Condition is unknown, but at US$459 this lands well below the US$544 25th percentile and far under the US$629 median for recent USD comps, so it reads as a strong deal on price. With only three comparables, the spread is tight, which makes the discount more meaningful rather than less.
The appeal here is the unit’s reputation as a serious digital/room-correction-era preamp: these were aimed at precise system control, and buyers usually want them for their flexibility, neutral handling, and niche status. At this price, the upside is straightforward if it powers up cleanly and includes the right extras; just confirm remote, power supply, and any required setup pieces, since missing accessories matter more on specialized gear.
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.
