Angeboten wird „SL 10“ von Threshold als Gebrauchtgerät aus der Kategorie „Transistor-Vorverstärker“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 3942655879 endet am 03.10.2026 um 11:28 Uhr.
This lands just below the median for recent EUR comparables, so it reads as fair to mildly favorable rather than a steal. With only a €28 gap to the median and sitting between the 25th and 75th percentiles, the asking price looks well aligned with the local used market rather than ambitious.
That timing matters because older Threshold pieces are bought for the sound and the build, not for chasing the latest replacement model. A clean, good-condition SL-10 is appealing for its serious turntable engineering, stable speed, and the kind of long-term sonics that still make sense if the arm, suspension, and automation are intact; at €1,450, a well-kept example is a sensible buy if it’s complete and has been serviced.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Threshold Audio emerged in Sacramento, California, in 1974, founded by renowned audio engineer Nelson Pass alongside graphic designer René Besne and Joe Sammut. Pass, a pioneer in amplifier design, launched the brand with the groundbreaking Threshold 800A power amplifier in 1975, introducing a novel sliding bias system that boosted Class A efficiency while employing 48 output transistors in a sophisticated triple-series/triple-parallel configuration. This California-rooted heritage defined Threshold as an innovator during its original run, which spanned until the mid-1990s, after which the intellectual property changed hands, including a 1994 acquisition by investor Randy Patton, who integrated it with PS Audio and relocated operations to Camarillo.
The brand focused squarely on high-end amplification, producing iconic power amplifiers like the 400A and 800A, the Stasis series renowned for their balanced Class A performance, and preamplifiers such as the NS10, SL10, and FET range including the FET-1, FET-2, FET-9, and FET-10. Later designs, like the T-200 by engineer Michael Bladelius, continued this legacy. Threshold eschewed speakers, turntables, DACs, headphones, or cables, concentrating instead on pure analog amplification that prioritized sonic purity and robustness.
Threshold holds a revered position as a vintage high-end icon, cherished by collectors and audiophiles for its enduring sound quality and Pass's technical wizardry. Once a market leader in premium solid-state gear from 1975 to 1992, it remains a sought-after name in the used market, embodying boutique excellence rather than mass production, with modern revivals under Threshold Audio sustaining its elite reputation.
