Offered is „Entreq Eartha Apollo Erdungskabel 1,65 m mit USB A“ by Entreq as second-hand device from the category „Ground wire“ on audio-markt.de - the online market place for high-end. The advert with the number 6103273160 ends on 08.11.2026 at 10:42 o'clock.
Good condition at €300 makes this look like a strong bargain against the recent used market: it sits well below the €495 median and even under the €300–€752 interquartile band’s midpoint, so the asking price is firmly on the buyer-friendly side. For a niche Entreq grounding cable, that’s exactly where a sensible used deal should land.
What makes it appealing is the usual Entreq appeal: these are sought after by listeners who want a quieter background and a bit more ease/space around the presentation, especially in resolving systems where grounding tweaks can pay off. At this price, a clean, complete example is the sort of low-risk experiment that can be easy to justify, especially if the USB A lead length suits your setup and the condition is genuinely as stated.
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.
