$150 versus your recent comp set: it sits far below the US$663 25th percentile and well under the US$1,071 median. Even allowing for the usual caution on vintage gear, the asking price is low enough that it’s priced like a project or quick flip rather than a fully vetted, ready-to-use piece.
As a buy, the upside is straightforward: this is the kind of older integrated amp that can offer solid, straightforward two-channel utility if it’s healthy, and the matching-tuner stack adds some collector appeal. At this level, the main thing to confirm is basic functionality—clean controls, stable operation, and whether it powers up properly—because the price already leaves room for service if needed.
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.
