This A$1,900 asking price for the Audible Illusions Modulus 3 in excellent condition is ambitious, sitting well above the 75th percentile of A$1,634 for recent AUD listings and far past the median of A$1,138. While the “excellent” condition note implies a clean, well-maintained unit that justifies a premium over battered examples, the price still exceeds the top quartile of the market by nearly A$266, making it a stretch for a buyer seeking fair value in today’s used market.
The Modulus 3 remains a cult favorite for its warm, musical tube sound and exceptional headphone amplification, offering a rich, organic texture that many modern amps lack. Its rarity and original-owner condition can be meaningful upsides, especially if it includes the original power supply and cables, but at this price point, a buyer should verify the presence of all accessories and confirm the tubes are healthy or easily replaceable to justify the premium.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Audible Illusions was founded in the late 1970s by three Silicon Valley engineers—Bruce Moore, Tom Taylor, and Alan Priestly—establishing itself as a pioneering force in high-end audio design. The company has operated for over forty years, building a reputation as a major contributor to the development of premium audio components. Based in California, Audible Illusions has maintained its independence and vision throughout decades of industry evolution.
The brand is primarily known for preamplifiers, particularly its flagship Modulus series, which has achieved remarkable market penetration with more than 19,000 units sold since 1981. Audible Illusions distinguished itself as a pioneer in modern single-ended tube design during the early 1980s, when most competitors still relied on conventional approaches. The company's preamps are recognized for their refined signal path and sonic characteristics, appealing to discerning listeners who prioritize audio fidelity.
Audible Illusions occupies a firmly high-end, boutique position within the audio market, catering to experienced enthusiasts and collectors who value heritage and sonic performance over mass-market accessibility. The brand's longevity and the sustained demand for its products—particularly vintage Modulus preamps in the secondary market—underscore its credibility among serious audiophiles. While the company maintains a relatively low public profile compared to larger manufacturers, its influence on tube preamplifier design and its loyal customer base reflect its significance within premium audio circles.
