Should you pay US$1,299 when the recent comp median is US$628 and even the 75th percentile is only US$628? No—this is clearly ambitious, sitting at more than double the top of the recent comparable range, so I’d want a very strong reason to justify it.
That said, this is a serious piece of kit: TACT’s RCS units are admired for precision control, flexible digital processing, and the sort of transparent, high-resolution sound that can elevate a revealing system. If the unit is fully functional, complete, and well cared for, the upside is real—but at this price, I’d only move if it includes extras, documentation, or some unusual provenance that materially sweetens the deal.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
TACT Audio emerged in the late 1990s as a pioneering force in digital amplification, debuting the Millennium at the 1997 Stereophile Show as the world's first true digital amplifier using pure Pulse Width Modulation (PWM) technology. This Danish innovator quickly gained attention for bridging digital signal processing directly to loudspeakers, minimizing analog conversion losses. While a separate Chinese entity, TACT Pro Audio, launched in 2013 focusing on professional speakers and systems, the hi-fi brand's heritage centers on its early breakthroughs in high-resolution audio electronics.
The brand specializes in cutting-edge digital amplifiers like the renowned Millennium series, including models such as the 2150 and 216, alongside stereo digital preamplifiers like the 2.2x with dynamic room correction supporting up to 96kHz/24-bit PCM. Their lineup emphasizes PWM amplification and innovative DSP for precise sound reproduction, targeting audiophiles seeking digital purity over traditional analog designs. Speakers and related pro audio gear appear in later iterations, but TACT's core strength lies in amplification and correction tech.
Positioned as a niche high-end boutique in the hi-fi market, TACT commands respect among knowledgeable buyers for its trailblazing digital innovations, though its visibility has waned amid service complaints and apparent dormancy. Collectors and digital amp enthusiasts prize vintage Millennium units, while the brand's forward-thinking approach continues to influence modern Class D designs.
