This is a strong deal at US$1,495: it sits below the recent comparable range’s 25th percentile of US$1,548 and well under the US$1,600 median. For a working, complete example, that pricing is genuinely attractive rather than merely fair.
The Modulus 3A is well regarded for its natural, spacious presentation, capable MM/MC phono stage, and minimalist dual-mono tube line stage. Its low-impedance design is relatively cable- and amplifier-friendly, while the separate power supply helps preserve dynamics and bass definition. The main thing to verify is tube condition: the four 6DJ8/6922s are consumables, and Audible Illusions recommends replacement roughly every 12–18 months depending on use. Confirm quiet operation, both channels, phono functionality, and that the power supply and correct cables are included.
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.
