For Sale:I am selling the very good Auva 70 speaker isolators (a set of 8 - 4 for each speaker). I am the original owner and have owned them since 2023.

New, Stack Audio AUVA products sit in premium territory, so A$750 for this used listing is not a bargain but it is still workable if the condition and included bits are solid. Against the recent used AUD comps, it lands well above the A$245 median and also above the A$497 75th percentile, so this is clearly an ambitious ask rather than a fair-market steal.
What keeps it interesting is the AUVA’s reputation as a genuinely serious isolation/decoupling upgrade, with the kind of audible refinement that can be hard to un-hear once it’s in a system. If the set is complete, lightly used, and the seller can show careful ownership, there’s real upside here for someone chasing a meaningful system tweak. I’d only press for details on fit, model variant, and included accessories before paying this much.

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.
