Angeboten wird „The Main NF6020“ von Einstein als Gebrauchtgerät aus der Kategorie „Netzfilter“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 5413317672 endet am 03.07.2026 um 17:55 Uhr.
It's a buyer's market for used high-end audio like Einstein gear, with Eurozone residential prices up modestly (Q2 2025 index at 152.79, trending to 153.83 in 2026) keeping supply steady amid economic caution. At EUR 599 in good condition, this Main NF6020 is a screaming bargain—well below the EUR 1,493-3,577 range from 12 recent comparable EUR listings (median EUR 2,256), landing in deep discount territory for a model that typically holds strong resale value.
Before biting, verify the power supply's health—Einstein monos are prone to capacitor wear after 10+ years—and confirm both fuses, original manual, and any remote are included. Test for channel balance and hum on your own rig if possible, as NF6020s can develop subtle bias drift. Solid snag if it checks out.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Einstein Audio Components: Brand Overview
Einstein Audio Components was founded in 1988 in Bochum, Germany, by Volker Bohlmeier and Rolf Weiler, two audio specialists united by a shared vision of delivering the highest fidelity music playback. The company name itself reflects a clever play on Bohlmeier's surname and the famous physicist. After three years of meticulous development, Einstein introduced "The Amp" in 1990, an innovative solid-state integrated amplifier that immediately established the brand as a serious contender in high-end audio. The amplifier's purist design and exceptional sound quality earned widespread critical acclaim and numerous industry awards, becoming an instant classic that remains recognized among leading audio publications.
Einstein's product portfolio centers on premium amplification and signal processing components, with particular expertise in both tube and solid-state technologies. Beyond "The Amp," the company has developed acclaimed products including "The Tube" preamplifier (introduced in 1998) and "The Final Cut," a pair of tube monoblock power amplifiers released in 2002. The brand also manufactures cables and accessories, maintaining the same rigorous sonic standards applied to their primary components. Each device is handcrafted as a single unit and subjected to exhaustive testing until it meets Einstein's exacting acoustic specifications.
Einstein occupies a distinctly boutique position within the high-end audio market, representing the pinnacle of niche luxury manufacturing. The company's unwavering commitment to sonic purity over market trends, combined with its distinctive visual design language and meticulous German engineering, has cultivated a devoted following among audio connoisseurs worldwide. Einstein remains a small, independently operated manufacturer where sound quality alone determines component selection, positioning the brand firmly in the elite tier of audiophile equipment.
