Allmänt erkänd som en av de bästa strömförsörjningarna. Köp av mig direkt av Alex Crespi. Tillverkas för hand i små serier. Numer ersatt av den dyrare modellen JS-4. Inkluderar den 1,5 m DC-kabel med Oyaide-kontakter som ingick i början. Kan skickas i originallåda. Priset är fast.
Against your recent SEK comps, kr 6,000 is clearly ambitious: it sits well above the 75th percentile of kr 4,821, versus a median of kr 3,010 and a 25th percentile of kr 2,843. For a used listing, that means the asking price is asking for a premium that the current comparable market does not really justify.
That said, this is a respected power supply in hi-fi circles, and buyers usually chase it for cleaner, more stable delivery and the audible gains that can bring to a streamer, DAC, or networked source. If it is complete, quiet, and truly well cared for, the value is in its versatility and reputation—but at kr 6,000, I’d want strong condition, original accessories, and a convincing reason to pay above the recent market.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
UpTone Audio emerged from the U.S. audio engineering scene, with products rooted in the circuit designs of John Swenson, a veteran chip designer with decades of experience at a major integrated circuit firm. Produced entirely in the USA, the brand emphasizes meticulous testing and a two-year warranty on each unit, reflecting a commitment to reliability born from Swenson's expertise in digital and analog technologies.
The company specializes in niche upgrades for computer-based audio systems, including devices like USB regenerators, power supplies, and accessories that enhance digital playback. Rather than traditional categories such as amplifiers, speakers, or turntables, UpTone focuses on targeted components—linear power supplies, network renderers, and clocking solutions—that address bottlenecks in streaming and DAC performance, all engineered for measurable sonic gains.
Positioned as an affordable boutique player in the high-end market, UpTone earns praise among discerning audiophiles for delivering real, audible improvements without hype or "snake oil." Its products occupy a sweet spot for serious listeners upgrading Roon or Tidal setups, fostering a loyal following through technical integrity and engagement on forums like Audiophile Style.
