Offered is „GCT---------------Ground Circuit Transducer“ by Synergistic Research as second-hand device from the category „HiFi-Tuning-Accessory“ on audio-markt.de - the online market place for high-end. The advert with the number 3313255640 ends on 28.11.2026 at 13:37 o'clock.
Compared with buying a generic speaker accessory at €85, this Synergistic Research item is a strong bargain: the price sits well below the €348 25th-percentile mark from three recent comparable listings, versus a €611 median and €1,057 75th percentile. The exact model is not identified, so those figures are the safest benchmark, but on price alone it looks like a genuine buying opportunity.
Synergistic Research’s speaker accessories are generally aimed at refinement rather than basic function, with products ranging from speaker-cable treatments to HFT-style tuning devices and connectors. At €85 in good condition, the sensible check is model-specific: confirm precisely what is included, whether the required quantity is complete, and that fittings, adhesive, or connectors are intact. If it is a usable complete set, this is excellent low-risk entry pricing rather than a listing needing much negotiation.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
