At A$320, this Zero Zone Dual LPS listing is priced at the top of the typical used range for quality dual-output linear supplies, making it an ambitious ask rather than a bargain. While genuine high-end linear units often land between A$200 and A$280 on the used market, this specific listing matches the price of a new equivalent found overseas (around A$420 after conversion from US$275), so the value hinges entirely on the "Excellent" condition and local availability.
The Zero Zone Dual LPS is well-regarded for delivering ultra-low noise and stable 12V/24V outputs, a significant upgrade for sensitive audio gear that benefits from clean linear power. Buying local at this price offers immediate access without import hassles or warranty risks, and the excellent condition suggests it’s been well-maintained by an original owner. If the unit includes original cables and packaging, this becomes a solid opportunity to step into reliable linear power without the premium of importing new.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Dual emerged from the Black Forest region of Germany in 1907, when brothers Christian and Joseph Steidinger began manufacturing clockwork and gramophone components in St. Georgen. The company adopted its now-iconic name in 1927 after pioneering dual-mode power supplies that allowed gramophones to operate from either mains electricity or mechanical wind-up mechanisms. This innovation marked the beginning of Dual's transition from component supplier to full-fledged audio manufacturer, establishing a foundation of engineering precision that would define the brand for decades.
Dual built its reputation primarily as a turntable specialist, becoming Europe's largest turntable manufacturer by the post-war era with over 3,000 employees across multiple factories. Beyond vinyl playback, the company expanded into cassette players, CD players, and broader consumer electronics throughout the 1970s and 1980s, demonstrating versatility across analog and digital formats. The company's focus on mechanical excellence and stable drive systems earned it recognition as a dependable, quality-focused manufacturer throughout its European heyday.
Today, Dual occupies a fragmented market position following corporate restructuring in the 1990s and subsequent ownership changes. The original German turntable line continues production in St. Georgen under Alfred Fehrenbacher GmbH, maintaining traditional manufacturing standards and appealing to vintage enthusiasts and collectors. Separately, Namsung Electronics markets Dual-branded consumer electronics in the Americas at accessible price points. The brand's legacy rests primarily on its classic turntables, which remain highly sought after by collectors and audiophiles valuing precision engineering and heritage craftsmanship.
