At USD999, this KS112 asking price sits ambitiously high against the used market, where clean examples typically trade in the USD700-850 range—new ones still list around USD1,200, but gig warriors often drop to USD800 or less with some road rash. It's no steal unless pristine and low hours, but haggle toward USD850 if the cosmetic wear matches pro rental duty.
Before biting, power it up to confirm the Class D amp runs cool without fan whine or distortion, as those variable-speed fans and 2000W modules can falter from dust buildup. Verify all four low-noise casters roll smooth, the birch cab shows no port damage or water warpage, and both M20 pole sockets are intact—missing the warranty sticker means no 6-year coverage shot.
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.
