Angeboten wird „SDR-4000 S“ von Spectral Audio als Gebrauchtgerät aus der Kategorie „CD Player“ bei audio-markt.de - dem Online-Marktplatz für High-End. Das Inserat mit der Nummer 6507869097 endet am 13.09.2026 um 06:02 Uhr.
Spectral’s SDR-4000 is a revered, limited-edition reference CD processor that culminates the brand’s high-resolution digital program. At €7,950, this asking price sits near the median of the typical used market for the SDR-4000SV, where listings often range from €4,900 to €9,300, making it a fair but not bargain valuation.
This unit is a worthwhile buy because the SDR-4000SV is legendary for its silky transparency, ultra-low jitter (1 picose RMS), and fully discrete, passive analog design that delivers DC-to-22kHz response with <0.001% distortion. Its rarity, original-engineering pedigree, and time-critical value for collectors seeking a true reference player make this a compelling opportunity—especially if it includes original accessories and shows in good condition.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Spectral Audio, an American high-end audio brand, traces its origins to 1975 when Richard Fryer founded the company in pursuit of unparalleled musical realism. Initially sparked by Fryer's collaboration with partner Damian Martin to create a reference amplifier for Sound Advice in 1976, the venture evolved into Spectral Incorporated with the launch of the landmark MS-One amplifier in 1977 or 1978. Fryer enlisted the expertise of Dr. Keith O. Johnson, a legendary recording engineer and circuit designer renowned for innovations in analog and digital audio, including early advancements in cassette duplication.
The brand focuses on premium electronics, particularly power amplifiers, preamplifiers, and digital source components like state-of-the-art DACs, designed to integrate seamlessly as a unified system. Spectral eschews mass production, building limited quantities of each product to push performance boundaries without regard for cost constraints, treating development like an independent research lab rather than a conventional business.
Spectral holds a niche boutique position in the high-end market, revered by discerning audiophiles for its timeless engineering and refusal to chase trends, reviews, or aggressive marketing. Operating almost as a well-kept secret for over four decades, it prioritizes sonic purity and system synergy, appealing to serious listeners who value substance over hype.
