Säljer en legendarisk Threshold SA/3 – ett äkta, renodlat Klass A-slutsteg konstruerat av hifi-legendaren Nelson Pass. En riktig pansarvagn som kombinerar den djupt organiska röstkroppen och magin hos äkta Klass A med en rå, bottenlös strömstyrka och ett järngrepp om basen som få moderna maskiner matchar. Byggd som en tank med massiva kylelement och påkostad konstruktion. Effekt: Klass A driver det mesta med full kontroll Fint vintageskick med tanke på åldern Tung pjäs (skicka
Fair ask. At kr 11,000, this sits below the typical current used asking level for the SA/3, which clusters around roughly kr 22,000 to kr 40,000 depending on market and condition, so it looks like a real buy if it’s complete and functional.
That’s a worthwhile price for a well-regarded Nelson Pass/Threshold class-A amplifier with a big, composed sound and real drive into difficult speakers. The upside here is strong if the unit is original, quiet, and unmodified, but with unknown condition I’d want confirmation on bias stability, channel balance, and any service history before jumping.
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.
