This US$349 listing for the used Adcom GFP-565 is a strong deal, sitting well below the 25th percentile (US$375) of recent comparable asking prices. With a median market value of US$397 and the 75th percentile at US$421, you are securing this unit for roughly US$48 less than the typical buyer pays, making it an excellent entry point for this sought-after preamp.
The GFP-565 remains a vintage favorite for its clean, transparent sound and robust build quality, offering a versatile full-function design with a high-quality phono section that rivals preamps from twice its original cost. Its reputation for reliability and musicality makes it a cornerstone for mid-80s to 90s systems, and at this price, even minor age-related wear is a minor concern compared to the value grab. If the unit is functional and includes standard accessories, this is a buying opportunity worth acting on quickly.

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.
