Offered is „XACT N1 Audiophile Network Switch“ by Various / Other as exhibit from the category „Digital-Accessory“ on audio-markt.de - the online market place for high-end. The advert with the number 4296871500 ends on 25.10.2026 at 09:01 o'clock.
At €3,200, this sits well above the typical used market for this category and looks ambitious rather than fair. Against a median of €970 and even a strong upper-quartile level of €2,425, the asking price leaves a lot of room for negotiation unless there’s exceptional provenance or a notably upgraded package.
That said, network-switch tweaks have a real following in serious digital setups, and the appeal here is usually in cleaner timing, lower noise, and a more refined presentation rather than night-and-day transformation. If it’s truly clean, complete, and comes from a careful owner with original packaging or useful accessories, it can still make sense for a buyer already committed to this approach—but at this price, documentation and condition need to be excellent.
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.
