Angeboten wird „QSA Feinsicherungen und Sicherungshalter“ von QSA als Neugerät aus der Kategorie „Zubehör“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 9580884540 endet am 31.08.2026 um 19:09 Uhr.
This is a strong deal. At €178, it sits well below the €540 25th percentile of recent comparable used listings and far under the €902 median, so it’s priced like a bargain rather than a merely fair ask. For a small-value speaker item, that’s exactly the kind of listing worth moving on quickly if it’s genuinely in good working order.
QSA pieces are typically bought for their compact, high-quality execution and the “serious audio” feel they bring at the small-speaker end of the market. At this price, the upside is simple: if the drivers, cabinets, and any crossovers are healthy, you’re getting an easy entry point into a respected niche brand with very little downside. I’d just confirm there’s no damage, distortion, or missing key parts before jumping.

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.
