Its age matters only in the sense that this is an established, older installation-oriented design rather than a current high-feature integrated amp. At US$69, though, timing is excellent: it sits below the US$80 25th-percentile mark and well under the US$160 median from 427 comparable listings, making this a genuine bargain if the test claim is accurate.
The AMP 100 is a practical, well-regarded workhorse: 50 watts per channel into 8 ohms, dual inputs, auto signal-sensing power-up, A/B speaker switching, and the ability to run bridged for more output. It suits a second system, distributed audio, or an easy speaker-driving duty better than a last-word audiophile setup. At this money, “tested” is meaningful upside; just confirm both channels are clean, the input switching works, and the speaker terminals and controls are noise-free.
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.
