Celebre apparecchio progettato da Bob Carver, made in USA, diverse funzioni: Sonic Holography, il circuito più famoso, circuitazione "t" (Tube Transfer Function),autocorrelatore (Auto Correlator Noise Reduction),generatore di ritardo ambientale (Time Delay), doppio stadio phono evoluto: Dispone di ingressi separati dedicati sia alle testine MM (Magnete Mobile) che alle più pregiate MC (Bobina Mobile), con la possibilità di calibrare l'impedenza di carico per ottimizzare il suono del giradischi. Ottime condizioni estetiche, perfettamente funzionante, appena revisionato e testato in laboratorio, fornito di copia del manuale d'uso originale.
At US$817, this is well above the used-market median of US$350 and even past the 75th percentile at US$536, so it reads as ambitious unless it’s exceptionally clean, fully serviced, and complete. For a buyer, that means the value case has to come from condition and provenance more than price alone.
That said, this is a respected vintage Carver preamp with the kind of sonic-holography-era appeal enthusiasts chase, and clean examples can still draw interest. If it’s original, functioning properly, and includes the right accessories or wood case, the upside is more about owning a desirable, characterful piece than getting a bargain.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Founded in 1979 in the United States by audio innovator Bob Carver, a physicist and engineer from the Pacific Northwest, the Carver brand emerged from his earlier work at Phase Linear, where he designed groundbreaking amplifiers like the 1972 Phase Linear 700—the most powerful consumer amp of its era. Carver Corporation quickly built on this foundation, delivering hand-crafted amplifiers that combined cutting-edge technology with immense power at accessible prices, revolutionizing high-fidelity sound for everyday enthusiasts.
Carver specialized in power amplifiers, preamplifiers, and integrated systems, earning acclaim for magnetic field amplification and other proprietary designs that prioritized performance over luxury pricing. The brand expanded into professional audio with Carver Professional in 1984 and home cinema via Sunfire in 1994, while maintaining a core focus on robust, high-output electronics rather than speakers, turntables, DACs, headphones, or cables.
Positioned as a populist force in the hi-fi market, Carver brought audiophile-grade power to the middle class, rivaling elite brands at a fraction of the cost and fostering a loyal following among vintage collectors today. Though corporate shifts and the 2024 closure of Bob Carver Corp marked challenges, its legacy endures as mid-tier innovation that democratized excellence, now overseen by Carver Holdings Group.
