Angeboten wird „Audiophile 645 Electrostatic Speakers“ von Sound Lab als Gebrauchtgerät aus der Kategorie „Standlautsprecher“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 6704722763 endet am 03.07.2026 um 01:18 Uhr.
Compared with the obvious alternative at this price point—another well-bought used electrostatic set—€15,000 is far above the typical market here. Against your own comp set, it sits well beyond the 75th percentile of €1,806, so this is an ambitious ask rather than a fair-market buy.
That said, this is a serious panel speaker for someone chasing the electrostatic thing: the speed, transparency, and image precision are the real draw, and a clean good-condition listing can still appeal if the package is unusually complete or the seller can document careful ownership. The main buyer question is value, not desirability; at this level I’d want strong proof of originality, service history, and included extras before treating it as more than a passion purchase.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Quantum Science Audio (QSA) emerged in early 2020 under the leadership of Steven Tsang, an electronic engineering expert with deep roots in audio consulting. Based in Scottsdale, Arizona, with ties to Hong Kong where Tsang honed his expertise, the brand quickly carved a niche through relentless innovation in power components. Drawing from over two decades of proprietary research, QSA embodies a fusion of technical discipline and audio obsession, prioritizing subtle yet profound system enhancements.
The company's focus centers on high-performance aftermarket fuses, including thermal, slow-blow, automotive, and specialized AC variants like inlets, outlets, and panel breakers. QSA also extends into power receptacles and related accessories, all engineered to eliminate so-called "bottlenecks" in signal paths. Their lineup spans accessible entry points at around $28 to ultra-premium models commanding exorbitant prices, reflecting escalating tiers of advanced materials and quantum-inspired treatments.
In the hi-fi market, QSA occupies a polarizing boutique position among high-end enthusiasts, celebrated by some for transformative sound improvements in power delivery. Top models attract audiophiles chasing marginal gains, though skeptics dismiss the claims as overreach amid long production lead times. This niche status suits discerning buyers open to experimental upgrades in an otherwise crowded field.
