Angeboten wird „Olympus“ von Entreq als Gebrauchtgerät aus der Kategorie „USB Kabel“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 8536812536 endet am 08.09.2026 um 14:27 Uhr.
At €1,700, this Entreq Olympus is ambitious, sitting well above the 75th percentile of €1,474 and just under the new Olympus 10 T’s €1,790 retail. The median for recent used EUR listings is €764, with the top quartile capping at €1,474, so this asking price demands strong justification in condition or accessories.
The Olympus is a respected grounding box that cleans up system noise and tightens bass by offering a low-impedance earth path, a role Entreq has refined across its lineup. If this unit is original-owner, in excellent condition, and includes its oak base or any upgrade plates, it becomes a credible buy for those chasing the Infinity-level performance without the $4,230 new cost. Otherwise, the price is hard to justify against the typical used market.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Entreq, a Swedish hi-fi innovator, traces its roots to 1999 when founder Per-Olof Friberg—a former farmer with a deep passion for music—began crafting solutions to elevate audio purity. From his rural background, Friberg evolved into a specialist designer, blending natural materials and audio alchemy to pioneer noise reduction techniques. Handmade at their Swedish facility since 2002, the brand embodies a commitment to uncompromised performance, drawing on two decades of boundary-pushing development.
The company focuses on niche accessories that transform energy in audio systems, slashing noise floors for more natural sound reproduction. Entreq is renowned for groundbreaking ground boxes, the original audio USB and network cables, DC power solutions, and specialized switches—innovations now emulated by others. Absent from mainstream categories like amplifiers or speakers, their lineup targets system optimization through unique connective processes and materials.
Positioned as a high-end boutique force, Entreq commands respect among discerning audiophiles for its distinctive, performance-driven ethos. Skepticism once greeted their grounding principles, but widespread adoption affirms their elite status in the ultra-premium market, where every component prioritizes unforced musical flow over convention.
