Angeboten wird „EVO3 Sigmas“ von IsoTek Power Systems Ltd. als Gebrauchtgerät aus der Kategorie „Netzleisten“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 7800651926 endet am 27.07.2026 um 09:44 Uhr.
This is overpriced versus the recent used market: €1,850 sits well above the €1,546 75th percentile and roughly €650 over the €1,200 median, so it reads ambitious rather than fair.
That said, the Sigmas is a respected mains conditioner in a serious system, with a strong reputation for lowering noise floor, tightening bass, and giving digital front ends and source-heavy rigs a cleaner, calmer presentation. If it’s genuinely in good condition, with no damage, all original packing, and a seller who can confirm clean use history, there’s still upside for someone who specifically wants this level of power treatment—but at this asking price I’d expect excellent provenance or extras to justify the premium.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
