This is a buyer's market at this price: USD 425 is essentially fair, sitting just above the USD 420 median and comfortably within the recent USD 384–457 range. It is not a bargain, but neither is it overpriced; with unknown condition, a buyer should want a convincing functional description before paying full ask.
The GFP-565 remains a serious, versatile vintage preamp, especially for its quiet, accurate line stage, integrated phono section, extensive switching, and useful bypass outputs that remove the tone circuitry from the signal path. Those bypass outputs can sound notably cleaner and more open than the main outputs, while the phono stage is a genuine strength. Because this is a circa-1990 component, verify both channels, input selection, controls, phono operation, and absence of hum, hiss, or intermittent switches; documented testing would make USD 425 quite reasonable.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
ADCOM emerged in the 1970s as a family-owned American audio venture founded by audiophile Newt Channin, initially focusing on exceptionally musical moving-coil phono cartridges that set it apart from typical entrants. The brand quickly pivoted to electronics with the groundbreaking GFA-1 power amplifier in 1979, delivering 200 watts per channel and robust current for demanding speakers, propelling ADCOM into prominence during the high-fidelity boom of the 1980s and 1990s.
The company built its legacy on high-performance amplifiers, including the Nelson Pass-designed GFA-555 that garnered worldwide acclaim, alongside AV tuners, preamps, and multichannel power amps like the GFA-6000 tailored for home theater. While early roots lay in phono gear, ADCOM specialized in electronics offering superior sound quality without extravagant pricing, eschewing speakers, headphones, or extensive cabling lines.
Positioned firmly in the mid-fi realm, ADCOM defined accessible high-end audio for discerning buyers, blending value and performance that rivaled pricier competitors. After challenges and ownership shifts—including a Thai firm and a faltering 2010 relaunch—the brand staged a robust comeback in 2024 under J&B Distribution, reviving classics like the GFA-555ms alongside modern integrated amps and preamps, reclaiming its spot among savvy audiophiles seeking reliable, soul-stirring sound.
